The UMI 1" tubular rear sway bar for 1978–1988 GM G‑Body cars is a Pro‑Tour style anti‑roll bar that reduces binding and improves stability. It offers three selectable rates (street, auto‑x, road‑race/strip) and CNC‑machined mounts that accommodate common axle tube diameters. The kit includes greaseable polyurethane bushings, zinc‑plated u‑bolts and durable powder coat for long life.
