Maximum’s design replaces the upper control arms with a torque arm and a Panhard rod, each of which has only one job rather than two. The Panhard rod centers the axle from side to side, and the torque arm controls pinion angle. Assigning each of these duties to separate components allows each piece to be better at its one job than the stock upper control arms are at either job. The torque arm is essentially a three-link design, and Maximum claims that it improves traction so much that after installation you may have to alter your sway bars to prevent understeer.
