2021-2025 F-150 4" Lift Kit with NX2 Nitro Shocks (BDS1902H)

BDS steps up the performance and capability of the 2021-2024 Ford F150 trucks with 4-inch suspension lift kits. Designed to improve stance, performance, and capability, this kit includes everything necessary to set your truck up right with clearance for up to 35 inch Tires. This kit takes advantage of BDS's tried and true high-clearance design for improved ground clearance, strength, and offroad protection while correcting suspension and steering geometry for great on-road handling characteristics. Up front the kit utilizes high-arched 1/4-inch thick steel crossmembers, multipiece differential relocation brackets and skidplate designed for offroad protection. Steering geometry is corrected at the new taller ride height with a pair of massive CNC-machined ductile iron steering knuckles. These combined with the provided sway bar relocation brackets, brake line brackets, alignment cam bolts, supplied hardware and more provide a comprehensive front suspension lift ready for use and abuse.
