Product Details

Looking to run 35" tires with a great factory like ride? Than look no further! This SuperLift 6" lift kit for the 2001-2008 GM 2500HD4x4 has a host of impressive features. This SuperLift allowes the factory upper control arms to be retained and remain in their original location, while the factory lower control arms and axle housing are lowered, in relation to the frame. New Superlift replacement steering knuckles, made of cast ductile iron and machined in-house, span the increased distance between the control arms. Superlift's geometry, from steering timing and linkage angles, to driveshaft and CV axle operating angles, yields optimal component service life and exceptional drivability.

The lower control arm crossmembers are a one-piece, full-width, high-clearance design made of .25" steel plate. A 1/4" steel skid-plate protects the front differential, plus unlike some other brands, the front differential's structural integrity is not compromised by grinding on the cast reinforcement webbing like cheaper manufactures require. 5" blocks lift the rear. The kit is packaged complete with Superlift' Superide shocks. An optional steering stabilizer kit is available.
