Eibach 1800.300.0600S Silver Coilover Spring ID Off-Road Racing - 3.00

The Eibach 1800.300.0600S is a silver coilover spring for off-road racing, part of the Eibach Silver Coilover Spring ID Off-Road Racing line. This variant is the 3.00 version. Eibach's ERS (double spring) system is designed to balance ride compliance and body control, helping keep the wheels in contact with the surface while limiting body roll, squat and dive during cornering, acceleration and braking.

How the ERS System Works:

• Main spring: Linear-rate spring that determines the final rate of the system.
• Tender spring: Determines the initial rate of the system. Tender springs are available in linear-rate and progressive-rate characteristics. The system starts softer while both springs compress together, then gives a firmer ending rate once the tender spring closes completely.
• Helper spring: Keeps the main spring from becoming loose in the spring seat at full wheel droop. It has very little spring rate, so it does not affect suspension characteristics, and it can cover up to 50mm of spring-to-perch gap.
• Connecting plates: Join the main and tender springs. Eibach offers inside and outside diameter plates to suit the dimensions and function of the damper used.

Key Features:

• Can be combined with standard spring components to create a wide range of setups
• High spring travel (deflection) and high end loads at short mounting lengths
• Block resistance
• Surface treated through shot-peening
• High dynamic durability for long component life
• Precise tolerances
• Corrosion protection by phosphating and epoxy coating
• Individual protective packaging
• Imprinted with the part number, which indicates spring rate and physical dimensions, for easy identification

Whether you are a suspension engineer or a weekend enthusiast, this Eibach coilover spring offers a flexible, durable way to tune your off-road racing suspension.
