This configuration replaces the factory leaf springs with full replacement rear leaf springs. The multi-leaf progressive design delivers a smooth ride, eliminates the need for a lift block, reduces axle wrap, and maintains factory payload weight ratings.
This 4-inch suspension lift kit from BDS Suspension is designed for 1977–1979 Ford F100 and F150 4WD trucks. The kit is engineered to improve stance, performance, and off-road capability, and provides clearance for up to 33-inch tires. Up front, the kit includes Pro-Ride coil springs, radius arm drop brackets, a track bar relocation bracket for steering correction, bump stop brackets, and precision-tuned NX2 nitrogen charged shocks. The rear lift is available in multiple configurations — choose the option that best suits your truck's existing suspension condition and desired performance characteristics.
Alignment "C" bushings may be required. #003408 (4") Leaf Springs and #003608 (6") Leaf Springs come with OE style bushings installed. Add two front auxiliary shocks if the vehicle is equipped with factory dual mounts.
