65-72 GM C10 Motor And Transmission Mounts

The 65-72 GM C10 motor and transmission mounts are engineered polyurethane and steel components designed to replace worn or soft OEM rubber mounts on classic Chevrolet C10 trucks from 1965 through 1972. As a full-size truck platform that dominated decades of American roads, the C10 demands robust engine bay hardware capable of handling both daily driving and spirited acceleration. These mounts isolate engine vibration while maintaining precise drivetrain geometry—critical for vehicles that still see regular use, whether as weekend cruisers or working trucks.

Built from polyurethane with steel reinforcement and a cadmium-plated finish, the 65-72 GM C10 motor and transmission mounts offer superior durability compared to aged rubber that cracks, compresses, and allows excessive movement. Polyurethane is stiffer than rubber, reducing engine rock during hard acceleration and transmission engagement—particularly noticeable during gear changes when factory mounts have deteriorated. The cadmium plating resists corrosion in the underbody environment, extending service life even in salt-treated regions. This kit includes both motor and transmission mounts as a matched set, ensuring balanced support across the powertrain.

Classic Chevy truck owners restoring or maintaining 1965–1972 C10 models benefit most from this upgrade, particularly those who notice excessive engine sway, clunking sounds under load, or visible mount separation during inspection. Installation requires basic mechanical skills and common shop tools; the mounts bolt directly into factory locations without modification. Prothane's proven track record in polyurethane suspension components makes this a trusted choice for long-term reliability. Whether you're preserving an original truck or building a restomod, these mounts deliver the stiffness and longevity that modern driving demands.
