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 offers predictable handling and consistent feedback, which is beneficial for performance driving.

What is the inner diameter of this spring?

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

Is this spring sold individually or as a set?

This product listing is for a single AST Linear Race Spring. You will need to purchase multiple springs if you are replacing more than one on your vehicle.

About this part

Product Details

This is a single AST Linear Race Spring, measuring 100mm in length with a spring rate of 240 N/mm and a 61mm inner diameter. These springs are designed for performance applications where precise suspension control is crucial.

The linear spring rate means that as the spring is compressed, the force it exerts increases proportionally. This predictable behavior is favored in racing and performance setups for consistent handling and feedback. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for custom builds or replacements. Its 100mm length is also a standard dimension, fitting a variety of shock absorber bodies.
