Eibach Spring Rubber – 5.0in OD, 80 Durometer (Yellow) – Part #SR.500.0080

Achieve precision suspension tuning with the Eibach 80 Durometer Spring Rubber, engineered for professional-level control and fine rate adjustment. Designed to fit 5.0-inch outside diameter coil springs, this durable polyurethane insert allows drivers to quickly modify spring characteristics without changing the entire coil.

Ideal for circle track, drag racing, off-road, or autocross applications, this yellow 80-durometer spring rubber adds mild progressive resistance for smoother transitions and increased corner stability. By inserting between spring coils, it effectively increases spring rate and adds roughly 1.5 inches of solid height, giving tuners a simple, effective way to balance traction and handling.

Key Features:

• Progressive Spring Rate: Adds progressive stiffness to linear race springs for improved handling and grip.

• Durable Polyurethane Construction: 80-durometer design resists compression set and fatigue.

• Fitment: Works with 5.0" outside diameter coil springs.

• Height Adjustment: Adds approximately 1.5" to spring stack height.

• Quick Setup: Easily installs or removes for trackside tuning.

• Made in the USA: Built to Eibach’s world-class engineering standards.

Application Notes:
Compatible with Eibach ERS and similar 5.0" OD coil springs. Sold individually. Available in multiple durometers (50–90) for precise rate tuning.
