Eibach 0800.250.0225 ERS Race Main Coilover Spring

The Eibach ERS (Eibach Race Spring) Main Spring is engineered for precision suspension tuning in racing and high-performance applications. This linear-rate coilover spring serves as the primary component in Eibach's renowned double-spring system, providing the muscle needed to transform engine power into optimal track adhesion through a properly balanced suspension setup.

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 the desired firmer ending rate once the tender spring fully closes. The Main spring features linear-rate characteristics and determines the final rate of the complete system. With over 700 different spring components available, this system offers nearly unlimited combination possibilities for precise suspension tuning.

Key Features:

• Linear-rate characteristic determines final system rate
• High spring travel (deflection) with high end loads at short mounting lengths
• Shot-peened surface treatment for enhanced durability
• Superior dynamic durability for extended component longevity
• Manufactured to precise tolerances for consistent performance
• Advanced corrosion protection through phosphating and epoxy coating
• Block resistance for bottoming protection
• Part number imprinted on spring indicating spring rate and physical dimensions
• Individual protective packaging
• Compatible with Eibach Tender springs, Helper springs, and Connecting Plates

Eibach ERS springs are the professional's choice for race cars, track day vehicles, and serious performance builds where precision suspension tuning is critical. Each spring is manufactured to exacting standards and designed to work seamlessly with Eibach's complete line of ERS suspension components.
