This BDS 6" lift kit fits the 2014-2018 Chevy Silverado and GMC Sierra 1500, with clearance for up to 35" tires. It uses BDS's high-clearance design with full-length replacement strut shocks, high-arched 1/4" steel crossmembers, multi-piece differential relocation brackets and heavy duty skid plates for offroad protection. Steering geometry is corrected at the new ride height with CNC-machined ductile iron knuckles that work with factory tie rod ends for proper ESC function, along with sway bar drops, 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 NX2 Nitro shocks.
