Eibach 1400.2530.0150 XT Barrel Spring - Extreme Travel Race Main Spring

The Eibach XT (Extreme Travel) Barrel Spring is a high-performance race main spring engineered for demanding motorsport applications. This precision-manufactured spring is part of Eibach's renowned ERS (Eibach Race Spring) system, designed to optimize suspension performance by transforming engine power into superior track adhesion through a perfectly balanced spring setup.

ERS Double Spring System:

This main spring integrates seamlessly into Eibach's versatile ERS double-spring configuration, which combines main and tender springs to deliver a sophisticated two-stage rate characteristic. 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. With over 700 individual spring components available in the ERS lineup, suspension engineers can create virtually unlimited combinations tailored to specific vehicle dynamics and track conditions.

Key Features:

• Linear-rate characteristic determines the final rate of the suspension system
• Extreme travel design delivers high spring deflection and elevated end loads despite short mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Block resistance prevents coil binding under extreme compression
• Precision tolerances ensure consistent performance and predictable handling
• Superior corrosion protection through phosphating and epoxy coating
• High dynamic durability extends component longevity in race conditions
• Clearly imprinted with part number indicating spring rate and physical dimensions for easy identification
• Compatible with Eibach connecting plates for main/tender spring configurations
• Individual protective packaging prevents damage during storage and transport

Ideal for professional racing teams and serious enthusiasts who demand precise suspension tuning to reduce body roll, squat, and dive during aggressive cornering, acceleration, and braking while maintaining optimal tire contact with the track surface.
