What is the purpose of helper springs?

Helper springs are used in coilover setups to maintain preload on the main spring when the suspension is fully unloaded. This prevents the main spring from becoming loose and rattling, ensuring a more stable and predictable suspension response.

What material are these springs made from?

These AST helper springs are constructed from spring steel, chosen for its durability and ability to return to its original shape after compression.

Do these springs come with any hardware?

The provided product information does not specify if any additional hardware is included with the set of helper springs.

About this part

Product Details

These AST helper springs measure 70mm in length and have a spring rate of 65 N/mm, with an inner diameter of 75mm. They are designed to work with coilovers, providing a small amount of preload to keep the main spring seated when the suspension is fully extended. This helps prevent rattling and ensures the suspension behaves predictably, especially during aggressive driving or over rough terrain.

Constructed from well-built spring steel, these springs are made to withstand the constant stresses of suspension movement. The 75mm inner diameter is a common size for many coilover applications, making them a versatile option for those looking to fine-tune their suspension setup. Having a set of two means you can replace both sides of your vehicle for balanced performance.
