4" Radius Arm Lift Kit w/ 4" Rear Leaf Springs (502H) FITS 80-96 Ford F100/F150 4WD (Dual Front Shocks)
A complete 4" lift system with a reputation of being nearly indestructible. This legendary lift kit system starts with two front Pro-Ride Coil Springs, then adds a new pitman arm for steering correction, heavy duty radius arms and axle pivot relocation brackets. The extended radius arm system will reduce caster change through wheel travel creating a more capable and controlled feeling in the steering wheel both on and off road.
Rear lift kit comes with new custom valved NX² series shocks and is lifted via 2" block and u-bolt kit for easy installation.
Rear options include a dual add-a-leaf kit (shown) or complete new BDS Glide-Ride Leaf Springs.
