This fully boxed panhard bar really make a difference in handling for any 1982-2002 Camaro or Firebird. Modified by welding a 1/8-inch steel plate to box the arms and reinforce the bar for increased rigidity and then black powder coated for a durable and attractive appearance. SLP also installs new polyurethane bushings to help decrease deflection under load and create more control and stability in your Camaro or Firebird's rear suspension. While perfect for street use, these new parts are designed for all forms of racing, from drag racing to auto crossing. These are an easy bolt-on addition to any third-or-fourth-generation "F"-body.
