Rear lift is achieved with a Block Kit that installs in place of the stock block to retain ride quality and load capacity. Paired with FOX 2.0 Performance Series rear shocks featuring a 2-inch impact-extruded aluminum body, internal floating piston (IFP) monotube design, massive 5/8-inch hard chrome plated heat-treated alloy steel shaft, CNC-machined 6061-T6 aluminum mounting ends, and application-specific valving for maximum performance.
Overview
This BDS 4.5-inch lift kit is engineered for 2007–2013 Chevy Silverado and GMC Sierra 1500 4WD trucks. The kit provides clearance for up to 33-inch tires while improving stance, ground clearance, and off-road capability. It takes advantage of BDS's high-clearance design to correct suspension and steering geometry at the new ride height, preserving on-road handling characteristics.
Up front, the kit uses full-length replacement strut shocks, high-arched 1/4-inch thick steel crossmembers, a multi-piece differential relocation bracket, heavy-duty skid plates, CNC-machined ductile iron steering knuckles, sway bar drops, bump stop extensions, brake line brackets, CV spacers, and all required hardware. In the rear, customers can choose between a lift block option or full Glide-Ride leaf spring replacement, along with new U-bolts, brake line brackets, and a choice of NX2 Nitro or FOX 2.0 Performance Series shocks.
