Product Details

Superlift's 6" 4-LINK Lift Kit for the 2017 Ford Super Duty features set of precision engineered, tubular 4-LINK arms designed to give your ride a truly custom look and an easy install. These heavy duty arms utilize a press fit REFLEX bushing for superior vibration damping, flexibility, and durability. The 4-LINK design optimizes the F-250 and F-350's suspension control and tire wear by limiting caster change through the cycle of the suspension. The 4" lift also contains new, engine specific rated, coil springs that works in conjunction with our track bar relocation bracket to ensure proper steering geometry and track bar phasing.

Like all Superlift lift kits, the 6" 4 LINK Lift Kit for 2017 Ford F250 and F-350 4WD Super Duty is backed by our Limited Lifetime Warranty and Satisfaction Guarantee.
