Exacting engineered CNC machined ductile iron replacement steering knuckles preserve the OEM track width and maintain proper steering geometry through the travel cycle. Knuckles preserve CV extension and prevent CV axle overextension within the OEM tolerances. Aligns to OEM specifications and works properly with Electric Stability Control (ESC) system. The pair of sturdy front and rear drop crossmembers provides a solid mounting point for the OEM lower control arms. A differential skid plate tie the two crossmembers together to create a rigid sub-frame and added protection for vital steering and driveline components. Two separate differential relocation brackets reposition and correct front CV axles and driveshaft angles. Skyjackers torsion bar drop brackets reposition OEM torsion bar crossmember down to parallel the OEM lower control arm mounts. Torsion bar drop brackets are precision engineered to maintain proper suspension geometry. This system integrates smoothly and functions perfectly with OEM suspension. Includes everything necessary for a complete front and rear lift. This all-inclusive kit also has front bump stop brackets, front and rear brake line relocation brackets, differential vent tube extension, front sway bar links and sway bar lowering brackets, cast ductile iron rear blocks with longer Grade 8 U-bolts and lock nuts.
