Eibach ERS 4.00 in. Length x 2.25 in. ID Coil-Over Race Spring, 1350 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 Coil-Over Race Spring is engineered for demanding motorsport and performance suspension applications. Part number EIB0400.225.1350 combines a 4.00-inch spring length, 2.25-inch inside diameter, and a 1,350 lb/in spring rate for precise suspension tuning and consistent vehicle control. As part of Eibach’s ERS line, this spring is designed for use with compatible coil-over systems and adjustable race suspension setups.

Eibach manufactures ERS springs in repeatable series production using extensive spring manufacturing expertise. This process helps deliver a highly linear spring characteristic, tight rate tolerances, and dependable quality from spring to spring. The result is predictable suspension performance for competition vehicles, track cars, and other applications where accurate spring behavior is essential.

The Eibach ERS spring is intended for professional installation and should be selected based on vehicle weight, suspension geometry, desired wheel rates, and coil-over hardware compatibility. Confirm the required spring dimensions and rate before installation. This automotive race spring is not supplied as a complete coil-over assembly and does not include mounting hardware or installation tools.
