Eibach 0600.250.1000 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 is a core component of Eibach's renowned double-spring system, which allows suspension tuners to create custom spring rate combinations for optimal vehicle dynamics during cornering, acceleration, and braking.

Key Features:

• Linear-rate characteristic that determines the final spring rate of the ERS system
• Compatible with Eibach Tender and Helper springs for infinite tuning possibilities
• Shot-peened surface treatment for enhanced fatigue resistance
• High-quality corrosion protection through phosphating and epoxy coating
• Manufactured to precise tolerances for consistent performance
• High deflection capability and block resistance for maximum spring travel
• Clearly marked with part number indicating spring rate and physical dimensions
• Exceptional dynamic durability for extended component life

The ERS system uses a Main and Tender spring combination to provide a softer initial rate when both springs compress together, then transitions to the firmer Main spring rate once the Tender spring fully compresses. This dual-rate design optimizes tire contact while minimizing body roll, squat, and dive. With over 700 different spring components available, the ERS system offers unmatched flexibility for professional race teams and enthusiasts alike.
