Product Description

The Energy Suspension 4.18107R Hyper-Flex Master Bushing Kit is a comprehensive performance suspension upgrade engineered specifically for 1977-1979 Ford F-150 4WD trucks. This complete set replaces worn and deteriorated factory rubber bushings with high-quality polyurethane components that offer superior durability and resistance to oils, road contaminants, and environmental exposure compared to stock rubber. Designed to improve suspension control and handling precision, the Hyper-Flex™ bushings help maintain proper alignment geometry under load and reduce unwanted suspension movement.

This master kit includes all major suspension and steering bushing components - including 4-degree C-bushings, radius arm, track arm, rear spring/shackle, body mount bushings, and tie rod end protection boots - along with the necessary hardware for installation. Ideal for restorations, off-road builds, or enhanced street performance, the 4.18107R set restores stability, improves handling, and extends the life of the suspension system on classic Ford F-150 4WD applications.
