Eibach HELPER300T ERS Helper Spring 3.00 Inch Diameter 4.84 Inch Length

The Eibach HELPER300T is a precision-engineered helper spring designed to prevent the main spring from becoming loose in the spring seat when the suspension is unloaded or at full droop. Part of Eibach's renowned ERS (Eibach Race Spring) system, this helper spring features a 3.00-inch inside diameter, 4.84-inch length, and a minimal spring rate of 23 lbs/in.

Key Features:

• Flat-wire design for maximum travel and minimum block height
• Maintains spring position at full suspension droop with minimal interference to main spring rate
• Low spring rate (23 lbs/in) ensures no effect on suspension characteristics
• Covers up to 6 inches (150mm) of spring-to-perch gap
• Black powder-coated finish for corrosion resistance
• Individually tested for quality assurance
• Made from high-strength spring-steel alloy using advanced CNC winding process

Unlike tender springs which have specific rates for tuning, helper springs are designed with very little spring rate and serve solely to keep the main spring seated during suspension travel. This helper spring is ideal for coilover suspension setups in racing and high-performance applications where maintaining proper spring position is critical. Eibach's ISO 9001:2008 certified manufacturing ensures the highest quality and reliability, backed by a lifetime guarantee against sagging, rate change, or material failure.
