Eibach 1400.250.0200 ERS 14" x 2.5" ID Coil-Over Race Spring

The Eibach 1400.250.0200 is a high-performance race main spring designed for coil-over suspension systems, measuring 14 inches in length with a 2.5-inch inner diameter. This precision-engineered component is part of Eibach's renowned ERS (Eibach Race Spring) system, providing racers and enthusiasts with the ability to fine-tune suspension characteristics for optimal track performance.

ERS Double Spring System Technology:

This main spring is designed to work within Eibach's ERS double-spring system, which combines main and tender springs to create a progressive suspension response. The system provides a softer initial rate when both springs compress together, then transitions to a firmer ending rate once the tender spring fully compresses. With over 700 different spring components available, the ERS system offers nearly unlimited tuning combinations for precise suspension optimization.

Key Features:

• Linear-rate main spring that determines the final rate of the suspension system
• Shot-peened surface treatment for enhanced fatigue resistance
• High spring travel and deflection capacity at short mounting lengths
• Superior block resistance for consistent performance
• Precision manufacturing with tight tolerances for reliable operation
• Advanced corrosion protection through phosphating and epoxy coating
• Clearly imprinted with part number indicating spring rate and physical dimensions
• Exceptional dynamic durability for extended component life
• Individual protective packaging to prevent damage during storage and shipping

This main spring is ideal for racers and performance enthusiasts seeking to optimize vehicle dynamics by reducing body roll, squat, and dive during cornering, acceleration, and braking while maintaining adequate compliance for track irregularities. Compatible with Eibach's tender springs, helper springs, and connecting plates for complete suspension customization.
