What is the purpose of a helper spring?

A helper spring is designed to maintain preload on the main spring of a coilover assembly. This ensures the main spring stays seated when the suspension is at full droop, preventing rattling or unseating.

What does the spring rate of 30 N/mm mean?

The 30 N/mm spring rate indicates the force required to compress the spring by one millimeter. This is a relatively light rate, meant to provide a gentle assist without significantly impacting the main spring's performance.

Are these springs sold individually?

No, this product is sold as a set of two helper springs. This quantity is typically needed to properly preload the main spring on a single coilover unit.

About this part

Product Details

This product includes a set of two AST Helper Springs. Each spring measures 65mm in length, has a spring rate of 30 N/mm, and an inner diameter of 61mm. These springs are designed to work with coilover systems, providing a small amount of preload to keep the main spring seated when the suspension is fully extended.

Helper springs are useful for maintaining proper coilover assembly, especially in applications where the suspension might droop significantly. They help prevent the main spring from rattling or becoming unseated during extreme articulation. The 30 N/mm rate offers a light assist, ensuring the main spring is always engaged without significantly altering the overall suspension feel.
