We replace the factory upper control arms and small weak ball-joints with a pair of 4130 chromoly custom tubular A-arms using 1.25 uniballs to achieve maximum angles that result in more wheel travel over stock. Our arms are built from thick .188w tubing unlike the competition. This in return will give a much better ride than any other kit on the market. These arms also include urethane bushings and all hardware needed to install them. Also included in this new performance system is a pair of Bilstein 5100 Series shocks for the front and rear of the truck. This is a complete system that will add great off-road performance, added ground clearance, and lift to fit larger off-road tires.
