Eibach 1200.250.0165 ERS Race Main Coilover Spring

The Eibach ERS (Eibach Race Spring) main spring is a precision-engineered coilover spring designed for racing and high-performance suspension applications. This linear-rate 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 combines main and tender springs to deliver optimal suspension characteristics. The main spring works with a tender spring to provide a softer initial rate when both compress together, then transitions to the firmer main spring rate once the tender spring closes completely. This configuration allows fine-tuning of suspension response for different track conditions and driving styles.

Key Features:

• Linear-rate characteristic determines final system spring rate
• High spring travel and deflection capacity at short mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Superior corrosion protection through phosphating and epoxy coating
• Precise manufacturing tolerances for consistent performance
• Block resistance design prevents coil binding
• Part number imprinted on spring indicates rate and physical dimensions
• Compatible with over 700 ERS components for custom spring combinations
• High dynamic durability for extended component life
• Individually packaged for protection

Eibach ERS springs are the choice of professional racing teams and serious enthusiasts who demand precision suspension control. The main spring pairs with separately available tender springs, helper springs, and connecting plates to create a fully customizable suspension solution.
