Energy Suspension 9-9005G Coil Spring Isolator Kit Black Polyurethane

The Energy Suspension 9-9005G coil spring isolator (also known as a spring dampener or spring donut) is a universal polyurethane upgrade designed to replace worn rubber spring isolators on your vehicle's suspension. These isolators fit between the coil spring and the spring seat to eliminate noise, reduce vibration, and prevent metal-to-metal contact that can damage components over time.

Key Features:

• Constructed from Energy Suspension's Hyper-Flex polyurethane for superior durability and performance
• Resists deterioration from oil, road salt, undercar chemicals, smog, and ozone exposure
• Will not rot, crack, or compress permanently like OEM rubber isolators
• Maintains consistent performance under demanding conditions including track, street, and off-road use
• Black finish complements any suspension setup
• Universal design fits most coil spring applications
• Race-proven and street-tested for over two decades

Energy Suspension's Hyper-Flex material is formulated with specific durometer characteristics to provide the ideal balance of cushioning and firmness. This upgrade delivers improved handling response, reduced suspension noise, and significantly longer service life compared to factory rubber components. Ideal for restoration projects, performance builds, or simply replacing worn original equipment.
