This BDS 4" coil-over lift kit fits the 2014-2018 Chevy Silverado and GMC Sierra 1500, running FOX 2.5 coil-overs for added travel and smooth on-road comfort. It uses BDS's high-clearance design with high-arched 1/4" steel crossmembers, multi-piece differential relocation brackets and heavy duty skid plates. Steering geometry is corrected at the new ride height with CNC-machined ductile iron knuckles and replacement tie rod ends for ESC compatibility, along with sway bar links, bump stop extensions, brake line brackets and CV spacers. In the rear, choose a replacement lift block or full Glide-Ride leaf spring option, plus new u-bolts and FOX 2.0 Performance shocks.

The FOX 2.5 coil-overs include a remote reservoir for extra fluid capacity to keep shocks cool, and offer optional Dual Speed Compression adjustment to tune high-speed and low-speed compression damping.
