BDS 4.5 Inch Lift Kit | 2007-2013 Chevy Silverado / GMC Sierra 1500 2WD | Block Kit w/ NX2 Nitro Series Shocks

Rear lift provided by a cast iron lift block that installs in place of the stock block, retaining factory ride quality and load capacity. 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.
