Rear lift provided by Glide-Ride replacement leaf springs — a multi-leaf progressive design that mounts between the factory axle and leaf springs, corrects pinion angles, eliminates any need for a lift block, reduces axle wrap, and maintains factory payload weight ratings. Note: installation requires removal of the fuel tank. Paired with NX2 Nitro Series rear shocks featuring nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, a 1-3/8-inch high-flow piston, dual-welded ends for increased strength, and self-lubricating seals with a silver powder coat finish.
Overview
This BDS 4.5-inch lift kit is designed for 2007–2013 Chevy Silverado and GMC Sierra 1500 2WD trucks. The kit provides clearance for up to 33-inch tires while correcting suspension and steering geometry for proper on-road handling at the new ride height. Up front, the kit uses full-length replacement strut shocks, high-arched 1/4-inch thick steel crossmembers, heavy duty skid plates, CNC-machined ductile iron steering knuckles, sway bar drops, bump stop extensions, brake line brackets, CV spacers, and all necessary hardware. In the rear, the kit is available with either a replacement lift block or full Glide-Ride leaf springs, along with new u-bolts, brake line brackets, and a choice of NX2 Nitro or FOX 2.0 Performance Series shocks.
Features
- High-clearance crossmember design maximizes ground clearance using 1/4-inch thick laser-cut steel

- CNC-machined ductile cast iron steering knuckles correct steering geometry at the lifted ride height and maintain factory tie rod end compatibility and ESC system compliance
- Rear options include a cast iron lift block (retains ride quality and load capacity) or Glide-Ride multi-leaf progressive replacement leaf springs
- Choice of FOX 2.0 Performance Series IFP monotube or NX2 Nitro Series twin-tube rear shocks
- Factory Protection Plus drivetrain warranty included
- Includes sway bar drops, bump stop extensions, brake line brackets, CV spacers, u-bolts, and all necessary hardware
