What is the main benefit of using polyurethane coil spring isolators?

Polyurethane isolators are more resistant to wear and tear than original rubber components. They offer better durability and can help maintain their cushioning properties over a longer period, contributing to a quieter ride.

Do these isolators come as a set?

This product is sold as a set, typically enough to replace the isolators on both rear springs for your vehicle. Please check the product details to confirm the exact quantity included.

What other rear suspension components should I consider replacing at the same time?

When working on the rear suspension, it's often a good time to inspect your shocks or struts, sway bar links, and bushings. Replacing worn components together can ensure optimal performance and a more consistent ride.

Product Details

If you're working on the rear suspension of your 1979-1999 Ford Mustang, replacing the coil spring isolators is a smart move. These isolators sit between the coil spring and the chassis, acting as a buffer to soak up road noise and vibrations. Over time, the original rubber or plastic isolators can crack, compress, or wear out, leading to squeaks, rattles, or a harsher ride.

This set from Prothane is made from a durable polyurethane material. Polyurethane is known for its resilience and ability to withstand the stresses of suspension movement and environmental exposure better than stock rubber. Installing new isolators can make a noticeable difference in the comfort of your ride, quieting down the rear end and ensuring the coil spring sits properly against the mounting points.

When you're reinstalling your rear springs, it's a good time to swap out these isolators. They're a relatively inexpensive part that can contribute significantly to a quieter and more comfortable driving experience for your Mustang.
