Eibach 0800.250.0750 ERS Race Main Coilover Spring 8in Length 2.5in ID 750lb

The Eibach ERS (Eibach Race Spring) Main Spring is a precision-engineered linear-rate coilover spring designed for racing and high-performance suspension applications. This spring measures 8 inches in length with a 2.5-inch inner diameter and delivers a 750 lb/in spring rate, providing the firm, consistent response needed for serious track use and competitive motorsports.

ERS Double-Spring System:

This Main spring is part of Eibach's renowned ERS double-spring system, which combines Main and Tender springs to create a progressive suspension setup. The system provides a softer initial rate when both springs compress together, then transitions to the firmer Main spring rate once the Tender spring fully compresses. With over 700 different spring components available, the ERS system offers nearly unlimited tuning combinations for suspension engineers and enthusiasts alike.

Key Features:

• Linear-rate characteristic determines the final rate of the double-spring system
• Shot-peened surface treatment for superior fatigue resistance
• High spring travel and deflection capability at compact mounting lengths
• Phosphate and epoxy coating provides excellent corrosion protection
• Precision manufacturing with tight tolerances for consistent performance
• Part number imprinted directly on spring for easy identification of rate and dimensions
• High dynamic durability for extended component life in demanding racing conditions
• Compatible with Eibach connecting plates for Main/Tender spring configurations

Designed to reduce body roll, squat, and dive during cornering, acceleration, and braking while maintaining optimal tire contact with the road surface. Each spring is individually packaged for protection during shipping and storage.
