66-79 Ford F100 Body Mount Kit 2WD

The 66-79 Ford F100 Body Mount Kit 2WD is a polyurethane bushing replacement system engineered to restore structural rigidity and reduce body flex on classic Ford fullsize trucks. Over decades of use, factory rubber body mounts deteriorate and compress, allowing the cab and bed to shift independently during acceleration, braking, and cornering—a condition that compounds noise, vibration, and premature wear throughout the chassis. This kit addresses that foundation issue by replacing all body mount bushings with modern polyurethane compounds that maintain their engineered stiffness across temperature and load cycles.

Prothane's polyurethane formulation is significantly more durable than original rubber, resisting oil, ozone, and UV degradation while delivering consistent performance over the truck's operational life. Unlike OEM rubber that hardens and cracks, polyurethane maintains elasticity and load-carrying capacity, effectively locking the body to the frame and eliminating the vague, loose feel that develops in aging trucks. The black elastomer finish integrates seamlessly beneath the body and requires no special maintenance beyond initial installation. This complete kit for 1966–1979 Ford F100 two-wheel-drive models includes all necessary bushings, eliminating the need to source individual components or settle for partial solutions.

Restoration builders, long-haul enthusiasts, and owners seeking to tighten handling dynamics on vintage Ford fullsize trucks benefit most from this upgrade. Installation requires access to the body mount points beneath the cab and bed—typically a weekend project for mechanics with basic frame tools and lift access. Two-wheel-drive F100 trucks are particularly prone to body separation due to lighter rear suspension geometry, making this kit essential for vehicles seeing regular highway use or load hauling. The compact kit footprint (6 x 4.25 x 6.25 inches, 2.4 lbs) ships complete and ready for installation without additional modification.
