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 260 Newtons. This offers predictable suspension behavior.

What does the 61mm ID refer to?

The 61mm ID refers to the inner diameter of the spring. This is an important measurement to ensure the spring fits correctly onto the shock body or perch of your coilover system.

Is this spring sold individually or as a set?

This listing is for a single spring. If you are rebuilding a coilover system, you will typically need two springs per axle (front or rear) for proper suspension balance.

Product Details

This listing is for a single AST Linear Race Spring. You get one coilover spring, measuring 150mm in length with a spring rate of 260 Newtons per millimeter and an inner diameter of 61mm. These springs are designed for performance applications where a consistent spring rate is crucial for predictable handling.

Linear rate springs, like this one from AST, offer a straightforward spring rate that doesn't change significantly throughout its compression. This means the force required to compress the spring increases proportionally with the distance it's compressed. This predictability is highly valued in racing and performance driving, as it allows for more precise tuning of suspension characteristics. The 61mm inner diameter is a common size for many coilover systems, and the 150mm length offers a good balance for various ride height adjustments.

When building or rebuilding a performance suspension setup, choosing the right spring rate is key to achieving the desired handling balance. This AST spring is a solid option for those looking for a reliable, linear rate spring for their coilover system.
