1999-2006 GM 1500 6" Lift Kit with NX2 Nitro Shocks (BDS179H)

The BDS 6" lift kit for the 1999-2006 Chevy Silverado and GMC Sierra 1500 4WD clears up to 35" tires and uses a No Torsion Bar Drop System that mounts the torsion bars to the top of the lower a-arm for maximum ground clearance. Up front it runs torsion bar relocation brackets, high-arched 1/4" steel crossmembers, multi-piece differential relocation brackets, heavy-duty skid plates, and CNC-machined ductile iron steering knuckles that work with the factory tie rod ends, plus sway bar drops, bump stop extensions, brake line brackets, and CV spacers. The rear offers a replacement lift block or full Glide-Ride leaf springs (4.5" of lift), new u-bolts, brake line brackets, and precision-tuned NX2 Nitro or FOX 2.0 shocks.
