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

Polyurethane isolators, like those made from Energy Suspension's Hyper-Flex material, are significantly more durable than original rubber parts. They resist cracking and degradation, often lasting much longer and saving you from repeat replacements.

Will these isolators change my vehicle's ride quality?

No, these isolators are designed to assemble to the chassis in the same manner as OEM isolators. They are intended to maintain your vehicle's original ride characteristics without adversely affecting comfort or handling.

Are these isolators sold individually or as a set?

The product description indicates this is a coil spring isolator set. Typically, suspension components like these are sold in sets to ensure both sides of the vehicle are addressed for balanced performance.

About this part

Product Details

When you're replacing worn-out suspension components, don't forget the small parts that make a big difference. This front upper coil spring isolator from Energy Suspension is designed to sit between your coil spring and the chassis, preventing metal-on-metal contact and reducing noise. It's a simple yet effective way to maintain your vehicle's original ride characteristics while ensuring a solid connection.

Crafted from Energy Suspension's Hyper-Flex polyurethane material, these isolators are built to last. Unlike rubber isolators that can degrade and crack over time, this material offers significantly improved durability, often lasting three to ten times longer. This means you won't have to worry about replacing them again anytime soon. They assemble to the chassis in the same way as the original equipment isolators, making installation straightforward without altering your vehicle's ride quality.

This isolator fits a wide range of vehicles, including popular models like the 1978-1981 Buick Century, 1976-1990 Buick LeSabre, and 1970-1996 Chevrolet Caprice. It's a solid option for anyone looking to refresh their front suspension with parts that offer improved longevity and maintain factory ride comfort.
