Prothane 81-87 GM Rear 1 3/8in OD Frame Shackle Bushings - Red

When you're working on the rear suspension of your classic GM truck or SUV, replacing worn frame shackle bushings is a common task. These Prothane bushings are designed to fit a wide range of 1969-1991 GM C/K series trucks, Blazers, and Jimmys, helping to restore proper suspension articulation and ride quality. They are made from a durable red polyurethane material that holds up well to the stresses of daily driving and off-road use.

These bushings have a 1 3/8 inch outer diameter and are intended for the frame-side shackle mounts. Polyurethane is a popular choice for suspension components because it offers a good balance of stiffness for control and flexibility for comfort, without the rapid degradation often seen with rubber bushings. Installing these will help reduce unwanted movement and noise from the rear leaf spring setup.
