About this product
Improve the stance, performance, and capability of your 2011-2019 Chevy Silverado and GMC Sierra 2500 HD 4WD with this BDS 4.5" lift kit, with clearance for up to 35" tires. For maximum ground clearance, BDS uses a No Torsion Bar Drop System mounting the torsion bars directly to the top of the lower a-arm. Up front it uses torsion bar relocation brackets, 1/4" thick high-arched steel crossmembers, multipiece differential relocation brackets, and heavy duty skid plates, with CNC-machined ductile iron steering knuckles, sway bar links, bump stop extensions, stainless brake lines, and CV spacers. The rear uses replacement lift blocks that retain ride quality and load capacity, a u-bolt flip kit for max clearance, and NX2 Nitro or FOX 2.0 Performance Series shocks.
