Product Description

The BMR RSK028R Rear Suspension Kit is specifically engineered for 1978-1987 GM G-Body models--including Buick Regal/Grand National, Chevrolet Monte Carlo/Malibu, Oldsmobile Cutlass, and Pontiac Grand Prix. This bolt-on upgrade replaces the flexible stamped steel arms with rugged DOM steel components to dramatically improve launch consistency, reduce wheel hop, and enhance rear-end stability under load.

Featuring on-car adjustable upper arms with CNC-chromoly adjusters, you gain precise control over pinion angle and rear alignment without removing the arms. The non-adjustable lower arms and reinforcing braces, built from heavy-duty DOM tubing, add significant chassis stiffness. Greasable 95A polyurethane bushings with internal flutes provide solid response with long-lasting service.

Proudly made in the USA and finished in red powder coat, the RSK028R maintains OE ride height and geometry while delivering race-tested handling benefits. Whether you're launching hard or carving turns, this kit offers reliable performance and long-term durability backed by BMR's lifetime structural warranty.
