Prothane 81-87 GM K30 Rear Spring & Shackle Bushings (w/ 1.5in OD Frame Shackle Bush) - Red

If you're working on the rear suspension of your 1981-1987 GM K30 truck, these rear spring and shackle bushings from Prothane are a solid option. They are designed to replace the original rubber bushings, which can become worn and cracked over time, leading to a less stable ride and potential handling issues. This kit specifically addresses the spring eye bushings and the frame shackle bushings, ensuring a complete replacement for these critical pivot points.

These bushings are made from Prothane's well-known red polyurethane material. Polyurethane is a popular choice for suspension components because it offers a good balance between durability and performance. It's firmer than stock rubber, which can help reduce body roll and improve steering response, but it's also designed to absorb road vibrations for a comfortable ride. This particular set is for the frame shackle bushings that have a 1.5-inch outer diameter.

Replacing these bushings is a common part of restoring or upgrading the rear suspension on these trucks. It's a job that can make a noticeable difference in how the truck handles, especially when carrying loads or going over uneven surfaces.
