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", bushing deflection and rusting weak  stamped material add for traction loss and poor handling ability. Our  tubular control arms are designed to give you the best of both worlds,  whether your car is a weekend cruiser or a weekend track addict we got  you covered. The included Energy Suspension  polyurethane bushings are an excellent improvement over OEM rubber  bushings, while adding ride improvements they also work excellent to  reduce traction loss. These control arms are a direct bolt-on  replacement designed to minimize wheel hop, improve cornering and help  track consistency. Lower control arms are supplied with sway bar  mounting holes designed for your stock sway bar and most aftermarket  bars.
