Eibach 1400.250.0250 ERS Race Main Coilover Spring 2.5" ID x 10" Length

The Eibach 1400.250.0250 is a high-performance race main spring designed for competitive motorsports applications. This coilover spring is part of Eibach's renowned ERS (Eibach Race Spring) system, engineered to deliver optimal suspension performance through precise tuning and exceptional build quality.

ERS Double Spring System:

This main spring forms the foundation of Eibach's innovative double-spring concept, which combines main and tender springs to achieve optimal suspension balance. The system provides 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 features a linear-rate characteristic that determines the final rate of your suspension system, while tender springs control the initial rate for maximum versatility.

Key Features:

• Linear-rate main spring for predictable, consistent performance
• Shot-peened surface treatment for enhanced fatigue resistance
• High spring travel and deflection capacity at compact mounting lengths
• Superior block resistance for extreme compression scenarios
• Phosphate and epoxy coating for premium corrosion protection
• Laser-etched part number indicating spring rate and physical dimensions
• Manufactured to precise tolerances for consistent performance
• Proven dynamic durability for extended component longevity

Engineering Advantages:

Eibach's ERS system offers over 700 individual spring components that can be combined to create nearly unlimited suspension configurations. This flexibility allows suspension engineers and motorsports enthusiasts to fine-tune their setup for specific track conditions, vehicle weight distribution, and driving characteristics. The spring system balances the need for compliance over road irregularities with the firmness required to control body roll, squat, and dive during aggressive cornering, acceleration, and braking.

Each spring arrives individually packaged with comprehensive protective coating to ensure it reaches you in perfect condition, ready for professional racing applications.
