What is a linear rate spring?

A linear rate spring means that the force it exerts increases proportionally to how much it is compressed. For every millimeter the spring is compressed, it pushes back with the same amount of force, providing predictable suspension behavior.

What does the 61mm ID refer to?

The 61mm ID refers to the inner diameter of the spring. This measurement is important for ensuring the spring fits correctly onto the shock absorber body or spring perch of a coilover assembly.

Is this spring sold individually or as a set?

This product listing is for a single AST Linear Race Spring. If you need a set, you will need to purchase multiple individual springs.

About this part

Product Details

You get one AST Linear Race Spring, measuring 130mm in length with a spring rate of 200 N/mm and a 61mm inner diameter. This spring is designed for performance applications, often used in coilover setups where precise suspension control is critical.

This spring is built for consistent performance. The linear rate means that for every millimeter the spring compresses, it exerts the same amount of force, providing predictable handling characteristics. The 61mm inner diameter is a common size for many aftermarket coilover systems, making it a versatile option for builds focused on track performance or spirited driving.
