This lift kit is built around heavy-duty replacement upper control arms that dwarf the factory components and provide a significantly improved range of motion. These upgraded UCA's are made from fully welded, 1/8" steel plate and CNC-machined ball joint and bushing mounts. The high-quality MOOG ball joints can handle heavy-duty use, and they work in conjunction with stock-style rubber mount bushings to provide a quiet ride. A fully integrated front differential drop and differential skid plate system relocates the differential for optimal driveline angles. Strut spacers provide a full 3.5" of lift and install easily on the factory struts without the need of a strut compressor. A rear 3" block and U-bolt system nets 2" of rear lift and provides an athletic level vehicle stance.

• Fully welded, heavy duty upper control arms that dwarf the factory arms
• CNC-machined UCA bushing and ball joint cups
• OE rubber bushings and greasable factory style ball joints for quiet, reliable, and low maintenance operation

Certain tire/wheel packages can fit with the addition of the provided weld-on steering stops. These are necessary for deeper backspaced wheels to maintain proper tire clearance to the new upper control arms. Do Not combine with any other suspension lift. Does Not Fit 4WD Models. Minor frame and front differential trimming required - see installation instructions for details. Fitment: Will NOT fit 2007 "Classic" models. If you have a 2007 Classic, see kits for comparable 1999-06 models.
