Eibach 1000.188.0175 Race Main Spring ID Midget Legend - 1.88

The Eibach 1000.188.0175 is a high-performance race main spring designed for Midget and Legend racing applications. Featuring a 1.88-inch inner diameter, this linear-rate spring serves as the foundation of Eibach's renowned ERS (Eibach Race Spring) double-spring system, delivering the precise suspension tuning required for competitive racing.

ERS Double-Spring System:

This main spring is part of Eibach's innovative dual-spring configuration that combines main and tender springs to optimize suspension performance. 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. This allows racers to fine-tune suspension characteristics for maximum grip and control through corners, under acceleration, and during braking.

Key Features:

• Linear-rate characteristic determines the final rate of the suspension system
• Compatible with over 700 different ERS spring components for unlimited tuning combinations
• High spring travel and deflection capacity at short mounting lengths
• Shot-peened surface treatment for superior fatigue resistance
• Phosphate and epoxy coating provides excellent corrosion protection
• Precision-manufactured to tight tolerances for consistent performance
• Clearly imprinted with part number, spring rate, and physical dimensions
• Designed to work with tender springs, helper springs, and connecting plates

Engineered for serious racers and suspension engineers who demand the flexibility to dial in their setup with precision. The ERS system's modular design allows you to adjust suspension characteristics without replacing entire assemblies, making it ideal for teams that test multiple configurations.
