The BDS 4" lift kit for the 2000-2006 Chevy Avalanche, Suburban, or Tahoe and GMC Yukon 1500 4WD clears up to 33" 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, CNC-machined ductile iron steering knuckles, sway bar drops, bump stop extensions, brake line brackets, and CV spacers. The rear uses new coil springs, track bar relocation, sway bar links, and extended bump stops, with brackets for Auto Ride trucks or precision-tuned NX2 Nitro or FOX 2.0 shocks.
