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. 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. Lift is achieved by adjusting the pre-load on the factory torsion bars. Aftermarket torsion keys are not needed and worsen the ride quality by adding too much lift.
