Prothane 65-95 GM Rear Upper Coil Spring Isolator - Red

What you get here is a single red polyurethane coil spring isolator from Prothane. This part is designed to sit between the top of your rear coil spring and the vehicle's chassis, acting as a buffer to absorb road noise and vibrations. It's a simple but effective way to quiet down your suspension and improve the ride quality.

This isolator is made from durable polyurethane, which is known for its resilience and ability to withstand the stresses of suspension movement. Unlike softer rubber, polyurethane offers a good balance of flexibility and firmness, helping to maintain spring alignment while still dampening unwanted noise. It's a well-built piece that's made to last in the demanding environment of a vehicle's suspension system.

This particular isolator fits a wide range of GM rear-wheel-drive vehicles from the mid-60s through the early 90s, including models like the Chevrolet Caprice, Buick LeSabre, and Oldsmobile 442. If you're hearing clunks or rattles coming from your rear suspension, or if your old isolators are cracked and worn, this is a straightforward replacement that can make a noticeable difference in ride comfort.
