Eibach 0800.250.0500 ERS Race Main Coilover Spring

The Eibach ERS (Eibach Race Spring) Race Main Spring delivers precision suspension tuning for racing and performance applications. This linear-rate main spring forms the foundation of Eibach's renowned double-spring system, designed to transform engine power into optimal track adhesion through perfectly balanced suspension dynamics.

ERS Double-Spring System Technology:

The ERS system combines main and tender springs to provide a softer initial rate when both springs compress together, then transitions to a firmer ending rate once the tender spring fully closes. This main spring determines the final rate of the complete system, while tender springs control initial compression characteristics. With over 700 different spring components available, the ERS system offers virtually unlimited tuning combinations for suspension engineers and enthusiasts.

Key Features:

• Linear-rate characteristic for predictable, consistent performance
• High spring travel and deflection capacity with short mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Superior dynamic durability for extended component life
• Precision manufacturing with tight tolerances
• Advanced corrosion protection through phosphating and epoxy coating
• Block resistance design prevents coil binding
• Part number imprinted on spring indicating rate and dimensions
• Compatible with Eibach tender, helper springs, and connecting plates

Engineered for racing applications where precise suspension control is critical during cornering, acceleration, and braking. Each spring is individually packaged and clearly marked for easy identification and installation.
