Eibach ERS 4.00-Inch Length x 2.00-Inch ID Coil-Over Race Spring

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 coil-over race spring is engineered for serious motorsport and performance suspension applications. As part of Eibach’s renowned ERS line, this spring delivers consistent, repeatable performance with the precision expected from a professionally developed race spring system. Its 4.00-inch free length and 2.00-inch inside diameter support compatibility with select coil-over suspension assemblies designed for this spring format.

Eibach manufactures ERS Race Springs in series production using tightly controlled processes and extensive spring-making experience. This approach helps provide a highly linear spring rate, low manufacturing tolerances, and dependable performance from spring to spring. The result is more predictable suspension behavior, allowing racers and performance enthusiasts to fine-tune vehicle setup with confidence.

Designed for applications where suspension control and repeatability are essential, the Eibach ERS spring is well suited to competition vehicles, track cars, and custom coil-over systems. Verify the required spring rate, free length, inside diameter, and coil-over hardware specifications before installation. This product is an automotive racing component and may require application-specific setup or professional installation.
