Eibach ERS 5.00-Inch Length x 2.25-Inch ID Coil-Over Race Spring, 2100 lb/in

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.

The Eibach ERS 0500.225.2100 is a professional-grade coil-over race spring engineered for high-performance motorsports and competition applications. As part of Eibach’s renowned ERS Race Spring System, it delivers consistent spring behavior, precise load control, and dependable performance under demanding track conditions. The spring is designed for coil-over suspension systems using a 2.25-inch inside diameter and provides a 2100-pound-per-inch spring rate.

Eibach manufactures ERS springs in repeatable series production using extensive spring-development experience and strict quality controls. This process helps maintain a highly linear spring characteristic, low manufacturing tolerances, and consistent performance from one spring to the next. The result is more predictable suspension response, improved tuning accuracy, and reliable support for race teams and performance enthusiasts who require precise chassis control.

The Eibach ERS 0500.225.2100 is suitable for custom suspension setups where spring rate selection is critical to vehicle balance, ride-height control, and handling performance. Confirm spring-rate requirements, available travel, installed height, and coil-over compatibility before installation. This product is intended for automotive racing and performance suspension use; vehicle-specific fitment may vary based on the coil-over hardware and suspension configuration.
