UMI Performance 68-72 GM A-Body Tubular Non-Adjustable Upper Control Arms

Rear control arms are an essential suspension upgrade for your GM vehicle. Stock control arms are often subpar, leading to traction loss and poor handling. Our tubular control arms offer improved performance for both weekend cruising and track use. The ® polyurethane bushings included provide better durability and enhanced ride quality, reducing traction loss. These control arms are a direct replacement that minimizes wheel hop, enhances cornering, and improves track consistency. Installation is quick and easy, taking only about an hour and requiring no drilling. Simply use the existing OEM hardware for a seamless upgrade. Trust in our durable construction, built with precision CNC machining and TIG/MIG welding, and finished with a long-lasting powder coat.
