66-79 Ford F100 Body Mount Kit 4WD

The PROTHANE 66-79 Ford F100 Body Mount Kit for 4WD is a polyurethane bushing replacement system designed to restore chassis compliance and eliminate worn rubber isolators on classic Ford full-size trucks. This complete body mount kit addresses a common failure point on 1966–1979 F-Series trucks, where original rubber bushings deteriorate and allow excessive frame-to-body movement, leading to increased vibration, noise, and unwanted rattling throughout the cabin.

Polyurethane body mounts offer significant advantages over OEM rubber. Unlike rubber, which hardens and cracks under UV exposure, temperature cycling, and flex stress, polyurethane maintains elasticity and load-bearing integrity across decades of service. PROTHANE's black formulation is engineered to resist ozone degradation and provide consistent damping properties whether the truck operates in cold mountain terrain or desert heat. The kit format ensures all mounting points are refreshed simultaneously, preventing partial failure modes where some bushings remain worn while others are new. Installation on 4WD F100 models requires frame and body lift separation, making a complete kit cost-effective compared to sourcing individual bushings from multiple suppliers.

This kit targets owners of classic Ford F100 trucks engaged in restoration, daily driving, or off-road use who prioritize eliminating drivetrain noise and improving structural rigidity. Whether the truck serves as a weekend cruiser or a work vehicle, replacing deteriorated body mounts is essential maintenance that improves occupant comfort and reduces stress on adjacent components. The polyurethane material's superior durability compared to stock rubber means owners can expect extended service intervals—a practical consideration for enthusiasts who maintain their own vehicles or operate trucks in demanding conditions.
