Eibach 0500.200.1400 ERS Race Main Coilover Spring

The Eibach 0500.200.1400 is a high-performance race main spring designed for the renowned ERS (Eibach Race Spring) double-spring system. This precision-engineered coilover spring provides the critical foundation for optimizing suspension performance, transforming engine power into superior track adhesion through precisely tuned spring rates.

ERS Double-Spring System Technology:

This main spring is part of Eibach's innovative ERS system, which uses a main and tender spring concept to deliver progressive suspension characteristics. 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. The main spring features a linear-rate characteristic that determines the final rate of the complete suspension system, allowing engineers and enthusiasts to fine-tune the balance between compliance and control.

Key Features:

• Linear-rate main spring for predictable, consistent performance
• Compatible with over 700 ERS spring components for virtually unlimited tuning combinations
• High spring travel and deflection capability with short mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Advanced corrosion protection through phosphating and epoxy coating
• Precision tolerances for exact fitment and performance
• Block resistance design prevents coil binding
• Part number imprinted directly on spring for easy identification of rate and dimensions
• Individual protective packaging to prevent damage during storage and shipping

Applications:

Ideal for racing applications where precise suspension tuning is critical, this main spring works in conjunction with Eibach tender springs and connecting plates to create a fully customizable suspension system. Use with helper springs to prevent spring looseness at full droop, or combine with tender springs to achieve specific initial and ending spring rates tailored to your vehicle's weight distribution and track conditions.
