What does a linear spring rate mean for my suspension?

A linear spring rate means the force the spring exerts increases at a constant rate as it's compressed. This provides predictable and consistent suspension behavior, which is beneficial for performance tuning.

What is the inner diameter of this spring?

This AST Linear Race Spring has an inner diameter of 61mm. This is a common size for many aftermarket coilover systems.

Does this spring come with any hardware?

This product listing is for a single spring only. Any necessary hardware, such as spring perches or collars, would need to be sourced separately if not already part of your existing coilover assembly.

About this part

Product Details

This is a single AST Linear Race Spring, measuring 180mm in length with a spring rate of 100 N/mm and a 61mm inner diameter. These springs are designed for performance applications where precise suspension control is critical.

The linear spring rate means that for every millimeter the spring is compressed, it exerts the same amount of force. This predictable behavior is essential for tuning suspension for specific track conditions or driving styles. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for builders and racers looking to customize their setup. The 180mm length provides a good balance for achieving desired ride height and travel in many performance vehicles.
