What is a linear spring rate?

A linear spring rate means that for every millimeter the spring is compressed, the force required to compress it further increases by a consistent amount (95 N/mm in this case). This provides 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 to ensure the spring fits correctly onto the shock body or perch of your coilover system.

Is this spring sold individually or as a set?

This listing is for a single spring. If you are rebuilding or upgrading a coilover system, you will typically need to purchase multiple springs to match the vehicle's suspension setup.

About this part

Product Details

This listing is for a single AST Linear Race Spring. You get one spring measuring 300mm in length with a spring rate of 95 Newtons per millimeter and an inner diameter of 61mm.

These springs are built for performance applications where a consistent spring rate is crucial. The linear design means the spring rate stays the same throughout its compression, offering predictable handling and feedback. The 61mm inner diameter is a common size for many coilover systems, making it a popular choice for those looking to fine-tune their suspension setup. This spring is well-built and intended for track or race use where precise suspension response is needed.
