Eibach 0700.250.0275 Race Application Main Spring - ERS System

The Eibach 0700.250.0275 is a precision-engineered race main spring designed for high-performance motorsport applications. This spring is part of Eibach's renowned ERS (Eibach Race Spring) double-spring system, which allows suspension engineers and racers to fine-tune their vehicle's handling characteristics through nearly unlimited spring combinations.

ERS Double-Spring System Technology:

The ERS system utilizes a Main and Tender spring concept that delivers a softer initial rate when both springs compress together, then transitions to a firmer ending rate once the tender spring fully closes. This race main spring features a linear-rate characteristic and determines the final rate of the complete system. With over 700 different single spring components available in the ERS lineup, you can create a precisely tuned suspension setup tailored to your specific racing needs.

Key Features:

• Linear-rate main spring for predictable suspension behavior
• High spring travel (deflection) with high end loads at short mounting lengths
• Shot-peened surface treatment for maximum fatigue resistance
• Superior dynamic durability for extended component longevity
• Manufactured to precise tolerances for consistent performance
• Advanced corrosion protection through phosphating and epoxy coating
• Block resistance design prevents coil bind
• Clearly imprinted with part number indicating spring rate and physical dimensions
• Individual protective packaging to prevent damage during shipping and storage

Application Notes:

This main spring works in conjunction with Eibach Tender springs (which determine initial rate) and can be paired with Helper springs to prevent the main spring from becoming loose at full droop. Connecting plates are available separately to join main and tender springs. The ERS system provides the precise spring tuning needed to optimize tire contact, reduce body roll, and control squat and dive during competitive racing conditions.
