Eibach 1000.2530.0400 XT Barrel Extreme Travel Race Spring

The Eibach XT Barrel Extreme Travel Spring is engineered for racing applications where maximum suspension travel and precise tuning are critical. This barrel-style spring is part of Eibach's renowned ERS (Eibach Race Spring) system, designed to transform engine power into optimal track adhesion through superior suspension control.

ERS Double-Spring System Technology:

The ERS system utilizes a Main and Tender spring concept that delivers a softer initial rate when both springs compress together, then transitions to a firmer ending rate once the tender spring fully closes. This precise balance compensates for road irregularities while reducing body roll, squat, and dive during cornering, acceleration, and braking. With over 700 different spring components available, the system offers virtually unlimited tuning combinations.

Key Features:

• Barrel design provides high spring travel (deflection) and high end loads at short mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Superior corrosion protection through phosphating and epoxy coating
• Precision-manufactured with tight tolerances for consistent performance
• Block resistance for durability under extreme loads
• Part number imprinted on spring indicating spring rate and physical dimensions for easy identification
• Compatible with Eibach connecting plates for Main/Tender spring configurations
• High dynamic durability ensures extended component longevity
• Individual protective packaging to prevent damage

This extreme travel spring is ideal for professional racing teams and serious enthusiasts who demand the highest level of suspension performance and tunability.
