Configured with a 4 Inch Rear Block Kit for a level to tail-high appearance, paired with NX2 Nitro Series rear shocks featuring a nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, dual-welded ends, a 1-3/8-inch high-flow piston, self-lubricating seals, and a silver powder coat finish.
Overview
This 4-inch suspension lift kit from BDS Suspension is designed for 2015–2020 Ford F150 2WD trucks, improving stance, performance, and off-road capability while providing clearance for up to 35-inch tires. The kit takes advantage of BDS's high-clearance design for improved ground clearance, strength, and off-road protection, while correcting suspension and steering geometry to maintain proper on-road handling characteristics.
Up front, the kit utilizes high-arched 1/4-inch thick steel crossmembers and a skid plate designed for off-road protection. Steering geometry is corrected at the new ride height with a pair of CNC-machined ductile iron steering knuckles. Sway bar relocation brackets, brake line brackets, alignment cam bolts, and all necessary hardware are included for a comprehensive front suspension lift. In the rear, high-strength fabricated lift blocks and longer u-bolts lift and level the stance, complemented by your choice of rear shock absorber.
