Prothane 81-87 GM Rear Spring & Shackle Bushings (w/ 1 3/8in Bushings) - Black

These 1 3/8 inch black polyurethane bushings from Prothane are made to replace the worn-out rubber ones in the rear spring and shackle locations on your 1981-1987 GM truck or SUV. Polyurethane is a well-built material that holds its shape better than rubber, which means your suspension will feel more responsive and less sloppy over time.

When the original rubber bushings in your rear suspension start to break down, you might notice a clunking noise over bumps or a general feeling of looseness in the rear end. Replacing them with these solid polyurethane parts helps restore that tight, connected feel to your truck's ride. They are designed to fit right into the factory mounting points, making the installation straightforward for someone comfortable working on suspension components.
