Eibach Spring Rubber – 2.5in ID, 80 Durometer (Yellow) – Part #SR.250.0080

Fine-tune your suspension with precision using the Eibach 80 Durometer Spring Rubber, built for serious tuners and racers who demand consistent, repeatable performance. Designed to fit 2.5-inch inside diameter coil springs, this polyurethane insert adds moderate stiffness, helping you sharpen handling, improve cornering stability, and dial in spring rate progression without swapping springs.

Eibach’s yellow 80-durometer compound provides the ideal balance between compliance and control, making it a versatile choice for both performance street builds and full race applications. The spring rubber increases effective rate while adding approximately 0.75 inches of solid height, giving you more tuning flexibility for preload and ride height adjustments.

Key Features:

• Moderate Rate Tuning: Adds mid-range stiffness for sharper handling and improved traction.

• Durable Polyurethane Construction: Resists deformation and heat from repeated compression cycles.

• Perfect Fitment: Designed for 2.5" inner diameter coil springs.

• Ride Height Control: Adds about 0.75" of solid height for fine preload adjustment.

• Quick Installation: Installs easily between coils with no tools required.

• Made in the USA: Built to Eibach’s high-performance standards.

Application Notes:
Ideal for coilover-equipped vehicles in road racing, drag, off-road, and autocross applications. Sold individually. Available in multiple durometers (50–90) to match your exact tuning goals.
