Product Description

The BMR RSK028H Rear Suspension Kit is a direct-replacement upgrade for 1978-1987 GM G-Body vehicles (Chevy Monte Carlo/Malibu, Buick Regal/Grand National, Olds Cutlass, Pontiac Grand Prix). It replaces the factory stamped-steel arms and rubber bushings with robust DOM steel arms and 95-durometer polyurethane bushings to eliminate flex and drivetrain lash. On-car adjustable upper arms allow precise pinion angle tuning.

Reinforcement braces help reduce rear subframe twist, improving launch consistency and reducing wheel hop. MIG- and TIG-welded construction, zinc-coated sleeves, and a durable black hammertone finish ensure longevity. Designed for street, drag, and road race use, installation takes approximately 3-4 hours. Backed by BMR's 2-year limited warranty, this kit delivers stiffened rear suspension, improved traction, and more predictable handling with minimal NVH penalty.
