Mardarth Engine Motor Mount Kit for GM 3.6L Traverse/Enclave/Acadia (2009–2019) — 4-Piece Direct Bolt-On, Vibration Dampening

Complete 4-piece motor mount kit designed to directly replace worn mounts on 2009–2019 GM 3.6L Traverse, Enclave, Acadia and Saturn models for smoother, quieter operation.

If your GM crossover or SUV shows signs of excessive engine movement, vibration or transmission shudder, a worn motor mount assembly is often the cause. The Mardarth Engine Motor Mount Replacement kit provides a direct bolt-on swap for the front and rear engine mounts, torque strut, and transmission mount without modifications. It matches multiple OEM and aftermarket part numbers to ensure fitment across many 3.6L automatic-transmission models from 2009 through 2019.

How does this kit improve driving feel and noise?

Replacing deteriorated mounts removes excess engine motion and dampens vibration transferred to the chassis. That results in reduced cabin noise, cleaner gear shifts and a steadier throttle response during acceleration and deceleration.

• Stabilizes engine position under load to prevent clunking and rocking.
• Dampens NVH (noise, vibration, harshness) for a quieter cabin.
• Helps transmission shift more smoothly by keeping alignment consistent.

Will these mounts fit my specific GM vehicle and parts list?

Yes — the kit is engineered for GM vehicles equipped with the 3.6L engine and automatic transmission produced between 2009 and 2019. It’s manufactured to align with several OEM and aftermarket part numbers, so it suits common original and replacement configurations.

• Engineered for 2009–2019 Traverse, Enclave, Acadia, and Saturn 3.6L models.
• Cross-references A5548HY, A5549HY, A5458HY, A5444, 25840450, 25840452.
• Designed as a direct bolt-on replacement — no cutting or custom fabrication needed.

What components are included and how do I plan the replacement?

This Mardarth kit ships as a complete four-piece assembly covering the front and rear motor mounts, the rear torque strut, and the transmission mount. Replacing all mounts together ensures balanced support and prevents premature wear on any single mount.

• 1x Front Motor Mount (A5549HY) and 1x Rear Motor Mount (A5548HY).
• 1x Rear Torque Strut Mount (A5444) for lateral stability.
• 1x Transmission Mount (A5458HY) to maintain driveline alignment.

How durable is the kit and can I install it myself?

Mardarth builds these mounts from quality materials to meet or exceed OEM standards; they’re tested for durability and vibration control. Many experienced DIYers with basic mechanical tools can perform the swap, but professional installation is recommended if you lack lift access or transmission support tools.

• Constructed to withstand engine torque and road stresses for long service life.
• Offered as a cost-effective alternative to dealer-priced replacements.
• Installation typically requires standard hand tools, torque wrench and vehicle support.

Who is this for: This motor mount replacement kit is ideal for owners of 2009–2019 GM crossovers (Traverse, Enclave, Acadia) and compatible Saturn models who are experiencing engine vibration, harsh shifts, or excessive motor movement. It suits DIY mechanics seeking a direct-fit, affordable solution as well as independent shops that need reliable, cross-referenced parts to restore drivability without dealer costs.
