UMI Performance 64-67 GM A-Body Tubular Non-Adjustable Upper Control Arms

Rear control arms are essential suspension upgrades for GM vehicles. Stock control arms are often subpar, leading to traction loss and poor handling due to bushing deflection and weak material. Our tubular control arms offer the best of both worlds, whether you're a weekend cruiser or a track enthusiast. The polyurethane bushings included provide better performance than OEM rubber bushings, reducing traction loss and improving ride quality. These control arms are a direct bolt-on replacement that minimizes wheel hop, enhances cornering, and improves track consistency. Installation is simple - a 1-hour bolt-on process that requires no drilling and uses OEM hardware.
