UMI Performance 1978-1988 GM G-Body Rear Tubular Upper & Lower Control Arms Kit (301516-B)

Fits select 1978-1988 GM G-Body vehicles including Buick Regal, Chevrolet Malibu, Chevrolet Monte Carlo, Oldsmobile Cutlass, and Pontiac Grand Prix or LeMans. This kit provides a comprehensive rear suspension overhaul, replacing weak factory stamped-steel components with high-strength tubular units.

Stock rear control arms are prone to significant bushing deflection and structural flex, leading to wheel hop, traction loss, and unpredictable handling. UMI Performance engineered these arms from heavy-duty 1.625" OD x 0.120" DOM mild steel tubing to maximize rigidity. The kit includes high-quality polyurethane bushings that are greasable on the car via integrated grease fittings, ensuring smooth operation and a significant reduction in deflection compared to OEM rubber bushings. These arms are a direct bolt-on replacement, featuring lower arms with pre-drilled holes for factory or aftermarket sway bars.
