2020-2022 Powerstroke 4" Radius Arm Lift Kit (BDS1551H)

Built to take full advantage of the factory suspension design, with NX2 or FOX 2.0 Series shocks, these 4" radius arm systems correct suspension, steering and driveline geometry. At the heart of this system is a pair of heavy-duty radius arms built to withstand whatever abuse you can throw at them. They use a high clearance design for extra ground clearance and are formed inward to allow for additional clearance of oversized tires. They incorporate factory-style 3-1/4" rubber bushings to minimize road vibrations and allow for a long, maintenance-free bushing life. The arms bolt into the factory mounting points and reposition the front axle to correct the caster angle. The additional 4" of lift comes from a pair of full-length diesel of gas-specific ProRide coil springs.
