Prothane 73-87 GM Rear Spring & Shackle Bushings (w/ 1.75in Bushings) - Black

This kit from Prothane gives you the black polyurethane bushings you need to replace the worn-out rubber ones in the rear springs and shackles of your 1973-1987 GM truck. Over time, the original bushings can crack and degrade, leading to a less controlled ride and potential noise. Replacing them with these well-built polyurethane parts can help restore your truck's handling and stability.

These bushings are made from Prothane's durable polyurethane, which is known for its resistance to wear and tear, as well as its ability to maintain its shape under load. The 1.75-inch diameter is specific for many GM rear suspension setups from the mid-70s through the mid-80s. Installing new bushings is a common step when rebuilding or refreshing a truck's suspension, helping to ensure the rear axle stays properly located and the springs can articulate smoothly.
