4 Inch Lift Kit | 2019-2020 Ford F150 Raptor 4WD | 4 Inch Rear Block Kit | BDS Suspension

Configured with a 4 Inch Rear Block Kit, this option delivers a tail-low to level stance, keeping the rear lift height at or just below the front for a traditional truck profile.

Overview

This 4-inch suspension lift kit from BDS Suspension is engineered specifically for the 2019–2020 Ford F150 Raptor. After extensive development, BDS determined that a 4-inch lift height allows for optimal use of the factory-equipped FOX LiveValve shocks while maintaining the full range of suspension travel provided by the factory suspension components. The kit provides clearance for up to 37-inch tires and takes advantage of BDS's high-clearance design for improved ground clearance, strength, and off-road protection, while correcting suspension and steering geometry for proper on-road handling.

Up front, the kit uses high-arched 1/4-inch thick steel crossmembers, lower strut extensions, multi-piece differential relocation brackets, and a skid plate designed for off-road protection. Steering geometry is corrected at the new ride height with CNC-machined ductile iron steering knuckles, paired with sway bar relocation brackets, brake line brackets, alignment cam bolts, and all necessary 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.
