Eibach ERS 4.00 in. Length x 2.00 in. ID Coil-Over Spring, 900 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.

The Eibach ERS Coil-Over Spring is designed for professional motorsports, competition vehicles, and performance-focused suspension applications that require predictable spring behavior and consistent setup results. Eibach's ERS line has evolved into a comprehensive race spring system, offering carefully engineered springs for a wide range of vehicle configurations and suspension requirements.

Manufactured in repeated series production, the Eibach ERS program benefits from extensive manufacturing experience and rigorous quality control. 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 reliable suspension tuning and repeatable handling characteristics on the track.

This Eibach ERS spring uses a 4.00-inch free length, a 2.00-inch inside diameter, and a 900 lb/in spring rate for applications requiring firm, responsive suspension control. The coil-over design is intended for compatible race spring systems and should be matched to the vehicle, damper, spring perch, and overall suspension configuration before installation. Part number Eibach 0400.200.0900 identifies this specific ERS spring specification.

What's Included: One Eibach ERS coil-over race spring.

Fitment: Universal competition-oriented fitment for compatible 2.00-inch ID coil-over suspension systems. Confirm spring dimensions, rate, perch compatibility, and vehicle requirements before purchase.
