Energy Suspension 16-6104G Coil Spring Isolator Set Black Hyper-Flex Polyurethane

The Energy Suspension 16-6104G Coil Spring Isolator Set is engineered from Energy Suspension's proprietary Hyper-Flex performance polyurethane — a material refined over two decades of suspension engineering. Designed as a direct replacement for deteriorating OEM rubber coil spring isolators, this set delivers improved handling response, reduced noise and vibration, and long-lasting durability that factory rubber simply cannot match. Finished in black, these isolators suit both street-driven builds and show vehicles alike.

Key Features:

• Hyper-Flex polyurethane construction — application-specific durometer (firmness) is carefully selected to match the demands of your suspension system
• Resistant to oils, road salt, ozone, and undercar chemicals — won't rot or deteriorate like OEM rubber components
• Maintains shape under load — engineered to resist permanent compression, preserving suspension geometry and steering response over time
• Race-proven performance — tested on track and street, on-road and off-road, under demanding real-world conditions
• Available in black — clean, finished appearance for show builds or everyday drivers
• Sold as a set — includes all isolators needed for a complete installation

Whether you're restoring a classic, building a performance vehicle, or simply replacing worn-out suspension components, the Energy Suspension 16-6104G Coil Spring Isolators are a proven upgrade over rubber OEM parts. Hyper-Flex polyurethane components are compatible with domestic and import vehicles, front and rear applications, and 2WD or 4WD drivetrains.
