What is the spring rate of this AST spring?

This AST Linear Race Spring has a spring rate of 320 Newtons per millimeter (N/mm). This indicates how much force is required to compress the spring by a certain distance.

What does 'linear rate' mean for a spring?

A linear rate spring means that the force it exerts increases at a constant rate as it's compressed. This provides a predictable and consistent 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 is a common size for many aftermarket coilover systems, but it's always best to verify compatibility with your specific setup.

Product Details

This listing is for a single AST Linear Race Spring. It measures 130mm in length, has a spring rate of 320 Newtons per millimeter, and an inner diameter of 61mm. These springs are designed for performance applications where precise suspension control is needed.

Linear rate springs offer a consistent force increase as they are compressed, meaning the suspension response is predictable throughout its travel. This makes them a popular choice for track cars or performance street setups where tuning the suspension's behavior is key. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for builders or those looking to replace worn-out springs.

When selecting springs, consider how the rate will affect your vehicle's handling. A stiffer spring like this 320 N/mm rate will reduce body roll and improve responsiveness, but it can also make the ride firmer. Ensure this spring rate and diameter are compatible with your existing coilover hardware or intended build.
