BMR Rear Suspension Kit On-Car Adjustable Polyurethane Black (1978-1987 G-Body) RSK028H
Launch significantly harder, eliminate violent wheel hop, and build cornering consistency into your classic GM G-body platform with the BMR Suspension Rear Suspension Kit. Factory-issued stamped steel control arms coupled with compliant rubber bushings deflect severely under load, absorbing valuable horsepower instead of driving it directly to the pavement. This performance package features a matched set of non-adjustable lower control arms, on-car adjustable upper control arms, and frame reinforcement braces. By swapping out your weak stock links, you eradicate control arm flex and frame deflection for completely repeatable, predictable performance at the drag strip or on the street.
Built for serious street and track duty, the lower control arms are heavy-duty MIG-welded 1.50-inch diameter, 0.120-inch wall DOM steel tubing, providing massive strength upgrades over stock. The upper arms are constructed from 1.25-inch diameter, 0.120-inch wall DOM steel tubing with TIG-welded chrome-moly tube adapters and a CNC-machined center adjuster with rolled threads for effortless on-car pinion angle tuning. To minimize frame flex under heavy cornering or hard launches, the kit includes 1.0-inch diameter, 0.156-inch wall steel tubing reinforcement braces that structurally tie the upper and lower frame mounts together. The entire RSK028H kit comes loaded with greasable, 95-durometer internally fluted Polyurethane Urethane bushings and zinc-coated inner sleeves. These specialized grease channels evenly distribute lubrication to eliminate noise and friction, providing a rigid, crisp connection that handles hard compression loads while safely managing NVH. Proudly made in the U.S.A., this package features a durable black hammertone powdercoat finish.
