Eibach 0800.250.0175 ERS Race Main Coilover Spring

The Eibach 0800.250.0175 is a precision-engineered race main spring designed for high-performance suspension tuning in motorsports applications. This component is part of Eibach's renowned ERS (Eibach Race Spring) system, which allows racers and enthusiasts to fine-tune suspension characteristics through strategic spring combinations.

ERS Double Spring System Technology:

This main spring works within Eibach's innovative double-spring system, which combines main and tender springs to create sophisticated compression characteristics. The main spring provides a linear-rate characteristic that determines the final rate of the system. When paired with a tender spring, the system delivers a softer initial rate as both springs compress together, then transitions to a firmer ending rate once the tender spring fully closes. This progressive behavior optimizes both compliance over road irregularities and body control during aggressive driving.

Key Features:

• Linear-rate main spring characteristic for predictable suspension behavior
• Compatible with over 700 ERS components for virtually unlimited tuning combinations
• High spring travel and deflection capability at short mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Superior dynamic durability for extended component life in racing conditions
• Precision manufacturing with tight tolerances for consistent performance
• Advanced corrosion protection through phosphating and epoxy coating
• Clearly imprinted with part number, spring rate, and physical dimensions for easy identification
• Block resistance design prevents coil binding

Each spring is individually packaged to prevent damage during shipping and storage. The ERS system is designed to work with connecting plates (sold separately) that join main and tender springs, available in both inside and outside diameter configurations depending on damper specifications.
