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

These Prothane polyurethane bushings are made with a 1 3/8 inch diameter, which is a specific size for the rear spring and shackle on 1981-1987 GM trucks and SUVs. Over time, the original rubber bushings can crack and wear out, leading to a sloppy feel in the rear suspension and potentially affecting handling. Replacing them with these well-built polyurethane parts can help restore a more solid connection between your rear axle and the frame.

Polyurethane is a popular choice for suspension components because it's more durable and resistant to the elements than rubber. This means they tend to last longer and maintain their shape under load, which can contribute to a more consistent feel from your suspension. They are designed to fit right into the factory locations, making them a straightforward replacement for your worn-out parts.
