UMI’s rear lift bars for 1978–1987 G‑Body replace stock rear control arms to improve traction and reduce wheel hop without changing ride height. Using boxed mild steel tubing, CNC machining and greaseable high‑quality bushings, the bars load the chassis under torque to press tires into the ground for harder launches. Multiple mounting settings allow a 2" or 3" drop in arm position, and hardware with detailed instructions is included for bolt‑in or weld installation.
