Mardarth Engine Motor Mount Kit for GM 3.6L Traverse/Enclave/Acadia 2009-2019 — 4-Piece OE-Style, Vibration-Reducing

Mardarth's 4-piece engine motor mount replacement kit restores stable engine positioning and reduces vibration for 2009–2019 GM 3.6L Traverse, Enclave, Acadia and compatible Saturn models.

If your SUV or crossover with the GM 3.6L V6 has started to exhibit extra vibration, clunks during acceleration or gear changes, or visible engine movement, worn engine and transmission mounts are often the cause. This Mardarth kit supplies a complete set of four mounts — front and rear motor mounts, a rear torque strut, and the transmission mount — engineered to fit the OE mounting points and match common OEM and aftermarket part numbers. It’s a direct bolt-on replacement designed for repair shops and DIYers who want to restore ride comfort and drivetrain stability without modification.

How exactly does this motor mount kit reduce engine vibration?

The kit uses high-grade elastomer bonded to a reinforced internal metal structure to isolate and absorb engine movement. By replacing worn or collapsed mounts, the engine’s motion under load is limited, so fewer shocks and vibrations reach the firewall and cabin.

• Premium rubber compound resists heat, oil and road contaminants
• Reinforced internal plates maintain mount geometry under stress
• Engineered to match OEM compliance for predictable damping

Will these parts fit my 2009–2019 Traverse, Enclave, Acadia or Saturn?

Yes — the kit is designed specifically for GM vehicles equipped with the 3.6L engine and automatic transmission across model years listed. It matches multiple OEM and aftermarket part numbers to ensure compatibility.

• Fits 2009–2019 Traverse, Enclave, Acadia and compatible Saturn models with 3.6L and auto transmission
• Cross-referenced to A5548HY, A5549HY, A5458HY, A5444, 25840450, 25840452
• Direct bolt-on replacements; no modification required

What components are included and what do I need for installation?

The package contains the four mounts needed for a full engine and transmission mount service on the specified vehicles. Basic tools and vehicle support are required; some mounts may require light torque sequencing per factory specs.

• Included: Front Motor Mount (A5549HY), Rear Motor Mount (A5548HY)
• Included: Rear Torque Strut Mount (A5444) and Transmission Mount (A5458HY)
• Installation: standard sockets, torque wrench, jack and stands; alignment check recommended after install

How long can I expect these replacement mounts to last?

Longevity depends on driving conditions and exposure to heat/oil, but the kit is manufactured to meet or exceed OEM durability standards. Proper installation and avoiding fluid leaks will help the mounts achieve their expected service life.

• Constructed with oil- and heat-resistant elastomers to slow degradation
• Reinforced internal structure reduces premature deformation
• Regular inspections after major repairs help detect early wear
