6" Performance System Lift Kit

The Fabtech 6" Performance System suspension lift kit is engineered for 2001-2010 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD 2WD/4WD trucks, offering enhanced suspension performance for both daily driving and off-road use. This system utilizes robust 1/4″ thick, high arched lower control arm crossmembers that are designed to distribute front suspension impact loads evenly through the frame. These crossmembers feature an integrated front differential skid plate and support tubes for added durability. The kit also includes extended length steering knuckles crafted from ductile iron, new knuckle designs introduced in 2007 to reduce track width and keep tires under the fenders, torsion bar drop brackets, and impact struts. Completing the package are extended length sway bar links with urethane bushings, front and rear bump stop brackets, and rear blocks with U-bolts. This comprehensive kit aims to provide superior suspension performance and a more aggressive stance for your heavy-duty truck. Important fitment notes apply: This system is for non-dually models only. Larger tires cannot be installed on OEM wheels, and users may experience some loss of turning radius. The system does not fit models equipped with Quadrasteer. Additionally, installation requires welding, and OEM wheels and tires cannot be used with this kit.
