Eibach ERS 5.00-Inch Coil-Over Race Spring, 2.25-Inch ID, 1550 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 0500.225.1550 is a professional-grade coil-over race spring engineered for demanding motorsports and performance suspension applications. As part of Eibach’s ERS line, this spring benefits from extensive manufacturing experience, repeated series production, and precise quality control. Its high spring rate is suited to competition vehicles and specialized setups requiring firm, predictable suspension control.

Performance Benefits: Eibach ERS race springs are designed to provide a highly linear spring characteristic with exceptionally low tolerances. This consistent behavior helps suspension tuners achieve repeatable handling, predictable load response, and accurate setup changes at the track. The spring is intended for use with compatible 2.25-inch inside-diameter coil-over hardware and should be selected according to the vehicle’s weight distribution, suspension geometry, damper settings, and intended application.
