Eibach 0600.225.0700 ERS Race Main Coilover Spring

The Eibach ERS (Eibach Race Spring) Main Spring is a precision-engineered linear-rate coilover spring designed for racing and high-performance suspension applications. As part of Eibach's renowned ERS double-spring system, this main spring provides the foundation for creating highly customizable suspension setups that deliver optimal track performance through superior adhesion and control.

ERS Double-Spring System:

The ERS system utilizes a Main and Tender spring concept that offers exceptional tuning flexibility. When combined with a tender spring, the system provides a softer initial rate as both springs compress together, then transitions to the firmer main spring rate once the tender spring fully compresses. This allows suspension engineers to fine-tune initial compliance for road irregularities while maintaining firm control during cornering, acceleration, and braking. With over 700 different spring components available in the ERS lineup, nearly unlimited suspension combinations can be created to match specific vehicle and track requirements.

Key Features:

• Linear-rate characteristic determines the final rate of the suspension system
• High spring travel and deflection capability with short mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Superior dynamic durability for extended component longevity
• Manufactured to precise tolerances for consistent performance
• Advanced corrosion protection through phosphating and epoxy coating
• Clearly imprinted with part number indicating spring rate and physical dimensions
• Compatible with Eibach connecting plates for main/tender spring combinations
• Individual protective packaging to prevent damage during storage and shipping

This main spring is engineered for use with coilover shock absorbers in racing and track applications where precise suspension tuning is critical for optimal performance.
