Eibach 1400.300.0300S Silver Coilover Spring ID Off-Road Racing - 3.00

The Eibach 1400.300.0300S is a precision-engineered off-road coilover spring with a 3.00" inner diameter, designed for racing and high-performance suspension applications. Part of Eibach's renowned ERS (Eibach Race Spring) system, this silver-finished spring delivers the precision tuning needed to transform engine power into optimal track adhesion through superior suspension control.

ERS Double-Spring System Technology:

This spring is compatible with Eibach's innovative ERS double-spring system, which combines Main and Tender spring components to create a sophisticated two-stage rate system. The setup provides a softer initial rate when both springs compress together, then transitions to a firmer ending rate once the tender spring fully closes. With over 700 different spring components available in the ERS lineup, suspension engineers and enthusiasts can create nearly unlimited tuning combinations for precise handling characteristics.

Key Features:

• 3.00" inner diameter for compatibility with standard coilover dampers
• Linear-rate characteristic for predictable suspension response
• High spring travel and deflection for maximum end loads at short mounting lengths
• Shot-peened surface treatment for enhanced fatigue resistance
• Phosphate and epoxy coating for superior corrosion protection
• Precision manufacturing with tight tolerances for consistent performance
• Part number imprinted on spring indicates spring rate and physical dimensions for easy identification
• High dynamic durability ensures extended component longevity under racing conditions
• Block resistance design prevents spring damage at full compression

Compatible with Eibach connecting plates for Main/Tender spring setups and Helper springs to prevent spring looseness at full droop extension. Individual protective packaging ensures the spring arrives ready for installation.
