Reproduction heavy-duty LH upper control arm for various 1964-72 GM A-Body models. Manufactured to factory specifications, this complete control arm assembly is designed to replace worn, damaged, or missing original components while restoring proper suspension geometry, steering response, and ride quality. Each assembly includes a pre-installed control arm shaft, bushings, and ball joint for a convenient, ready-to-install replacement. Unlike original bolt-retained designs, this heavy-duty control arm features an externally threaded cross shaft with retaining nuts to securely retain the bushings while providing increased strength, durability, and serviceability. Also features a modern flat-top ball joint with a larger load-bearing surface area for improved durability and extended service life. Ideal for restoration projects, performance applications, and routine suspension repairs. LH designates the driver side of the vehicle.
