Eibach ERS 5.00-Inch Race Spring, 2.25-Inch ID, 310 lb/in Rate

Eibach's ERS line has evolved over the years to be the world's most prominent, comprehensive and superior Race Spring System. Eibach Race Springs are all manufactured in series production, often repeated, with a strong manufacturing experience. Thus, Eibach constantly achieves the most linear spring characteristic (rate) while maintaining the lowest tolerances and the highest quality in the industry.

Brief Description: The Eibach ERS 0500.225.3100 is a high-performance race spring engineered for coil-over suspension systems that require consistent, predictable spring behavior. Developed through Eibach’s extensive motorsports experience, the ERS line delivers repeatable performance, precise spring rates, and dependable quality for competition and performance applications.

Manufactured in series production, the Eibach ERS spring is designed to maintain a highly linear spring characteristic while minimizing manufacturing tolerances. This consistency helps suspension tuners make accurate setup changes and achieve more predictable handling on the track. The spring’s 2.25-inch inside diameter is commonly used with compatible racing coil-over hardware, while its 310 lb/in spring rate provides a balanced foundation for suspension tuning.
