BDS 6 Inch Lift Kit | 1999-2006 Chevy Silverado / GMC Sierra 1500 4WD | Block Kit & Add-A-Leaf | NX2 Nitro Series Shocks

Rear lift achieved with a Block Kit and Add-A-Leaf package. The add-a-leaf helps freshen worn factory leaf springs, includes new center pins, reduces axle wrap, and maintains factory payload weight ratings. Installs in place of the stock block. Paired with NX2 Nitro Series shocks featuring a nitrogen-charged twin-tube design, 10-stage velocity-sensitive valving, dual-welded ends, a 1-3/8-inch high-flow piston, self-lubricating seals, and a silver powder coat finish.

Overview

The BDS 6-inch lift kit is designed for the 1999–2006 Chevy Silverado and GMC Sierra 1500 4WD to improve stance, performance, and off-road capability. BDS engineered a No Torsion Bar Drop System that mounts the torsion bars directly to the top of the lower a-arm, eliminating the need to drop the torsion bar cross-member and maximizing ground clearance. The kit provides clearance for up to 35-inch tires and corrects suspension and steering geometry for proper on-road handling at the new taller ride height.

Up front, the kit includes torsion bar relocation brackets, high-arched 1/4-inch thick steel crossmembers, multipiece differential relocation brackets, 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, buyers may choose between a lift block with add-a-leaf or full replacement Glide-Ride leaf springs, along with new u-bolts, brake line brackets, and a choice of NX2 Nitro Series or FOX 2.0 Performance Series shocks.
