Energy Suspension Coil Spring Isolator Set - Hyper-Flex Polyurethane

Energy Suspension Coil Spring Isolator Sets are a proven polyurethane upgrade over worn or deteriorated factory rubber isolators. Built with Energy Suspension's proprietary Hyper-Flex™ polyurethane compound, these isolator sets restore quiet, controlled suspension performance by eliminating the squeaks, rattles, and harshness caused by degraded OEM rubber components.

Factory rubber isolators sit between the coil spring and its seat to cushion contact and reduce noise — but over time, rubber degrades from heat, UV exposure, road chemicals, and repeated compression cycles. Once deteriorated, the spring can wear through the isolator entirely, creating a metal-to-metal connection that accelerates wear on the spring and seat while generating unwanted noise. Energy Suspension's Hyper-Flex™ polyurethane solves this problem with a material engineered specifically to resist everything that destroys rubber.

Key Features:

• Manufactured from Hyper-Flex™ polyurethane — Energy Suspension's proprietary high-performance compound, developed and refined over decades of in-house formulation
• Lasts 3 to 10 times longer than conventional OEM rubber isolators — eliminating repeated replacement cycles
• Direct-replacement design assembles to the chassis the same way as factory isolators — no cutting, trimming, or modification required
• Maintains stock ride characteristics without adversely changing suspension behavior
• Resistant to harsh fluids, road salt, grime, UV exposure, and extreme temperature ranges — materials that degrade rubber have no effect on Hyper-Flex™ polyurethane
• Will not dry out, rot, crack, or permanently compress under load
• Minimizes metal-to-metal contact between coil springs and chassis or suspension components
• Available in multiple styles and sizes to cover a wide range of domestic and import vehicle applications

With over three decades of specialization in performance polyurethane, Energy Suspension has established itself as the most recognized name in the category. Each Coil Spring Isolator Set delivers the precision fitment and long-term resilience that polyurethane is known for — a straightforward, cost-effective upgrade for any suspension refresh or rebuild.
