Eibach ERS 4.00-Inch Coil-Over Race Spring, 2.25-Inch Inside Diameter – Part EIB0400.225.0825

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 coil-over race spring is engineered for high-performance suspension applications that demand consistent spring behavior, precise tuning, and dependable quality. Designed for professional and enthusiast racing environments, this spring is manufactured as part of Eibach’s established ERS Race Spring System.

Eibach produces ERS springs in repeatable series production using extensive spring-manufacturing experience. This process helps deliver a highly linear spring rate, tight production tolerances, and consistent performance from one spring to the next. The result is more predictable suspension response and greater control when tuning a race vehicle.

Performance Benefits: The Eibach ERS spring supports accurate suspension setup changes by providing a dependable, repeatable spring rate. Its coil-over design is suitable for compatible racing and performance suspension systems using a 2.25-inch inside diameter spring platform. Verify vehicle, damper, perch, and application requirements before installation.

Fitment: This is an application-specific universal race spring rather than a direct-fit vehicle component. Fitment data was not provided. Confirm the required spring length, inside diameter, rate, installed height, and suspension travel for your setup.
