What is a linear spring rate?

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

What does the 61mm ID refer to?

ID stands for Inner Diameter. This measurement is crucial for ensuring the spring will fit correctly onto the shock absorber body or spring perch of your coilover system. Always verify this dimension matches your existing or intended setup.

What is this spring typically used for?

Linear race springs are commonly used in performance and racing applications where consistent and predictable suspension response is important. They are often found in custom coilover builds or as replacements for performance-oriented suspension kits.

About this part

Product Details

AST is a well-known name in the performance suspension world, and these linear race springs are a testament to that. This specific spring is designed for applications where precise spring rates and consistent performance are critical. It measures 300mm in length with a spring rate of 110 Newtons per millimeter and has an inner diameter of 61mm, making it a solid choice for many coilover setups.

Linear springs like these offer a predictable and consistent spring rate throughout their travel. This means that as the suspension compresses, the force required to compress it further increases in a straight line. This predictability is highly valued in racing and performance driving, as it allows for more accurate tuning of suspension geometry and handling characteristics. The well-built construction ensures it can handle the demands of spirited driving.
