Product Description

The Energy Suspension 4.18107G Hyper-Flex Master Bushing Kit is a comprehensive suspension bushing set engineered for 1973-1979 Ford F-150 4WD trucks. This master kit replaces a vehicle's worn rubber bushings with performance polyurethane components that resist road grime, oils, coolants, and weathering far better than stock rubber. By upgrading to Hyper-Flex™ bushings throughout the chassis, owners can expect improved suspension control, reduced wheel hop under acceleration, and maintained caster and camber alignment under load.

Designed specifically for classic F-150 4WD applications, this kit includes critical suspension and steering bushings like C-bushings, radius arm bushings, track arm bushings, body mounts, rear spring and shackle bushings, and protective tie rod end boots. Whether you're restoring an older 4x4 or upgrading for enhanced street and off-road performance, the 4.18107G set delivers a noticeable increase in handling precision and chassis stability over worn factory components, while the included hardware simplifies the installation process.
