What is the spring rate of this AST spring?

This AST Linear Race Spring has a spring rate of 220 N/mm. This indicates how much force is required to compress the spring by a certain amount, affecting the stiffness of the suspension.

What does 'linear' mean for a spring rate?

A linear spring rate means that the force the spring exerts increases in direct proportion to how much it is compressed. This provides predictable suspension response, which is beneficial for performance tuning.

What is the inner diameter of this spring?

The inner diameter of this AST spring is 61mm. This measurement is important to ensure it fits correctly onto the shock body or perch of your coilover assembly.

About this part

Product Details

This listing is for a single AST Linear Race Spring. It measures 120mm in length and has a spring rate of 220 N/mm, with an inner diameter of 61mm. These springs are designed for performance applications where precise suspension control is needed.

AST springs are known for their consistent performance. The linear rate means that as the spring is compressed, the force it exerts increases proportionally. This predictable behavior is crucial for tuning suspension for track use or spirited driving, helping to maintain tire contact with the road over bumps and during cornering. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for builders and tuners.
