Eibach 1000.250.0275 ERS Race Main Coilover Spring

The Eibach 1000.250.0275 is a high-performance Race Main Spring designed for precision suspension tuning in motorsports and high-performance applications. This linear-rate coilover spring is part of Eibach's world-renowned ERS (Eibach Race Spring) system, engineered to transform engine power into optimal track adhesion through precise suspension control.

ERS Double Spring System:

This Main spring serves as the foundation of Eibach's innovative 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 a firmer ending rate once the tender spring fully closes. With over 700 different spring components available in the ERS lineup, suspension engineers can create virtually unlimited combinations to dial in the perfect setup for any application.

Key Features:

• Linear-rate characteristic determines the final rate of the suspension system
• Shot-peened surface treatment for enhanced fatigue resistance
• High spring travel and deflection capability at short mounting lengths
• Superior dynamic durability for extended component life
• Precision manufacturing with tight tolerances for consistent performance
• Premium corrosion protection through phosphating and epoxy coating
• Clearly imprinted with part number, spring rate, and physical dimensions for easy identification
• Compatible with Eibach connecting plates for Main/Tender spring combinations
• Individual protective packaging to prevent damage

Engineered to balance the need for compliance over road irregularities while minimizing body roll, squat, and dive during cornering, acceleration, and braking. This Main spring can be used alone or paired with Tender springs and Helper springs to create the ideal suspension characteristics for your specific racing or performance application.
