Eibach 1200.2530.0250 XT Barrel Spring Extreme Travel Race Main Spring

The Eibach XT (Extreme Travel) Barrel Spring is a precision-engineered race main spring designed for high-performance suspension systems. Part of Eibach's renowned ERS (Eibach Race Spring) system, this linear-rate main spring provides the foundation for optimizing vehicle dynamics during racing conditions.

ERS Double Spring System:

This main spring integrates seamlessly into Eibach's world-famous ERS double-spring system, which combines main and tender springs to deliver superior suspension control. 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 different spring components available, engineers and enthusiasts can create nearly unlimited suspension combinations tailored to specific track conditions and vehicle requirements.

Key Features:

• Linear-rate characteristic that determines the final rate of the suspension system
• High spring travel (deflection) capability with exceptional end loads at short mounting lengths
• Block resistance for consistent performance under extreme conditions
• Shot-peened surface treatment for enhanced fatigue resistance
• Superior dynamic durability ensuring extended component longevity
• Manufactured to precise tolerances for predictable performance
• Advanced corrosion protection through phosphating and epoxy coating
• Clearly imprinted with part number indicating spring rate and physical dimensions

Professional Engineering:

A properly tuned spring system transforms engine power to the track through optimum tire adhesion. The suspension must balance being soft enough to compensate for road irregularities while remaining firm enough to reduce body roll, squat, and dive during cornering, acceleration, and braking. This XT Barrel Spring delivers that critical balance for competitive racing applications.

Compatible with Eibach connecting plates for pairing with tender springs, and can be used with helper springs to prevent spring looseness at full droop positions up to 50mm of spring-to-perch gap.
