Prothane 73-87 GM Rear 1.5in OD Frame Shackle Bushings - Red

Prothane is known for making durable polyurethane suspension components, and these rear frame shackle bushings are a solid example. If you're working on a classic GM truck or SUV from the mid-70s through the late-80s, chances are you'll need to replace these to get your suspension feeling right again. Worn-out rubber bushings can lead to a sloppy ride and affect how your vehicle handles, especially when carrying loads or going over bumps.

These bushings are made from Prothane's signature red polyurethane, which is designed to hold up well over time and resist the kind of degradation that factory rubber can experience. They're a 1.5-inch outer diameter, specifically made to fit the rear frame shackles on a wide range of GM vehicles from 1973 to 1987, including popular models like the Chevrolet C10 and GMC C1500. Replacing these will help restore a firmer feel to your rear suspension.
