UMI bolt-in rear control arm relocation brackets for 1964–1972 GM A-Body models provide selectable drops of 2", 2-3/4" or 3-1/4" to improve launch traction and correct control arm angle on lowered or factory-height cars. Brackets are CAD-designed to fit factory and popular aftermarket arms and feature reinforced flanges so factory bushings bolt right in. Made from 3/16" mild steel, CNC laser cut, shipped with new Grade 8 hardware and installation instructions. They install in about 1–2 hours without drilling or welding and can improve 60-foot times on track-tested setups.
