Unlock professional-grade suspension tuning with the Eibach 90 Durometer Spring Rubber, precision-engineered to add 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.
