BMR Suspension Rear Suspension Kit for 1978-1987 GM G-Body with Polyurethane ...

BMR Suspension Rear Suspension Kit for 1978–1987 GM G-Body (Polyurethane) Transform traction, reduce wheel hop, and sharpen cornering with the BMR Rear Suspension Kit designed specifically for 1978–1987 GM G-Body models. This kit replaces soft, deflecting stamped-steel arms and rubber bushings with heavy-duty tubular components and high-durometer polyurethane for consistent, repeatable performance under load. Key Features Heavy-duty construction: Lower arms: 1.50" diameter, 0.120" wall DOM steel tubing. Upper arms: 1.25" diameter, 0.120" wall DOM steel tubing. CNC-machined center adjuster: Chrome-moly with rolled threads for precise, durable on-car adjustability. Reinforcement braces: 1.00" diameter, 0.156" wall steel tubing to reduce frame deflection and improve suspension geometry stability. Greasable polyurethane bushings: 95-durometer, internally fluted design retains grease under heavy load for long-lasting, responsive engagement. Performance gains: Improved launch, reduced wheel hop, better power transfer to the tires, and firmer cornering consistency. Why Choose BMR BMR’s engineering focuses on real-world track and street performance. Upgrading to this non-adjustable lower / on-car adjustable upper control arm kit delivers a more solid feel than stock components while maintaining durability for high-power applications. Fitment: Direct-fit for 1978–1987 GM G-Body vehicles. (Part number RSK028)
