BDS Suspension 4" Suspension Lift Kit System for the Ford F150 4WD pickup trucks.

FMVSS No.126 compliant

This new lift kit is engineered to the highest standard, using quality materials built right here in the USA. The kit offers a smooth ride and reliable on-road handling coupled with impressive off-road performance and clearance for up to 35'' tires. The 4'' system utilizes a pair of one-piece laser cut 1/4" steel crossmembers, CNC-machined ductile iron steering knuckles, differential relocation brackets, heavy duty differential skid plate, upper strut mount spacers to retain the OE ride quality, bump stop extensions, sway bar relocation, new cam bolts, and billet aluminum driveshaft spacer. In the rear a 4'' offset pin block kit recenters the rear axle in the wheelwell and replacing the factory block to eliminate stacking blocks and level the stance of the truck. Rear brake line extensions and your choice of rear BDS-NX² series or Fox 2.0 shocks round out the kit.

This new 4'' lift kit is certified compliant with the National Highway Traffic Safety Administration's (NHTSA) FMVSS No.126 standards to not adversely effect the factory installed Electronic Stability Control (ESC) Systems installed on the new 2015-16 Ford F150. Along with FMVSS No.126 compliance, all BDS kits include the Factory Protection Plus Program offering peace of mind on road or on the trail. All kits include BDS's No Fine Print Warranty and a 5 year - 60,000 mile PLUS drivetrain warranty for the best lifted suspension protection coverage on the market.
