Eibach 1200.2530.0150 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 coil spring is part of Eibach's renowned ERS (Eibach Race Spring) system, designed to optimize suspension performance through precise tuning and exceptional durability.

ERS Double Spring System:

This main spring works within Eibach's innovative double-spring configuration, combining with tender springs to create a progressive suspension response. The system delivers a softer initial rate when both springs compress together, then transitions to a firmer ending rate once the tender spring fully compresses. This main spring provides the linear-rate characteristic that determines the final rate of your suspension system, ensuring optimal balance between compliance and control during cornering, acceleration, and braking.

Key Features:

• Extreme travel design for maximum spring deflection at compact mounting lengths
• High block resistance prevents coil binding under extreme loads
• Shot-peened surface treatment for superior fatigue resistance
• Exceptional dynamic durability for extended component life
• Precision manufacturing with tight tolerances for consistent performance
• Advanced corrosion protection through phosphating and epoxy coating
• Clearly imprinted with part number, spring rate, and physical dimensions
• Compatible with over 700 ERS components for custom suspension tuning
• Individual protective packaging to prevent damage

Designed for professional race teams and serious enthusiasts, this XT barrel spring delivers the precise spring control needed to transform engine power into grip through optimum tire adhesion. The extreme travel design allows for greater suspension movement while maintaining consistent spring characteristics, making it ideal for rough track surfaces and high-speed applications.
