Eibach ERS 3.50 in. Length x 1.63 in. ID Coil-Over 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 spring is engineered for professional motorsports, performance driving, and custom suspension applications that demand consistent spring behavior. As part of Eibach’s renowned ERS Race Spring System, this spring is produced in repeatable series manufacturing with carefully controlled tolerances for dependable performance across demanding track conditions.

Eibach ERS springs are designed to deliver a highly linear spring rate, providing predictable suspension response and consistent vehicle balance. This helps drivers and suspension tuners make precise setup changes while maintaining stable handling characteristics throughout a session. The coil-over configuration is suitable for compatible racing and high-performance suspension systems that use a 3.50-inch spring length and 1.63-inch inside diameter.

Built with Eibach’s extensive spring manufacturing experience, the ERS line emphasizes quality, repeatability, and performance consistency. The compact racing format makes this spring a practical choice for replacement, tuning, or building a custom coil-over suspension setup. Confirm spring rate, installed height, travel requirements, and vehicle-specific fitment before installation. Professional installation and suspension setup are recommended for competition applications.
