BDS 4" lift for the 2000-2006 Chevy Avalanche, Suburban, and Tahoe and GMC Yukon 1500 4WD with clearance for up to 33" tires. For maximum ground clearance, BDS uses a No Torsion Bar Drop System that mounts the torsion bars directly to the top of the lower a-arm, eliminating the torsion bar cross-member drop. Up front it uses torsion bar relocation brackets, 1/4" thick high-arched steel crossmembers, multipiece differential relocation brackets, heavy duty skid plates, and CNC-machined ductile iron steering knuckles. The rear lift uses new coil springs, track bar relocation, sway bar links, and extended bump stops, with brackets for Auto Ride vehicles or NX2 Nitro / FOX 2.0 Performance shocks.
