Eibach 1400.2530.0200 XT Barrel Spring Extreme Travel Race Main Spring

The Eibach XT (Extreme Travel) Barrel Spring is a high-performance race main spring engineered for motorsport applications requiring exceptional suspension travel and precise tuning capabilities. This spring is part of Eibach's renowned ERS (Eibach Race Spring) system, designed to optimize traction and handling through proper suspension geometry control.

ERS Double Spring System:

The XT spring functions as the main component in Eibach's innovative double-spring system, which combines main and tender springs to achieve optimal suspension 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 compresses. This linear-rate main spring determines the final rate of the complete spring system, allowing engineers to fine-tune suspension response for cornering, acceleration, and braking while maintaining tire contact through road irregularities.

Key Features:

• Extreme travel design delivers high deflection and maximum end loads at compact mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance and longevity
• Precision manufacturing with tight tolerances ensures consistent performance
• Block resistance prevents coil binding under extreme compression
• Advanced corrosion protection through phosphating and epoxy coating
• Clearly imprinted with part number indicating spring rate and physical dimensions for easy identification
• Compatible with Eibach connecting plates and tender/helper springs for customized spring combinations
• Individual protective packaging to prevent damage during storage and installation

Designed for racing applications where suspension tuning precision directly impacts track performance, this XT barrel spring delivers the durability and consistency demanded by professional motorsport teams and serious enthusiasts.
