Eibach 1200.2530.0225 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 transform engine power into track grip through optimized suspension tuning.

ERS Double Spring System:

This main spring integrates seamlessly into Eibach's modular ERS double-spring system, which combines main and tender springs to achieve superior performance 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. With over 700 individual spring components available, the ERS system offers virtually unlimited tuning combinations for professional race teams and enthusiast tuners alike.

Key Features:

• Linear-rate characteristics that determine the final rate of your suspension system
• High spring travel (deflection) delivering maximum end loads at compact mounting lengths
• Block resistance for progressive bottoming control
• Shot-peened surface treatment for enhanced fatigue resistance
• Exceptional dynamic durability for extended service life under racing conditions
• Precision manufacturing with tight tolerances for consistent performance
• Advanced corrosion protection through phosphating and epoxy coating
• Clearly imprinted part number indicating spring rate and physical dimensions

Compatible with Eibach connecting plates (inside and outside diameter options) for integration with tender springs, and can be used with helper springs to prevent spring unseating at full droop. Each spring is individually packaged to ensure protection during storage and installation.
