Eibach 0800.225.0350 ERS 8" x 2.25" ID Race Coil-Over Spring

The Eibach 0800.225.0350 is an 8-inch long, 2.25-inch inner diameter coil-over race main spring designed for high-performance suspension applications. This precision-engineered spring is part of Eibach's renowned ERS (Eibach Race Spring) system, which allows racers and enthusiasts to create custom suspension setups by combining over 700 different spring components for nearly unlimited tuning possibilities.

ERS Main Spring Design:

This main spring features a linear-rate characteristic and serves as the foundation of Eibach's sophisticated double-spring system. When used with a tender spring, it provides a softer initial rate during combined compression, then transitions to a firmer ending rate once the tender spring fully closes. This progressive behavior optimizes both ride compliance over surface irregularities and body control during hard cornering, acceleration, and braking.

Key Features:

• 8-inch free length with 2.25-inch inner diameter for coil-over applications
• Linear-rate main spring characteristics for predictable suspension behavior
• Shot-peened surface treatment for enhanced fatigue resistance
• High-quality corrosion protection through phosphating and epoxy coating
• Exceptional spring travel and high end loads at compact mounting lengths
• Precision manufacturing with tight tolerances for consistent performance
• Superior dynamic durability and component longevity
• Clearly marked with part number indicating spring rate and dimensions
• Compatible with Eibach connecting plates for tender spring configuration
• Individual protective packaging for safe storage and handling

This race-spec spring delivers the precise suspension tuning needed to maximize traction and vehicle control in competitive motorsports applications, from road racing to autocross and track day events.
