Rear Lift Option: Block Kit and Add-A-Leaf — Cast iron tapered lift block with offset steel pin plus an add-a-leaf to refresh worn factory leaf springs.

This 4-inch suspension lift kit from BDS is designed for 1978–1979 Ford Bronco 4WD trucks. The kit is engineered to improve stance, performance, and off-road capability while providing 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 uses a high-strength cast iron lift block, longer U-bolts, and a matching set of NX2 Nitro shocks. Rear leaf spring and add-a-leaf options are also available depending on the selected variant.
Front end alignment required after installation, which may require axle "C" bushing replacement.
