What is a linear spring rate?

A linear spring rate means that for every millimeter the spring is compressed, the force it exerts increases by a consistent amount. This provides predictable suspension behavior, which is important for performance tuning.

What does the 61mm ID refer to?

The 61mm ID refers to the inner diameter of the spring. This measurement is important for ensuring the spring will fit correctly onto the shock body or perch of your coilover assembly.

Can I use this spring with any coilover?

While the 61mm inner diameter is common, it's essential to verify that this spring's dimensions and rate are compatible with your specific coilover system's design and intended use.

About this part

Product Details

This listing is for a single AST Linear Race Spring. You get one spring with a 200mm length, a spring rate of 100 N/mm, and an inner diameter of 61mm. These springs are designed for performance applications where a consistent spring rate is crucial for predictable handling.

Linear race springs like these are built to maintain their specified rate throughout their travel. This means that as the suspension compresses, the force increases in a direct, linear relationship. This predictability is key for tuning suspension for track use or spirited driving, allowing for more precise adjustments to ride height and cornering characteristics. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for builders and tuners.
