Eibach 1800.300.0700S Silver Coilover Spring ID Off-Road Racing - 3.00

The Eibach 1800.300.0700S is a high-performance silver coilover spring designed for off-road and racing applications. Featuring a 3.00" inner diameter, this precision-engineered spring is part of Eibach's renowned ERS (Eibach Race Spring) system, providing the muscle needed to transform engine power into optimal track adhesion through precisely tuned suspension characteristics.

ERS Double Spring System:

This spring is compatible with Eibach's world-famous ERS double-spring system, which combines main and tender springs to create a sophisticated suspension solution. The system provides a softer initial rate when both springs compress together, then delivers a firmer ending rate once the tender spring closes completely. With over 700 different single spring components available, suspension engineers and enthusiasts can create nearly unlimited combinations for custom suspension tuning.

Key Features:

• Precision-engineered 3.00" inner diameter for racing and off-road applications
• Linear-rate characteristic for predictable suspension behavior
• High spring travel and deflection for maximum end loads at short mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Superior corrosion protection through phosphating and epoxy coating
• Block resistance to prevent coil binding
• Manufactured to precise tolerances for consistent performance
• Part number imprinted on spring indicating spring rate and physical dimensions
• High dynamic durability for extended component longevity
• Individual protective packaging to prevent damage

This spring can be used as a main spring in Eibach's modular system, allowing for custom suspension tuning when paired with tender or helper springs and connecting plates. The result is optimum balance between comfort and control, reducing body roll, squat, and dive during aggressive cornering, acceleration, and braking while maintaining road contact over irregular surfaces.
