About this product
BDS 6.5" lift for the 2011-2019 Chevy Silverado and GMC Sierra 2500 HD 4WD with clearance for up to 37" 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 with sway bar links, bump stop extensions, stainless steel brake lines, and CV spacers. In the rear it uses replacement lift blocks, a u-bolt flip kit for max clearance, and NX2 Nitro or FOX 2.0 Performance shocks.
