What is a linear spring rate?

A linear spring rate means that for every millimeter the spring is compressed, the force it exerts increases by a consistent amount (in this case, 110 Newtons per millimeter). This provides predictable and progressive 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 absorber body or spring perch of your coilover assembly.

What is the advantage of a 180mm length spring?

The 180mm length is a common size for performance coilovers, offering a good balance between travel and packaging. It's often chosen to work with specific shock absorber lengths and desired ride heights.

About this part

Product Details

When you're rebuilding your coilover setup or looking to fine-tune your suspension for track use, selecting the right spring rate is crucial. This AST Linear Race Spring is designed for performance applications where precise control and consistent damping are key. Its linear rate means the spring force increases proportionally with compression, offering predictable handling characteristics.

This particular spring measures 180mm in length and has a spring rate of 110 N/mm, with a 61mm inner diameter. These dimensions are common for many performance coilover systems, allowing for a direct replacement or upgrade. The well-built construction ensures it can handle the rigors of spirited driving and repeated compression cycles without losing its intended performance.
