Eibach 1000.188.0300 Race Main Spring 1.88" ID Midget Legend

The Eibach 1000.188.0300 is a high-performance race main spring designed for Midget and Legend car racing applications. With a 1.88" inner diameter, this precision-engineered component is part of Eibach's renowned ERS (Eibach Race Spring) system, delivering the muscle needed to transform engine power into optimal track adhesion through superior suspension tuning.

ERS Double Spring System Technology:

This main spring integrates seamlessly into Eibach's ERS double-spring system, which combines main and tender springs to provide exceptional suspension flexibility. The system delivers 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 single spring components available in the ERS lineup, suspension engineers can create virtually unlimited combinations for precise tuning.

Key Features:

• Linear-rate characteristic determines final system rate
• 1.88" inner diameter for Midget and Legend car applications
• High spring travel and deflection for maximum end loads at short mounting lengths
• Shot-peened surface treatment for enhanced durability
• Superior corrosion protection through phosphating and epoxy coating
• Precision manufacturing with tight tolerances for consistent performance
• Part number imprinted directly on spring for easy identification
• High dynamic durability for extended component longevity
• Block resistance for extreme racing conditions

Application Notes:

As a main spring, this component works in conjunction with tender springs (which determine initial rate) and helper springs (which prevent spring looseness at full droop). Connecting plates are used to join main and tender springs. This modular approach allows for precise suspension tuning to balance road contact compensation with the firmness needed to reduce body roll, squat, and dive during cornering, acceleration, and braking.

Each spring comes individually packaged with protective coating and clear part number identification for easy installation and inventory management.
