BDS 4 Inch Lift Kit | Ford F150 Raptor (2017-2018) 4WD | 4 Inch Rear Block Kit

Configured with a 4 Inch Rear Block Kit for a tail-low to level stance, bringing the rear in line with the lifted front.

Overview

This 4-inch suspension lift kit from BDS Suspension is engineered specifically for the 2017–2018 Ford F150 Raptor 4WD. After extensive engineering, BDS determined that the 4-inch lift height provides the best compatibility with the factory-equipped FOX Shocks while maintaining the full range of suspension travel afforded by the factory suspension components. The kit includes everything necessary to install the lift and provides clearance for tires up to 37 inches.

Up front, the kit uses high-arched 1/4-inch thick steel crossmembers, top-mounted strut spacers, multi-piece differential relocation brackets, and a skid plate designed for off-road protection. Steering geometry is corrected at the new ride height using a pair of CNC-machined ductile iron steering knuckles, along with sway bar relocation brackets, brake line brackets, alignment cam bolts, and all required hardware. In the rear, high-strength lift blocks and longer U-bolts lift and level the stance, while rear shock relocation brackets retain the factory FOX internal bypass rear shocks.
