Eibach 1400.2530.0225 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. This spring is part of Eibach's renowned ERS (Eibach Race Spring) system, which offers nearly unlimited combination possibilities by pairing main springs with tender or helper springs to achieve optimal suspension characteristics.

Key Features:

• High spring travel (deflection) with exceptional end loads at short mounting lengths
• Linear-rate characteristic that determines the final rate when used in double-spring systems
• Surface treated through shot-peening for enhanced fatigue resistance
• Superior corrosion protection via phosphating and epoxy coating
• Precise manufacturing tolerances for consistent performance
• Block resistance for extreme compression scenarios
• Part number imprinted on spring for easy identification of spring rate and dimensions
• High dynamic durability ensures extended component longevity
• Individual protective packaging to prevent shipping damage

This main spring serves as the primary load-bearing component in the ERS double-spring system. When combined with a tender spring via connecting plates, it provides a softer initial rate during both springs' compression, then transitions to a firmer ending rate once the tender spring fully compresses. This tuning flexibility allows suspension engineers and racing enthusiasts to precisely balance road contact and body control during cornering, acceleration, and braking. The XT barrel design is specifically engineered for extreme travel applications where maximum suspension articulation is required.
