The factory GM upper control arms are replaced with Fabtech’s heavy duty ball joint tubular arms. They are constructed with 1.50? OD DOM steel tubing and feature a high travel ball joint that is sizably larger than stock. This provides for increased strength both on and offroad. Fabtech sets the ball joint angle to allow for full travel without bind throughout the travel range.
