Prothane 7-312-BL Rear Trailing Arm Bushing Kit for GM B-Body 1978-1996

Restore proper rear suspension operation with the Prothane 7-312-BL trailing arm bushing kit. Designed for GM B-Body full-size vehicles from 1978 through 1996, this kit replaces worn factory bushings with durable polyurethane components that help maintain suspension alignment and control. The black polyurethane construction is engineered for long-lasting performance in demanding street and performance applications.
Prothane polyurethane bushings provide increased resistance to deflection compared with conventional rubber bushings, helping improve rear suspension response and handling stability. By reducing unwanted movement in the trailing arm, the 7-312-BL kit can support more consistent suspension geometry during acceleration, braking, and cornering while preserving a firm, controlled ride.
This Prothane kit is intended for the rear trailing arm application on compatible GM B-Body vehicles and is supplied as a direct replacement-style solution for worn or deteriorated bushings. Verify vehicle fitment and suspension configuration before ordering to ensure compatibility. The components are finished in black and built for dependable service in restoration, maintenance, and performance upgrades.
