Eibach HELPER300 Helper Spring for ERS Suspension Systems

The Eibach HELPER300 is a specialized helper spring designed to prevent the main spring from becoming loose in the spring seat when the wheel is at full droop. Unlike tender springs, helper springs have minimal spring rate and therefore do not affect the suspension characteristics of your vehicle. This component can accommodate up to 50mm of spring-to-perch gap, making it an essential element in Eibach's renowned ERS (Eibach Race Spring) double-spring suspension systems.

Key Features:

• Minimal spring rate design ensures no impact on suspension performance
• Prevents main spring separation at full droop
• Accommodates up to 50mm spring-to-perch gap
• Surface treated through shot-peening for enhanced durability
• High-quality corrosion protection with phosphating and epoxy coating
• Precision manufactured with tight tolerances
• Imprinted with part number for easy identification
• Individual protective packaging

Eibach's ERS system uses a main and tender spring concept that provides a softer initial rate when both springs compress together, then delivers a firmer ending rate once the tender spring fully closes. The helper spring complements this system by maintaining proper spring positioning throughout the full range of suspension travel, ensuring consistent performance during racing and performance driving applications.
