2020-2021 Powerstroke 4-Link 6" Coilover Lift Kit (BDS1571F)
Take your new Super Duty to the next level with the tried and true BDS 4-link conversion system. A big upgrade from the factory stamped steel radius arms, these high-strength 4-link conversions offer improved handling, stability, strength, and caster control during wheel travel. Full-length 6" ProRide diesel coil springs are used for the additional ride height paired with Fox 2.5 series coilovers for a smooth ride on any terrain and all-around impressive performance.
