Product details
Rear control arms are one of the most important suspension modifications that can be done to your GM vehicle. Stock control arms are on the borderline of "junk", with weak materials that can lead to traction loss and poor handling. The included polyurethane bushings are an excellent improvement over the OEM rubber bushings, helping to reduce traction loss and improve ride quality. These control arms are a direct bolt-on replacement designed to minimize wheel hop, improve cornering, and enhance track consistency. Whether your vehicle is a street car, drag racer, or restoration project, these arms are a great choice. Please verify whether your vehicle has (1) or (2) upper control arms. Some vehicles have a 3-link rear suspension while others have a 4-link set-up. Note: Sold individually. Upgrade your GM suspension with these rear control arms. Stronger than stock, they reduce traction loss, improve ride quality, and minimize wheel hop. A direct bolt-on fit, they enhance cornering and track consistency. Upgrade GM rear control arms for better traction and handling.
