Eibach 0600.225.1200 ERS Race Main Coilover Spring

The Eibach ERS (Eibach Race Spring) Race Main Spring is a precision-engineered coilover spring designed for racing applications and serious suspension tuning. This linear-rate main spring serves as the foundation of Eibach's renowned ERS double-spring system, delivering the firm ending rate needed for optimal handling during cornering, acceleration, and braking.

ERS Double-Spring System:

The ERS system combines a Main spring with a Tender spring to create a dual-rate setup. When both springs compress together, the system provides a softer initial rate for absorbing road irregularities and maintaining tire contact. Once the tender spring fully compresses, the Main spring's linear rate takes over, providing the firmer response needed for performance driving. With over 700 different spring components available, the ERS system offers virtually unlimited tuning combinations.

Key Features:

• Linear-rate construction determines the final spring rate of the complete ERS system
• Shot-peened surface treatment for enhanced fatigue resistance
• High deflection capacity delivers maximum end loads at compact mounting lengths
• Precision manufacturing with tight tolerances for consistent performance
• Phosphate and epoxy coating provides superior corrosion protection
• Part number imprinted directly on spring indicates rate and physical dimensions
• Designed to work with Eibach Tender springs and connecting plates
• Compatible with Helper springs to prevent spring looseness at full droop
• Individually packaged for protection during storage and handling

Engineered for racers and suspension specialists who demand precise control over their vehicle's suspension characteristics, this Race Main Spring delivers the durability and performance required for competitive motorsports applications.
