Eibach Performance Coil Spring Isolators

Eibach Spring Isolators are precision-engineered components designed to eliminate noise, vibration, and harshness (NVH) caused by metal-to-metal contact between coil springs and suspension components. Part of Eibach's ERS (Race-Spring-System) hardware lineup, these isolators serve as a critical interface between the spring and its mounting perch — delivering smoother, more consistent spring action throughout the full range of suspension travel.

Constructed from machined Delrin, a high-performance acetal resin renowned for its low-friction characteristics, these isolators effectively reduce torsional binding and spring seat friction that can compromise suspension behavior. The result is more predictable, linear spring action and a noticeable reduction in suspension noise and harshness — whether on the street or the track.

Key Features:

• Torsional Binding Reduction — Removes friction during deflection for freer, more consistent spring movement
• Smoother Spring Action — Delivers more consistent performance through the entire range of deflection
• Machined Delrin Construction — Low-friction, durable material resists wear and compression set for long service life
• NVH Elimination — Effectively reduces squeaks, rattles, and noise caused by spring-to-perch contact
• Lightweight Design — Minimal added mass keeps unsprung weight low for optimal suspension response
• Multiple Configurations Available — Offered in a range of inside diameter options to suit a wide variety of coilover and coil spring setups
• Drop-In Installation — Simple placement between coilover spring and perch requires no modification

Eibach's motorsport credentials span decades and the highest levels of global competition. Eibach partners have included AMG, BMW, Ferrari, Ford, Honda, Porsche, Renault F1, Toyota, and many more — proof that their engineering standards translate directly into real-world performance. These Spring Isolators reflect that same commitment to precision, making them a trusted upgrade for coilover builds, performance street applications, and race setups alike.
