Prothane 67-87 GM Rear Spring & Shackle Bushings (w/ 1.5in Bushings) - Red

This kit from Prothane gives you the red polyurethane bushings you need to replace the worn-out rubber ones on the rear springs and shackles for your 1967-1987 GM truck or SUV. These bushings are designed to fit into the spring eyes and the shackle links, which are key pivot points for your rear suspension. Replacing old, cracked, or collapsed bushings is crucial for restoring proper suspension geometry and handling.

Prothane uses a specially formulated polyurethane that's more durable than stock rubber. This material offers a good balance between road comfort and suspension responsiveness. The 1.5-inch diameter bushings in this kit are a common size for many GM rear suspension setups from this era. Installing these will help reduce unwanted flex and movement in the rear suspension, leading to a more solid feel when driving and better control, especially under load or during cornering.
