Eibach ERS 4.00 in. Length x 2.00 in. ID Coil-Over Spring, 300 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 engineered for professional motorsports, track vehicles, and performance suspension applications that require consistent spring behavior and precise tuning. Part number Eibach 0400.200.3000 is manufactured as part of the ERS race spring system, providing a dependable foundation for optimizing vehicle handling, ride balance, and suspension response.

Eibach produces ERS springs in repeated series production using extensive spring manufacturing experience and rigorous quality control. This approach helps deliver a highly linear spring rate with low production tolerances, allowing suspension builders and race teams to make predictable adjustments during setup. The spring is designed for compatible coil-over assemblies using a 4.00-inch spring length and 2.00-inch inside diameter, with a 300 lb/in spring rate.

Built for demanding automotive performance use, the Eibach ERS spring supports accurate suspension calibration across a wide range of racing and high-performance applications. Its consistent characteristics make it suitable for custom coil-over configurations where repeatability, quality, and reliable performance are essential. Verify spring dimensions, rate requirements, and coil-over compatibility before installation.
