2001-2010 GM HD / GM 1500 4.5" Lift Kit with FOX 2.0 Performance Shocks (BDS192FS)

The BDS 4.5" lift kit for the 2001-2010 Chevy Silverado and GMC Sierra 2500 HD 4WD improves stance and clears up to 33" 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 drops, bump stop extensions, brake line brackets, and CV spacers. The rear is available with a replacement lift block or full Glide-Ride leaf springs, new u-bolts, brake line brackets, and precision-tuned NX2 Nitro or FOX 2.0 Performance Series shocks. The system offers two knuckle designs: the standard knuckle widens track width without affecting turning radius, while the narrow track knuckle reduces total track width change by about 1.5" but slightly increases the turning radius.
