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. This provides predictable suspension behavior.

What does the 160 N/mm rate mean for my car?

A 160 N/mm spring rate is considered moderately stiff. It will help reduce body roll during cornering and improve the responsiveness of your suspension, making it suitable for performance driving.

Is this spring sold individually or as a set?

This listing is for a single spring. If you are replacing or upgrading suspension components, ensure you purchase the correct quantity needed for your application.

About this part

Product Details

What you get with this listing is a single AST Linear Race Spring. It measures 80mm in length, has a spring rate of 160 Newtons per millimeter, and an inner diameter of 61mm. This spring is designed for performance applications where a specific, consistent spring rate is crucial for handling and suspension response.

These linear springs are built to maintain their rate throughout their travel, which helps provide predictable suspension behavior. The 160 N/mm rate is a moderately stiff rate, often chosen for track cars or performance street setups where improved body control and reduced roll during cornering are desired. The 61mm inner diameter is a common size for many coilover systems, making it a potential replacement or upgrade part.
