Prothane 73-87 GM Rear Spring & Shackle Bushings (w/ 1.5in Bushings) - Black

If you're working on the rear suspension of your 1973-1987 GM truck, these rear spring and shackle bushings from Prothane are what you need. They replace the old, worn-out rubber bushings that connect your leaf springs to the chassis and the shackle links. When rubber wears out, it can lead to a sloppy ride, poor handling, and even clunking noises over bumps. These polyurethane bushings offer a solid upgrade to bring back some responsiveness to your truck's rear end.

Made from Prothane's durable polyurethane material, these bushings are designed to last longer than stock rubber. The black color gives a clean look under the truck. This kit includes the bushings specifically sized for the 1.5-inch spring eyelet, ensuring a snug fit when installed correctly. Replacing these bushings is a common part of restoring or rebuilding the suspension on these classic GM trucks, helping to firm up the ride and improve how the rear axle tracks.
