What does a linear spring rate mean for my suspension?

A linear spring rate means the force the spring exerts increases directly with compression. This offers predictable handling characteristics, which is beneficial for performance driving and track use where consistent suspension feedback is important.

What is the inner diameter of this spring?

This AST Linear Race Spring has an inner diameter of 61mm. This is a common size for many aftermarket coilover systems, but it's always best to verify compatibility with your specific setup.

Is this spring sold as a set?

No, this AST Linear Race Spring is sold individually. If you are rebuilding or customizing a coilover setup, you will need to purchase the required number of springs separately.

About this part

Product Details

This is a single AST Linear Race Spring, measuring 200mm in length with a spring rate of 65 Newtons per millimeter and a 61mm inner diameter. These springs are designed for performance applications where precise suspension control is critical.

The linear spring rate means that as the spring is compressed, the force increases proportionally. This predictable behavior is essential for tuning suspension response, allowing for consistent handling during aggressive driving or track use. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for builders and racers looking to customize their setup. The 200mm length provides a good balance for achieving desired ride height and travel in many applications.
