BMR Suspension Adjustable Rear Suspension Kit for 1978-1987 GM G-Body - Black Hammertone (RSK028H)

Fits select 1978-1987 Buick Regal, Chevrolet Malibu, Oldsmobile Cutlass, and Pontiac Grand Prix.

Improve launching capability and eliminate wheel hop in your G-body with the BMR Suspension Rear Suspension Kit. Factory stamped steel control arms rely on soft rubber bushings that deflect under load, absorbing power and compromising geometry. This comprehensive kit (RSK028H) replaces those weak points with heavy-duty DOM steel tubing and high-durometer polyurethane bushings for consistent cornering and better traction.

The kit features on-car adjustable upper control arms, allowing for precise pinion angle tuning to optimize drivetrain geometry. The non-adjustable lower control arms provide a rigid foundation, while the included reinforcement braces reduce frame deflection during hard launches. All components are finished in a durable Black Hammertone powder coat for long-lasting corrosion resistance.
