Designed to improve stance, performance, and capability, the BDS 6-inch lift kit for the 2001-2010 Chevy Silverado and GMC Sierra 2500 HD 4WD is a must have upgrade. For maximum ground clearance, BDS designed a No Torsion Bar Drop System where the torsion bars are mounted directly to the top of the lower a-arm eliminating the need to drop the torsion bar cross-member. This kit includes everything necessary to set your truck up right with clearance for up to 35" tires.
