Tired of that lateral movement in your suspension from the factory Panhard Bar. Saleen and Parnelli Jones have developed a new Watts Link System to partically eliminate lateral movement in your Mustang's Rear Suspension. The Watts Link control the movement of your suspension in the middle, by replacing your differential plate, and attaching the system directly to your car. Not only does this provide a more centered movement to your suspension, but it practically give you the traction of an independent suspension. The kit includes the Watts Link Assembly and Rear Sway Bar.
