Fabtech's 6" lift kit features one-piece ductile iron steering knuckles and 1/4" thick, high arched crossmembers that combine to provide superior ground clearance for the true offroader. The front differential is relocated with a cradle-style bracket using bushings at just the proper angle to allow the use of the factory front driveshaft, without vibration on Autotrac models. Solid steel billet sway bar end liks with urethane bushings retain the factory front sway bar angle. Crossmember impact struts and torsion bar drop brackets, a 5" rear block kit, rear add-a-leaf and front and rear Performance shocks complete this package.
The steering centerlink and stock upper control arms remain in the factory position and do not have to be removed for installation.
