The Belltech FLIP rear drop kit for 2021+ Ford F-150 repositions the original leaf springs to achieve a lowered stance—about 4.5" on 2WD and 5.5" on 4WD—while retaining OEM spring geometry. The kit is powder-coated to resist corrosion and includes axle saddles, high-grade 9/16" U-bolts, notched plates, spring hangers, pinion shims and new shackles with bushings for quieter operation and a direct-fit installation.
