What is a linear spring rate?

A linear spring rate means that for every unit of distance the spring is compressed, it exerts a consistent amount of force. This makes the suspension's response very predictable as it moves through its travel.

What does the 61mm ID refer to?

ID stands for Inner Diameter. This measurement indicates the diameter of the hole in the center of the spring, which is important for fitting it onto the shock absorber body or spring perch.

Can I use this spring with any coilover kit?

While the 61mm inner diameter is common, it's essential to verify that this specific spring dimension and length are compatible with your existing coilover system's specifications and intended application.

Product Details

This listing is for a single AST Linear Race Spring. It measures 80mm in length, has a spring rate of 240 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 spring force throughout their compression range, meaning the force increases predictably as the spring is compressed. This predictability is crucial for tuning suspension behavior, especially in racing or track day setups. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for builders and tuners looking to customize their suspension.

When selecting springs, consider how the rate and length will affect your vehicle's ride height and handling characteristics. This spring is a well-built component for those looking to fine-tune their suspension setup for improved performance.
