Eibach HELPER70 ERS Helper Spring 2.75 in ID 3.94 in Length 17 lbs/in Rate

The Eibach HELPER70 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. This helper spring features a flat-wire design for minimal interference with main spring rate and travel to maintain spring position at full suspension droop.

Key Specifications:

• Inside Diameter: 2.75 inches
• Length: 3.94 inches
• Spring Rate: 17 lbs/in
• Gunmetal powder-coated finish for corrosion resistance
• Sold individually (single spring)

Features and Benefits:

• Unlike tender springs, helper springs have very little spring rate and therefore have no effect on the suspension characteristics of the vehicle
• Covers up to 2 inches (50mm) of spring-to-perch gap
• Coiled from flat wire for better travel and reduced block height
• Built using high-quality steel with powder coating to effectively resist corrosion
• Part of Eibach's ERS (Eibach Race Spring) system for professional suspension tuning

The Eibach ERS Helper Spring allows suspension engineers and weekend racers to create the perfect combination of spring rates for the ultimate suspension setup. This universal helper spring is ideal for coilover systems in racing, off-road, and high-performance street applications where suspension droop and spring retention are critical.
