BDS 6 Inch Lift Kit | 1999-2006 Chevy Silverado / GMC Sierra 1500 4WD | Rear Leaf Springs | NX2 Nitro Series Shocks

Rear lift achieved with full Glide-Ride Replacement Leaf Springs. The multi-leaf progressive design delivers a smooth ride, eliminates any need for a lift block, reduces axle wrap for a more controlled and stable feel, and maintains factory payload weight ratings. 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.
