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

These are the rear spring and shackle bushings from Prothane, designed for 1973 through 1987 GM trucks and SUVs. If your truck is starting to feel a bit loose in the rear, especially over bumps, worn-out rubber bushings are often the culprit. These polyurethane bushings are a solid option to replace those tired, cracked, or collapsed originals, helping to restore a more controlled and connected feel to your rear suspension.

Prothane uses a durable polyurethane material that holds its shape better than stock rubber, resisting the kind of deformation that leads to sloppy handling. The kit includes bushings with a 1.5-inch outer diameter, which is a common size for this application. Replacing these bushings can make a notable difference in how your truck handles, reducing unwanted movement and noise from the rear leaf spring setup.
