Spring Rubber Coilover 90 Durometer Blue

Eibach Spring Rubber – 2.5in ID, 90 Durometer (Blue) – Part #SR.2530.0090

The Eibach 90 Durometer Spring Rubber adds progressive rate control to your linear coilover springs. Designed for 2.5-inch inside diameter coilovers, this blue polyurethane insert offers a firm spring rate increase—ideal for high-load applications where maximum handling response and body control are critical.

Eibach’s spring rubbers allow quick and repeatable setup changes without swapping springs. The high-durometer compound provides exceptional durability under repeated compression, maintaining consistent rate tuning on the road course, drag strip, or trail.
