Lift and level your 2011-2019 Chevy Silverado and GMC Sierra 2500 HD 4WD with this BDS 6.5" lift kit, designed around a No Torsion Bar Drop System that mounts the torsion bars directly to the top of the lower a-arm for maximum ground clearance and room for up to 37" tires. The high-clearance front end uses torsion bar relocation brackets, 1/4" thick high-arched steel crossmembers, multipiece differential relocation brackets, HD skid plates, and CNC-machined ductile iron steering knuckles with sway bar links, bump stop extensions, stainless brake lines, and CV spacers to correct geometry. The rear uses replacement lift blocks, a u-bolt flip kit, and precision-tuned NX2 Nitro or FOX 2.0 Performance Series shocks.

A minimum 1/4 inch wheel spacer may be required due to Tire side wall profile variations. A wider Tire will cause clearance issues with the steering knuckle.
