Lift is accomplished via one piece ductile iron drop down steering knuckles attaching to heavy duty 1/4'' thick, high arched lower control arm crossmembers. Fabtech's combination of steering knuckles and high arched crossmembers provides 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 links with urethane bushings retain the factory front sway bar angle. The stock upper control arms and steering centerlink are retained in the factory position and do not have to be removed for installation. The front suspension is completed with crossmember impact struts and torsion bar drop down brackets. Rear lift is accomplished with a 5'' block kit and Add-A-Leaf.
