BDS's new 4" lift systems for the 2015 F150 are based off the tried and true 2009-2014 kits, redesigned to fit on the updated 2015 chassis. 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 Fox factory series 2.5 remote reservoir coilovers come pre-tuned with Eibach coil springs for impressive high speed offroad performance. The coilovers are pre-dialed to provide 4" of lift right out of the box to speed up installation. For those needing additional coil-over compression tunability, Fox's DSC (dual speed compression) adjuster coil-overs are available as an upgrade.

Both coilovers are built to outperform out on the trail while offering fade free performance to push your new F150 to the limits. 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 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 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.
