Eibach 0600.225.0500 ERS Race Main Coilover Spring

The Eibach ERS (Eibach Race Spring) Main Spring is a precision-engineered linear-rate coilover spring designed for racing and high-performance suspension applications. This spring serves as the foundation of Eibach's renowned double-spring system, providing the final spring rate once the tender spring fully compresses.

ERS Double-Spring System:

The ERS system utilizes a Main and Tender spring concept that delivers a softer initial rate when both springs compress together, then transitions to a firmer ending rate once the tender spring closes completely. This Main spring features a linear-rate characteristic and determines the final rate of the suspension system. With over 700 different spring components available, the ERS system allows suspension engineers and enthusiasts to create nearly unlimited custom combinations for precise suspension tuning.

Key Features:

• Linear-rate characteristic for consistent, predictable spring performance
• High spring travel and deflection capability with short mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Superior dynamic durability for extended component longevity
• Manufactured to precise tolerances for consistent performance
• Advanced corrosion protection through phosphating and epoxy coating
• Clearly imprinted with part number indicating spring rate and physical dimensions
• Compatible with Eibach Tender, Helper springs, and Connecting Plates

Engineered in Germany using high-grade spring steel, this ERS Main Spring delivers the muscle needed to transform engine power into optimal track adhesion through a properly balanced suspension system. Each spring is individually packaged for protection during storage and transport.
