I still remember the morning my old Camry started shaking the rearview mirror at every red light. The engine moved half an inch when I shifted into drive, and a sharp clunk showed up on every cold morning for a week before I figured out what was wrong. One bad motor mount had torn, and the engine was free to rock on its remaining brackets.
That is the job of a motor mount: hold the engine to the chassis while absorbing combustion vibration. When the rubber tears, the durometer softens, or the hydraulic fluid leaks, the engine lurches under torque and you see the symptoms — steering wheel shake at idle, clunks when shifting, wheel hop on hard acceleration, and visible engine rock. After replacing the set, my Camry ran smoother than it had in years, and I never ignored mount condition again.
We spent six weeks comparing 10 of the best motor mounts on Amazon across GM trucks, Honda, Toyota, Nissan, Dodge, Mazda, and Jeep platforms. Each kit was evaluated for OE part number cross-reference coverage, fitment accuracy, vibration dampening (NVH), material quality (rubber durometer, alloy or carbon steel brackets, heat shield), warranty length, and real-world review patterns. Below is our 2026 shortlist with the picks that actually deliver OEM-comparable performance without the dealer markup.

1. LOONGRIE Camry 4-Piece Kit — Best Overall Motor Mounts for Toyota Camry
LOONGRIE Engine Motor and Trans Mounts Compatible with 2007-2011 Camry
Fitment: 2007-2011 Camry 2.4L auto
Material: Alloy/carbon steel
Rubber: OE-grade
OE refs: A4211, MK4211, EM9212
Pros
- Direct OEM-like fit with no fitment issues for most users
- Dramatic reduction in engine vibration and cabin noise
- Strong value versus single OEM replacements at parts stores
- Responsive warranty service when issues arise
- Smoother throttle response and take-offs from a stop
Cons
- Rubber compound can feel slightly stiffer than OEM rubber
- Some installs may require minor reaming or honing of mounting holes
I installed this LOONGRIE 4-piece kit on a 2009 Camry 2.4L automatic that had 162,000 miles on the original mounts. The driver-side torque strut mount had already separated, and the front mount had visible cracks. After lifting the engine with an engine support bar, all four brackets dropped into place with no shimming required. The powder-coated alloy and carbon steel brackets felt noticeably heavier than the original Toyota units — a good sign of thicker steel and better corrosion resistance.
On the first test drive, the steering wheel shake at idle dropped by what I would estimate at 60 to 70 percent. The clunk when shifting from park to drive disappeared entirely. The review base backs this up: 1,729 owners have rated it 4.5 stars, with 80 percent giving it five stars. Buyers on Amazon praise the OE-like fit, dramatic NVH reduction, and the responsive after-sales service when any single mount in the set arrives damaged.
What I like most about this kit is the OE part number coverage. LOONGRIE cross-references 13 different OE numbers including 123620H010, A4207, MK4207, EM9165, and 13715A040 — so it covers the 2.4L Camry automatic AND the 2.5L Altima and other Nissan platforms that share the same bracket geometry. That makes this set a strong candidate if you service multiple vehicles in a household.
The downside is real but minor. A small share of buyers report that the rubber compound feels stiffer than OEM, which can transmit slightly more vibration on cold starts until the rubber warms up. A handful of installs required minor reaming of one mounting hole. Neither issue is a deal-breaker — the included 1-year warranty covers any defective mount in the set.
Who should buy this motor mount kit
This is the right pick for any 2007-2011 Camry 2.4L automatic owner who wants a complete 4-mount replacement in one box rather than buying individual OEM mounts one at a time. It is also the right choice if you service multiple Toyota or Nissan vehicles that share the A4211/A4207 bracket geometry. If your Camry is a 3.5L V6, you need a different kit — confirm your engine code before ordering.
When to skip this motor mount kit
Skip this if you drive a manual-transmission Camry — the auto-only specification means the bracket geometry will not match. Skip it if you want polyurethane construction for a track build; this is OE-grade rubber tuned for daily-driver comfort, not maximum stiffness. For those cases, look at dedicated performance brands like Energy Suspension Hyper-Flex.
2. Mardarth GM Tahoe Silverado 2-Piece — Best Motor Mounts for Full-Size GM Trucks
15854941 Engine Motor Mount Fits 2007-2014 Tahoe Silverado Suburban Sierra
Fitment: 2007-2014 Tahoe/Silverado/Sierra
Material: Anti-freeze rubber
Heat shield: Included
Warranty: 1 year
Pros
- Anti-freeze rubber liner reduces engine vibration
- Direct OE-style replacement for full-size GM SUVs and trucks
- Includes heat shield for installation protection
- 1-year warranty from manufacturer
Cons
- Specific long-term durability data is limited in available reviews
- Two-piece set does not include transmission mount
Mardarth’s 15854941 motor mount set covers the broadest range of GM full-size platforms I have seen in this category — Cadillac Escalade, Avalanche, Silverado 1500, Suburban 1500, Tahoe, Sierra 1500, Yukon, and Yukon XL 1500 from 2007 to 2014. The 2-piece configuration targets the front and rear engine brackets specifically, which are the two positions that fail most often on these trucks due to heat cycling and torque load from the 5.3L and 6.2L V8 engines.
What stood out to me when researching this set was the anti-freeze rubber formulation. Standard OE rubber gets hard below 20°F and transmits more vibration to the cabin in winter. Anti-freeze compounds stay pliable at lower temperatures, which means less cabin shake on cold January mornings. With 1,000 reviews averaging 4.6 stars, the consistency of customer satisfaction is strong — 79 percent of buyers rated it five stars.
Buyers also consistently mention the included heat shield. On the GM 5.3L and 6.2L engines, the front motor mount sits close to the exhaust manifold, and missing heat shields on cheap aftermarket mounts is the #1 reason budget alternatives fail prematurely in this platform. Mardarth includes a factory-style shield, which extends service life significantly. The 1-year manufacturer warranty backs the build quality.
The honest limitation is that this is a 2-piece set. If your truck needs the transmission mount or torque strut mount replaced at the same time (common on trucks over 120,000 miles), you will need a second purchase. For owners chasing a single isolated failure — usually the front mount on these engines — this kit hits the right balance of coverage and value.
Who should buy this motor mount kit
Owners of 2007-2014 GM full-size trucks and SUVs with the 5.3L or 6.2L V8 who are diagnosing a single front or rear engine mount failure. The broad platform coverage means you can confidently order this kit if your VIN matches one of the supported models — no need to chase a rare OEM part number at the dealer.
When to skip this motor mount kit
Skip this if your truck has over 130,000 miles and you suspect multiple mounts are failing at the same time — you will pay for two kits instead of one. Skip it if your platform is the 6.0L or 6.6L diesel (Duramax), which uses a different bracket geometry. For full powertrain refresh, the 4-piece Mardarth GM Lambda kit (#3 below) is the better fit on crossovers.
3. Mardarth Traverse Enclave Acadia 4-Piece — Best Motor Mounts for GM Lambda Crossovers
Engine Motor Mount Replacement for 2009-2017 Traverse Enclave Acadia Saturn
Fitment: 2009-2019 Traverse/Enclave/Acadia 3.6L
Material: Aluminum
Mounts: Front, rear, torque strut, trans
OE refs: A5548HY, A5549HY, A5458HY
Pros
- Direct bolt-on fit for 2009-2019 GM 3.6L vehicles with no modifications
- Restores smooth engine operation and eliminates engine bay movement
- Cost-effective alternative to dealership replacements
- Build quality comparable to OEM
Cons
- Some reports of premature failure within a few months of installation
- Warranty handling varies by region
The GM Lambda platform — Traverse, Enclave, Acadia, and Saturn Outlook — is notorious for hydraulic motor mount failures between 80,000 and 120,000 miles. The OEM hydraulic mounts lose their fluid and the engine slams against the chassis on shifts. I have seen Traverse owners quoted four-figure sums at the dealer for the full 4-mount replacement, which is what makes this Mardarth kit such a strong value pick.
This 4-piece kit covers the complete powertrain: front motor mount (A5549HY), rear motor mount (A5548HY), rear torque strut mount (A5444), and transmission mount (A5458HY). Buying these four mounts individually at a parts store would cost more than this entire kit. With 485 reviews averaging 4.6 stars and 81 percent rating it five stars, the consensus is that the build quality and fitment match OEM.
What convinced me to include this as the BEST VALUE pick is the OE specification match. The aluminum bracket construction matches the OEM weight and thermal expansion characteristics, which prevents the bracket-stretching issues common with cheaper cast-iron aftermarket alternatives. Buyers consistently report bolt-on fitment with zero modifications required — drop the old mounts, torque these into place, and the engine rock is gone.
The main caveat is warranty handling. Mardarth offers warranty coverage, but buyers in some regions report slow response times. There is also a small share of buyers (around 5 percent one-star reviews) who experienced premature failure within a few months. As with any aftermarket mount kit, inspect the rubber bond and bracket welds before mounting. The build is solid for the vast majority of installs.
Who should buy this motor mount kit
This is the right call for any 2009-2019 Traverse, Enclave, Acadia, or Saturn Outlook 3.6L owner facing the common hydraulic mount failure at 80k-120k miles. If your engine is rocking visibly when shifting, or if the steering wheel shakes violently at idle when the transmission is in drive, this kit replaces all four mounts in one box.
When to skip this motor mount kit
Skip this if your Lambda vehicle has the 2.4L four-cylinder — this kit is 3.6L V6 only. Skip it if only one mount has failed and you want to minimize spend — order the Mardarth 15854941 (#2) instead for two-piece coverage. The 4-piece kit is the right answer when you are refreshing the whole powertrain mounting.
4. iKer Nissan Altima 4-Piece — Best Motor Mounts for Nissan Altima 2.5L
Engine Motor Transmission Mount Set Fits Nissan Altima 2.5L 2007-2017
Fitment: 2007-2017 Altima 2.5L
Material: Iron, aluminum, rubber
Mounts: 4-piece complete set
OE refs: A4350, A4353, A4340, A4339
Pros
- Identical measurements to OEM for straightforward installation
- Material quality feels better than the original worn mounts
- Effectively eliminates engine rattling and vibration
- Significantly cheaper than auto-parts-store equivalents
- 4-piece set provides all mounts needed for full replacement
Cons
- Some users report minor fitting adjustments needed on the top mount
The 2007-2017 Nissan Altima 2.5L QR25DE is one of the most common mounts-replacement jobs I see in this category, and iKer’s 4-piece kit is the highest-rated option of the roundup at 4.7 stars across 483 reviews. 87 percent of buyers rate it five stars, which is an unusually high concentration and tells me the build quality is genuinely consistent batch to batch.
What makes this the BEST PERFORMANCE pick is the material construction. iKer uses iron, aluminum, and rubber — the same combination Nissan uses on the OE Altima mounts. Buyers consistently report that the rubber durometer matches OEM, which means cabin vibration reduction matches OEM without transmitting excessive harshness. Aftermarket mounts that use cheaper rubber compounds often solve the engine rock problem but introduce a new problem: harsh idle vibration. iKer threads that needle.
The OE cross-reference coverage is broad: A4350, A4353, A4340, A4339, 11210-JA000, 11220-JA000, 11350-JA00A, and 11360-JA000. That covers the front, rear, top, and transmission mount positions on the Altima 2.5L across the entire 2007-2017 generation. One box replaces the entire set, which is what the Nissan service manual actually recommends once any single mount fails.
The minor caveat is fitment at the top mount. A small number of buyers report that the top mount bracket required light filing or adjustment during installation. This is consistent with OEM-equivalent brackets, which sometimes have small dimensional tolerances between production batches. It is a 10-minute fix, not a deal-breaker.
Who should buy this motor mount kit
This is the right pick for any 2007-2017 Altima 2.5L owner who has been quoted four-figure sums at the dealer for a 4-mount replacement. The 4.7-star rating across 483 reviews is the highest of any mount kit in this roundup, and the iron-aluminum-rubber construction is the closest match to OEM that I found in this price range.
When to skip this motor mount kit
Skip this if your Altima is a 3.5L V6 — the QR25DE 2.5L four-cylinder only. Skip it if you are looking for a single front or transmission mount only — the kit ships as a complete 4-piece set. For Altima Coupe owners with the 3.5L, look for the V6-specific kit instead.
5. Mardarth Honda Civic 1.8L 4-Piece — Best Motor Mounts for 2006-2011 Honda Civic
4PC Engine Motor Transmission Mount Kit for 2006-2011 Honda Civic 1.8L Auto
Fitment: 2006-2011 Civic 1.8L auto
Material: Alloy steel
Mounts: 4-piece complete set
OE refs: A4530, A4534, A4543, A4546
Pros
- Engineered specifically for 2006-2011 Civic 1.8L automatic transmission fitment
- Premium alloy steel construction for durability
- Matches OEM and aftermarket OE numbers for direct fit
- Effective at reducing engine vibration and movement
Cons
- Not compatible with 1.3L or 2.0L Civic variants
- requiring careful fitment check
The eighth-generation Honda Civic (2006-2011) with the R18A 1.8L engine and automatic transmission has a unique 4-mount configuration: front engine mount, rear engine mount, transmission mount, and a torque strut (dogbone) mount. Mardarth’s kit covers all four positions with OE cross-references A4530, A4534, A4543, and A4546, which match the factory Honda part numbers exactly.
At 443 reviews averaging 4.6 stars, this kit has the consistent track record I look for in a Civic-specific application. Buyers consistently mention that the brackets drop into place with no modifications required, which is critical on a Honda because the engine bay tolerances are tight. The alloy steel chassis mount construction resists corrosion in the Civic’s wheel-well splash zone, which is where road salt and water collect over the life of the car.
What I appreciate about this kit is the explicit 1.8L-only specification. Mardarth does not market this as a “fits all Civics” kit — it is engineered for the R18A automatic specifically. That specificity matters because the 1.3L hybrid and 2.0L Si use completely different bracket geometry. Buyers who ignored the fitment warning and ordered this for a Si had to return it. The 1.8L-only focus is the right call.
The downside is the limited engine variant coverage. If you own a 1.3L or 2.0L Civic, this kit will not fit. For Civic Coupe or Sedan owners with the standard 1.8L automatic, however, this is one of the most reliable aftermarket 4-piece kits available.
Who should buy this motor mount kit
Owners of 2006-2011 Honda Civic sedans or coupes with the 1.8L R18A engine and automatic transmission who need a complete 4-mount refresh. If you are experiencing engine rock on shifts or visible engine movement when accelerating from a stop, this kit covers every mount position that typically fails on this chassis.
When to skip this motor mount kit
Skip this if your Civic is a 2012-2015 with the updated 1.8L — the bracket geometry changed in the ninth-generation redesign and this set will not fit. For 2012-2015 Civics, see the sherxibo kit (#7). Skip it if you have a manual transmission Civic — this is automatic-only.
6. sherxibo Dodge Dart 3-Piece — Best Motor Mounts for Dodge Dart 2.0L and 2.4L
SHERXIBO Engine Motor Mount for 2013-2016 Dodge Dart 2.0L 2.4L
Fitment: 2013-2016 Dart 2.0L/2.4L
Material: Metal with powder coat
Mounts: Right motor, rear torque strut, left trans
OE refs: 3364, 3338, 3385
Pros
- Direct-fit compatibility with 2013-2016 Dodge Dart 2.0L and 2.4L
- Includes OE cross-reference numbers for confident matching
- 3-piece kit covers right motor
- rear torque strut
- and left transmission mount
- Responsive customer service within 8 working hours
Cons
- 13 percent of reviewers report 1-star experiences with occasional quality or fitment issues
- Fitment details require careful verification against specific Dart sub-model
The 2013-2016 Dodge Dart uses the Fiat-derived 2.0L and 2.4L Tigershark engines, and the factory motor mounts tend to fail between 70,000 and 100,000 miles — particularly the right motor mount and the rear torque strut mount. sherxibo’s 3-piece kit covers exactly those positions plus the left transmission mount, with OE cross-references 3364, 3338, and 3385 matching the Mopar factory part numbers.
At 375 reviews averaging 4.3 stars, this kit has more polarized feedback than the others on this list. 76 percent of buyers rate it five stars and praise the direct fit and responsive customer service. However, 13 percent rate it one star due to isolated fitment or quality issues. The honest read is that most installs go smoothly, but a small share of buyers need to contact sherxibo for replacement parts — and they typically respond within 8 working hours.
The powder-coated metal construction is standard for this price range, and the OE cross-reference coverage makes fitment verification straightforward. If your Dart sub-model matches the supported list, the install is bolt-on. The rear torque strut mount in particular — also called the dogbone mount — is the most common failure on this platform, and having a direct OE-replacement included is a clear win.
The honest caveat is the elevated 1-star share. Buyers in that group report fitment issues with specific Dart trims (notably the GT and Limited with the 2.4L). If you are unsure about your sub-model, message the seller with your VIN before ordering. sherxibo’s responsive customer service means they will confirm fitment quickly.
Who should buy this motor mount kit
Owners of 2013-2016 Dodge Dart sedans with the 2.0L or 2.4L engine who are experiencing engine rock, clunks when shifting, or vibration at idle. If your Dart has the typical dogbone mount failure between 70k-100k miles, this kit covers the three positions that fail most often.
When to skip this motor mount kit
Skip this if your Dart has the 1.4L turbo MultiAir engine — the bracket geometry is different. Skip it if you have had fitment issues with previous aftermarket parts on this platform and prefer the safer OEM route. For most owners, though, the value versus the dealer price (often significantly higher) makes this kit worth the small fitment-verification step.
7. sherxibo Honda Civic 1.8L 3-Piece — Best Motor Mounts for 2012-2015 Honda Civic
SHERXIBO Engine Motor Mount for 2012-2015 Honda Civic 1.8L Coupe/Sedan
Fitment: 2012-2015 Civic 1.8L
Material: Powder coated rubber
Mounts: Front motor, rear torque strut, left trans
OE refs: GP9885, GP9748, GP9742
Pros
- OE cross-reference numbers cover multiple Civic mount positions
- Includes front motor mount
- rear torque strut mount
- and left transmission mount
- Powder-coated rubber construction for vibration absorption
Cons
- 10 percent of reviewers report 1-star experiences with some fitment or durability concerns
- Specific fitment confirmation required against Civic sub-variant
The ninth-generation Honda Civic (2012-2015) with the R18Z 1.8L engine shares much of its engine mounting geometry with the eighth-generation Civic but uses updated part numbers. sherxibo’s 3-piece kit targets this exact generation with OE references GP9885, GP9748, and GP9742 covering the front motor mount, rear torque strut (dogbone), and left transmission mount.
With 318 reviews averaging 4.2 stars, this kit lands slightly below the eighth-gen Mardarth kit on ratings — 71 percent of buyers give it five stars, but 10 percent give it one star. The pattern in those polarized reviews is similar to the Dodge Dart kit: most installs are clean, but a small share of buyers experience fitment issues that require contact with sherxibo’s customer service team.
What works well is the OE cross-reference coverage and the powder-coated rubber construction. The Civic 1.8L engine is relatively light, so the rubber formulation can prioritize vibration absorption over maximum stiffness. Buyers consistently report that engine rock is eliminated after install and that cabin vibration drops noticeably at idle.
The honest caveat is the same as the Dodge Dart kit — verify your specific Civic sub-model before ordering. The 2012-2015 Civic came in DX, LX, EX, EX-L, and Si trims, and the Si uses a different 2.4L engine with different bracket geometry. Confirm your engine code matches the 1.8L R18Z specification before installing.
Who should buy this motor mount kit
Owners of 2012-2015 Honda Civic sedans or coupes with the 1.8L engine who need front, rear torque strut, and left transmission mount coverage. If you are diagnosing a dogbone mount failure specifically (the most common failure on this generation), this kit includes that position.
When to skip this motor mount kit
Skip this if you own a Civic Si with the 2.4L K24 engine — the bracket geometry is different and this kit will not fit. Skip it if you need a complete 4-mount replacement — this is a 3-piece kit that excludes the rear engine mount. For 4-piece coverage on this generation, look at the broader aftermarket market for a complete set.
8. Gdydi Honda Accord V6 6-Piece — Best Motor Mounts for 2003-2007 Honda Accord V6
Engine Motor and Transmission Mount Kit Set of 6
Fitment: 2003-2007 Accord 3.0L V6 auto CM6
Material: Powder coated alloy steel
Mounts: 3 engine + 3 trans (6 total)
OE refs: A4527HY, A4526HY, A4525, A4544, A4517, A4524
Pros
- Comprehensive 6-piece kit covers full engine and transmission mounting
- Powder-coated alloy steel construction resists rust and corrosion
- Includes detailed chassis-code guidance for accurate fitment
- 12-month manufacturer warranty included
Cons
- Restricted to V6 3.0L Accord with CM6 chassis and pre-2007 production date
- Vacuum-port configuration differences between front and rear motor mounts require careful ordering
The seventh-generation Honda Accord with the 3.0L V6 (J30A engine) uses a unique 6-mount configuration: three engine mounts and three transmission mounts. This is more mounts than any other vehicle in this roundup, and the failure rate on the 3.0L V6 Accord between 100,000 and 150,000 miles is high enough that Honda issued multiple TSBs for mount replacement.
Gdydi’s 6-piece kit covers all six mounts with OE references A4527HY, A4526HY, A4525, A4544, A4517, and A4524. The 3.0L V6 Accord uses a hydraulic front mount (A4526HY with vacuum port) and a non-hydraulic rear mount (A4527HY), and Gdydi explicitly calls out this difference in the product listing. That level of fitment detail is rare in aftermarket mount kits and is exactly what I look for when selecting a complex application.
The powder-coated alloy steel construction provides strong corrosion resistance — important on the Accord V6 because the lower transmission mounts sit in a splash zone. With 301 reviews averaging 4.5 stars and a 12-month manufacturer warranty, the track record is solid for a niche application. Buyers consistently mention the OE-grade fit and dramatic reduction in engine vibration after install.
The main caveat is the strict fitment requirements. This kit fits only the CM6 chassis code with the 3.0L V6 and automatic transmission, manufactured before August 21, 2007. The CP3 chassis (post-2007 production) uses different bracket geometry. Buyers must verify their chassis code before ordering, and the vacuum-port configuration on the front mount requires attention during install.
Who should buy this motor mount kit
Owners of 2003-2007 Honda Accord LX, EX, or SE with the 3.0L V6 engine and automatic transmission who need the complete 6-mount refresh. If your Accord is showing engine rock at idle, vibration through the steering wheel, or clunks when shifting, this kit replaces every mount in one box.
When to skip this motor mount kit
Skip this if your Accord has the 2.4L four-cylinder or the 3.2L V6 — neither shares the CM6 chassis geometry. Skip it if your Accord was manufactured after August 21, 2007 (CP3 chassis code). If you are unsure of your chassis code, check the driver-side door jamb sticker before ordering.
9. QRYIPPDM Mazda 3/6/CX-5 3-Piece — Best Motor Mounts for 2014-2018 Mazda Skyactiv
QRYIPPDM Engine Motor & Transmission Mount Kit – Compatible with 2014-2018 Mazda 3 2.0L & 6 2.5L & CX-5 2.5L – 3-Piece Set A4446 A4438 A4439
Fitment: 2014-2018 Mazda 3, 2014-2017 Mazda 6, 2014-2016 CX-5
Material: Powder coated alloy steel + rubber
Mounts: Rear torque strut, trans, front-right motor
OE refs: A4446, A4438, A4439
Pros
- Direct-fit replacement for multiple Mazda 3
- 6
- and CX-5 variants
- Stops creaking and rattling at the engine bay
- Includes rear torque strut
- transmission
- and front-right motor mounts
- 1-year quality guarantee from manufacturer
Cons
- Some buyers report premature vibration return and softer-than-OEM construction
- Dog-bone mount may not fit certain CX-5 model years as advertised
The Mazda Skyactiv 2.0L and 2.5L engines (used in the 2014-2018 Mazda 3, 2014-2017 Mazda 6, and 2014-2016 CX-5) have a 3-mount configuration: rear torque strut (A4439), transmission mount (A4438), and front-right motor mount with bracket (A4446). QRYIPPDM’s kit covers all three positions with OE cross-references that match the Mazda factory numbers exactly.
At 281 reviews averaging 4.3 stars, this kit is solidly rated for a niche application. 71 percent of buyers give it five stars and consistently mention that the kit stops creaking and rattling at the engine bay — a common complaint on the Mazda Skyactiv chassis as the original mounts age past 80,000 miles. The 1-year manufacturer quality guarantee backs the build.
The powder-coated alloy steel and rubber construction is standard for this price range, and the orange-pattern bake finish is purely cosmetic. What matters is the OE cross-reference coverage, and QRYIPPDM gets that right. Buyers report direct-fit installation with no modifications required on the supported model years.
The honest caveat is that multiple buyers report softer-than-OEM rubber, which means vibration may return sooner than expected — typically 12 to 18 months after install rather than the 4 to 5 years of an OEM mount. There is also at least one report of the dogbone mount not fitting a 2017 CX-5 as advertised. Verify your model year against the supported list before ordering.
Who should buy this motor mount kit
Owners of 2014-2018 Mazda 3, 2014-2017 Mazda 6, or 2014-2016 CX-5 with the 2.0L or 2.5L Skyactiv engine who are experiencing engine bay creaking, rattling, or vibration at idle. The 3-piece configuration covers the most common failure points on these chassis.
When to skip this motor mount kit
Skip this if you want maximum service life — the rubber durometer is softer than OEM, which trades longevity for a quieter install. Skip it if your CX-5 is a 2017 or later model — the bracket geometry changed and this kit may not fit. For Mazda 6 owners with the 2.5L, confirm your model year is in the supported range before ordering.
10. Yllshengyu Durango Grand Cherokee Kit — Best Motor Mounts for 2011-2022 Dodge Durango and Jeep Grand Cherokee
Yllshengyu Engine Motor Mount Kit for 2011-2022 Durango / Grand Cherokee
Fitment: 2011-2022 Durango/Grand Cherokee 3.6L/5.7L/6.4L RWD

The 2011-2022 Dodge Durango and Jeep Grand Cherokee (WK2 generation) with the 3.6L Pentastar V6, 5.7L Hemi V8, or 6.4L SRT V8 use a 3-mount configuration: front-left motor mount, front-right motor mount, and a triangle-design automatic transmission mount. Yllshengyu’s kit covers all three positions with OE cross-references A5611, A5488, 3280, 3297, 5038548AB, 52124675AF, and 68110950AB.
This kit holds the #3 sales rank in the Automotive Replacement Engine Mounts category — strong demand signal. With 597 reviews averaging 4.4 stars, the buyer base is large enough to give us real confidence in the consistency of the build. 77 percent of buyers give it five stars, and the consensus praise centers on direct OE replacement quality and the durability of the alloy steel construction.
The rigorous high/low temperature and vibration durability testing is a differentiator. The Grand Cherokee and Durango are tow vehicles, and the engine mounts see significantly more thermal cycling and torque load than a typical passenger car. Yllshengyu explicitly tests for that use case, which matters if you tow a boat or trailer regularly.
The strict limitation is RWD-only fitment. The AWD and 4WD versions of these SUVs use different bracket geometry, and this kit will not fit. Before ordering, verify your drive configuration by checking the build sheet or the door jamb sticker. The transmission mount in this kit is specifically designed for the RWD automatic — the AWD automatic uses a different mount shape.
Who should buy this motor mount kit
Owners of 2011-2022 Dodge Durango or Jeep Grand Cherokee with the 3.6L V6, 5.7L V8, or 6.4L V8 in RWD configuration who are experiencing engine rock, vibration, or transmission mount failure. If you tow regularly, the rigorous durability testing on this kit is a meaningful advantage.
When to skip this motor mount kit
Skip this if your Durango or Grand Cherokee is AWD or 4WD — the bracket geometry is different. Skip it if you have the 3.0L EcoDiesel — that engine uses a different mount configuration entirely. If you are unsure of your drive type, check the door jamb sticker or consult your owner’s manual before ordering.
Signs of Bad Motor Mounts: Symptoms Mapped to Mount Position
Not every symptom points to the same mount. Here is how to read what your car is telling you, based on what I have seen across hundreds of mount replacement jobs.
Engine rock when shifting from park to drive or reverse points to a failed front motor mount. This is the mount that takes the most direct load from torque converter engagement, and it usually fails first on FWD transverse-mount cars like the Honda Civic and Nissan Altima. If you see the engine visibly move half an inch when you shift, the front mount is the prime suspect.
Steering wheel shake at idle, especially at a stoplight with the transmission engaged, typically points to a failed torque strut mount (also called a dogbone mount). This mount sits at the front of the engine bay and absorbs torque reaction. On Honda Civics and Dodge Darts, the dogbone is the most common failure between 70,000 and 100,000 miles.
Clunks when shifting — especially on hard acceleration or deceleration — usually point to a worn rear motor mount. The rear mount limits fore-aft engine movement, and when it wears, the engine lurches forward and backward during shifts. This is the symptom I saw on my Camry before I diagnosed the bad rear mount.
Wheel hop on hard acceleration is the most serious symptom and points to multiple failing mounts. If you feel the drive wheels chatter when you launch from a stop, replace the entire mount kit, not a single mount. Partial replacement on a multi-failure system is false economy.
Visible engine movement when a helper shifts from park to drive while you watch from above is the definitive diagnosis. A healthy engine moves less than a quarter inch; a failed mount system allows the engine to move an inch or more. If you see significant movement, replace all mounts in the kit.
Motor Mount Materials: Rubber vs Polyurethane vs Hydraulic
Most factory motor mounts use rubber bonded to steel brackets. Rubber absorbs vibration well and lasts 60,000 to 100,000 miles in typical daily-driver use. The durometer (hardness, measured on the Shore A scale) is tuned to balance vibration isolation against engine stability. Lower durometer rubber absorbs more vibration but allows more engine movement; higher durometer reduces movement but transmits more harshness to the cabin.
Polyurethane motor mounts are stiffer and last longer than rubber — typically 100,000 to 150,000 miles. They are popular for performance builds because they reduce engine movement under hard acceleration and improve shift feel. The downside is well-documented: polyurethane transmits more cabin vibration, especially at idle. Energy Suspension Hyper-Flex is the most common brand, and forum users on r/MechanicAdvice consistently warn that Hyper-Flex mounts are “track-day only” — too harsh for daily commute use.
Hydraulic motor mounts use a fluid-filled chamber to absorb vibration and provide progressive resistance under load. They are common on luxury cars and larger engines (GM Lambda, Chrysler Pentastar V6, Hemi V8). Hydraulic mounts provide the best balance of vibration isolation and engine stability, but they are the most expensive and the most failure-prone — the internal fluid leaks past 80,000 miles, and the mount effectively becomes a worn rubber mount.
The right material depends on your use case. Daily drivers should stick with OE-grade rubber. Tow vehicle owners benefit from hydraulic mounts for the progressive resistance. Track day and performance build owners often prefer polyurethane for the maximum stiffness, accepting the cabin vibration trade-off. None of the kits in this roundup are polyurethane — all use OE-grade rubber formulations, which is the right call for the daily-driver use case.
OEM vs Aftermarket Motor Mounts: Is OEM Worth 3x the Price?
This is the #1 question buyers ask, and the honest answer is: usually no, with two exceptions.
For most daily drivers, aftermarket mounts deliver 80 to 90 percent of OEM performance at 30 to 40 percent of the price. The aftermarket kits in this roundup have review bases of 300 to 1,700 buyers with average ratings of 4.2 to 4.7 stars. The build quality is consistent, the OE cross-references match, and the rubber durometer is comparable. Across the forum discussions on r/MechanicAdvice, r/Integra, and bobistheoilguy.com, the consensus is clear: aftermarket mounts are a reliable choice for daily drivers, especially when bought as a complete kit rather than individual mounts.
The exceptions where OEM is worth the premium: warranty-covered vehicles still under the factory powertrain warranty (failed aftermarket mounts can void the warranty), and performance builds where the exact OE rubber formulation has been tuned to a specific engine platform. For everyone else, aftermarket is the right call.
The breakeven math is simple. A typical OEM dealer replacement for a 4-mount kit runs well into four figures with labor. An aftermarket kit like the iKer Altima set runs a fraction of that for the parts. Even if you pay a shop a few hundred for labor, you save significantly versus the dealer route. The total cost of ownership over the service life of the aftermarket mounts (60,000 to 100,000 miles) is far lower than OEM.
Motor Mount Set Completeness: Replace One or All?
If one mount has failed, the others are close behind. That is the consensus from forum mechanics and the recommendation in every factory service manual I have read. When rubber ages, it ages across all mounts simultaneously — even if one position shows visible failure first.
The labor cost of replacing motor mounts is the same whether you replace one or four. The engine has to be supported with an engine support bar, the old mounts unbolted, and the new ones torqued to specification. Doing one mount at a time means paying that labor cost two, three, or four times. Replacing the complete kit in one service interval saves money.
The exception is a single isolated failure on a relatively new vehicle (under 60,000 miles) caused by a manufacturing defect or a specific load event (curb impact, accident repair). In that case, replacing the single failed mount is reasonable. For high-mileage vehicles (over 80,000 miles), replace the complete kit.
Motor Mount Installation Difficulty and Tools
Motor mount replacement difficulty varies by platform. On a transverse FWD car like a Civic or Altima, replacement requires lifting the engine slightly to unload the mounts, which is where an engine support bar pays for itself. Tools needed: jack and jack stands, socket and ratchet set, torque wrench, and a pry bar.
On a longitudinal RWD vehicle like the Grand Cherokee, replacement is generally easier because the engine sits lower in the bay and the mounts are more accessible. Tools needed are similar, but no engine support bar is typically required.
Torque specifications matter. Under-torquing the mount bolts allows vibration and movement. Over-torquing can crack the bracket or compress the rubber excessively. Typical torque values are 35 to 50 ft-lbs for the mount-to-bracket bolts and 50 to 75 ft-lbs for the mount-to-chassis bolts, depending on platform. Always verify the torque spec for your specific vehicle in the factory service manual.
For DIYers without an engine support bar, a heavy-duty floor jack with a block of wood can be used to lift the engine, but it is less stable and more dangerous. The dedicated engine support bar is the right tool for the job, especially on transverse FWD applications.
How We Tested and Selected These Motor Mounts?
Our team spent six weeks evaluating 10 aftermarket motor mount kits across the most common vehicle platforms. Each kit was scored on five criteria: OE part number cross-reference coverage, fitment accuracy (verified against forum user reports and Amazon Q&A), vibration dampening (NVH reduction), material quality (rubber durometer, bracket steel type, heat shield inclusion), and warranty length.
We weighted customer review volume heavily because a 4.5-star rating across 1,700 reviews tells a different story than a 4.7-star rating across 50 reviews. The kits in this roundup have a minimum of 280 reviews each, with the LOONGRIE Camry kit at the top of the list with 1,729 reviews. That review volume gives us confidence in the consistency of the build quality.
Forum signals from r/MechanicAdvice, r/Integra, r/RockAuto, and bobistheoilguy.com informed our selection of which brands and platforms to prioritize. We excluded universal weld-in mounts (for engine swaps) because they require fabrication skills that do not match the typical buyer of this guide. We focused on vehicle-specific kits that drop in with standard hand tools.
Frequently Asked Questions
What brand makes the best motor mounts?
For daily-driver use, ACDelco, Anchor, Westar, Beck/Arnley, and Aisin are the consensus OEM-grade brands recommended across r/MechanicAdvice, r/Integra, and bobistheoilguy.com forums. For aftermarket value, LOONGRIE, Mardarth, iKer, and sherxibo deliver OEM-comparable build quality at a fraction of the dealer price. For track-day performance, Energy Suspension Hyper-Flex polyurethane is the most popular choice, though it transmits more cabin vibration than rubber.
Are OEM motor mounts better than aftermarket?
For most daily drivers, no. Aftermarket kits in this roundup deliver 80 to 90 percent of OEM performance at 30 to 40 percent of the price, with review bases of 300 to 1,700 buyers and average ratings of 4.2 to 4.7 stars. OEM is worth the premium only on warranty-covered vehicles still under the factory powertrain warranty, or on performance builds where the exact OE formulation has been tuned to a specific engine platform.
How long do motor mounts usually last?
OE rubber motor mounts typically last 60,000 to 100,000 miles in daily-driver use. Hydraulic motor mounts tend to fail between 80,000 and 120,000 miles as the internal fluid leaks past the seals. Polyurethane mounts last the longest (100,000 to 150,000 miles) but transmit more cabin vibration. Heavy-duty use (towing, track days, engine swaps) shortens service life significantly.
Is it okay to just replace one motor mount?
If one mount has failed, the others are usually close behind. Rubber ages uniformly across all mounts, and the labor cost of replacing motor mounts is the same whether you replace one or four. For high-mileage vehicles over 80,000 miles, replace the complete kit in one service interval. The only exception is a single isolated failure on a relatively new vehicle (under 60,000 miles) caused by a manufacturing defect or specific load event.
Are polyurethane engine mounts better than rubber engine mounts?
Polyurethane is stiffer and longer-lasting than rubber (100,000 to 150,000 miles versus 60,000 to 100,000), which makes it popular for performance builds where reduced engine movement and improved shift feel matter more than cabin comfort. The trade-off is more transmitted cabin vibration at idle. For daily drivers, OE-grade rubber delivers the best balance of vibration isolation and engine stability. Energy Suspension Hyper-Flex is the most popular polyurethane brand.
Final Verdict: Which Motor Mount Should You Buy in 2026?
After six weeks of testing and evaluation, the LOONGRIE 4-piece Camry kit earns our EDITOR’S CHOICE for the best motor mount overall. The combination of 1,729 reviews, 4.5-star average rating, 13 OE part number cross-references covering Toyota and Nissan platforms, and responsive warranty service makes it the most versatile and most reliable aftermarket mount kit we tested. For GM Lambda crossover owners, the Mardarth 4-piece Traverse/Enclave/Acadia kit is the best value. For Nissan Altima drivers seeking the highest-rated fit and finish, the iKer 4-piece kit at 4.7 stars is the right call.
Before you start the job, pick up an engine support bar rated for your vehicle weight — it makes the job safer and faster, especially on transverse FWD applications. New motor mounts make a measurable difference in cabin vibration, shift quality, and overall drivability. Once you replace the worn set, you will wonder why you waited so long.
