Eibach 1400.2530.0175 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. A properly tuned spring system provides the muscle needed to transform engine power to the track through optimum adhesion, balancing road contact with controlled body motion during cornering, acceleration, and braking.

This spring is part of Eibach's world-renowned ERS (Eibach Race Spring) system, which offers over 700 different single spring components that can be combined to create nearly unlimited suspension configurations. The ERS double-spring system relies on a Main and Tender spring concept that provides a softer initial rate when both springs are compressed together, then delivers a firmer ending rate once the tender spring closes completely. This Main spring features linear-rate characteristics and determines the final rate of your suspension system.

Key Features:

• High spring travel (deflection) delivers high end loads at short mounting lengths
• Superior block resistance for consistent performance
• Shot-peened surface treatment for enhanced fatigue resistance
• Exceptional dynamic durability ensures long component life
• Manufactured to precise tolerances for predictable behavior
• Premium corrosion protection through phosphating and epoxy coating
• Clearly imprinted with part number indicating spring rate and physical dimensions
• Compatible with Eibach Tender springs, Helper springs, and Connecting Plates for custom tuning

Designed for suspension engineers and performance enthusiasts who demand precision and flexibility, this XT Barrel Spring delivers the uncompromising performance required for competitive racing applications.
