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.

These control arms are a direct bolt-on replacement designed to  minimize wheel hop, improve cornering and help track consistency.
