Eibach 0700.250.0600 ERS Race Main Coilover Spring 2.5" ID 6" Length

The Eibach ERS (Eibach Race Spring) Main Spring is a precision-engineered linear-rate coilover spring designed for racing and high-performance suspension applications. A properly tuned spring system provides the muscle needed to transform engine power to the track through optimum tire adhesion, balancing compliance for road irregularities while controlling body roll, squat, and dive during aggressive driving.

ERS Double-Spring System:

This Main spring is part of Eibach's renowned ERS double-spring system, which combines Main and Tender springs to create a sophisticated two-stage rate characteristic. The system provides a softer initial rate when both springs compress together, then transitions to the firmer Main spring rate once the tender spring fully compresses. With over 700 different spring components available, the ERS system offers nearly unlimited tuning combinations for suspension engineers and enthusiasts alike.

Key Features:

• Linear-rate characteristic determines the final system rate
• High spring travel and deflection capacity at 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
• Clearly marked with part number indicating spring rate and physical dimensions
• Compatible with Eibach Tender springs, Helper springs, and connecting plates

The ERS Main Spring is manufactured to exacting standards with high-quality materials and protective coatings, ensuring consistent performance and longevity in demanding racing environments. Each spring is individually packaged for protection during storage and transport.
