Eibach 0600.250.1200 ERS Race Main Coilover Spring 2.5" ID x 12" Length

The Eibach ERS (Eibach Race Spring) Race Main Spring is engineered to deliver precise suspension tuning for racing applications. This high-performance coilover spring provides the critical balance between compliance and control, ensuring optimal tire contact while minimizing body roll, squat, and dive during aggressive driving.

ERS Double Spring System:

Part of Eibach's renowned ERS modular spring system, this Main spring works with Tender springs to create a dual-rate suspension setup. The system provides a softer initial rate when both springs compress together, then transitions to a firmer ending rate once the Tender spring fully compresses. With over 700 individual spring components available, the ERS system offers virtually unlimited tuning combinations for suspension engineers and enthusiasts.

Key Features:

• Linear-rate characteristic determines the final rate of the dual-spring system
• High spring travel and deflection capability at short mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Superior dynamic durability and component longevity
• Manufactured to precise tolerances for consistent performance
• Advanced corrosion protection through phosphating and epoxy coating
• Clearly imprinted with part number, spring rate, and physical dimensions for easy identification
• Compatible with Eibach Tender, Helper springs, and Connecting Plates for complete system customization

This Race Main Spring features block resistance and comes individually packaged for protection. Designed for use with coilover dampers in motorsport and high-performance street applications where precise suspension control is essential.
