What is a linear spring rate?

A linear spring rate means the force required to compress the spring increases at a constant rate. For every millimeter the spring is compressed, the force increases by 240 Newtons. This provides predictable suspension behavior.

What does the 61mm ID refer to?

ID stands for Inner Diameter. The 61mm measurement indicates the diameter of the hole in the center of the spring. This is important for ensuring it fits correctly onto your coilover shock body or perch.

Is this spring sold individually?

Yes, this product listing is for a single linear race spring. If you are rebuilding a full set of coilovers, you will need to purchase multiple springs to match your vehicle's suspension setup.

About this part

Product Details

AST is known for making well-built suspension components. This linear race spring is a single unit designed for performance applications. It measures 130mm in length and has a spring rate of 240 Newtons per millimeter, with a 61mm inner diameter. This specific spring rate is often chosen for track-focused setups where a firmer suspension response is desired.

These springs are built for consistent performance. The linear rate means the spring's resistance increases predictably as it's compressed, which is crucial for maintaining control during hard cornering and braking. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for builders looking to tune their suspension.
