REAR SUSPENSION KIT, NON-ADJUSTABLE

The BMR Suspension RSK460H Rear Suspension Kit is engineered for 1978-1987 GM G-body vehicles, delivering significant improvements in performance and handling. This kit includes non-adjustable lower and upper control arms, designed to enhance launch capability, minimize wheel hop, and provide consistent cornering performance. Both control arms feature greasable, 95-durometer polyurethane bushings that replace the stock rubber components. These bushings are internally fluted, which retains grease under heavy loads and directs it to the outer edges, ensuring consistent lubrication and quiet operation throughout their lifespan. This design drastically reduces control arm flex and bushing deflection, resulting in improved handling and acceptable noise, vibration, and harshness (NVH) levels.
