Driver Side (Left) Engine Mount

Product Description
Engineered for reliability and a precision fit, this genuine aftermarket driver side engine mount is a direct replacement for GM OEM parts that restores factory-correct engine positioning and vibration isolation. The mount's internal elastomeric compound is formulated to absorb torsional forces from engine acceleration and deceleration, preventing those forces from transmitting into the cab as noise or harshness.
Proper engine mount integrity is critical to maintaining correct drivetrain alignment — protecting your transmission, CV axles, exhaust components, and engine accessories from premature wear caused by excessive engine movement. This mount is validated to withstand the thermal cycling, oil exposure, and mechanical stress generated by the 5.3L and 6.2L V8 engines over an extended service life.
