About this product
Improve your 2011-2019 Chevy Silverado and GMC Sierra 2500 HD 4WD with this BDS 4.5" lift kit that 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, CNC-machined ductile iron steering knuckles, sway bar links, bump stop extensions, stainless steel brake lines, and CV spacers. The rear uses replacement lift blocks, a u-bolt flip kit for max clearance, and precision-tuned NX2 Nitro or FOX 2.0 shocks.
