UMI rear lift bar set for 1964–1972 GM A‑body vehicles replaces the factory rear control arms to add traction without changing ride height, using axle torque to load the chassis for harder launches and reduced wheel hop. Built from boxed mild steel tubing with greaseable polyurethane bushings and reinforced sway bar sleeves. This weld‑in P/N 4020 kit ships with bare mounting brackets for welding, grade 8 hardware and instructions; rear brackets offer three drop settings to correct instant center on lowered cars.
