What is a linear spring rate?

A linear spring rate means that for every millimeter the spring is compressed, it exerts the same amount of force. This results in predictable suspension behavior, which is beneficial for performance driving.

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 fits correctly onto the shock absorber body of your coilover system.

What is the advantage of a 130mm spring length?

The 130mm length allows for specific tuning of ride height and suspension travel. When combined with the correct damper, it helps achieve the desired stance and performance characteristics for your vehicle.

About this part

Product Details

AST is known for making performance suspension components. This linear race spring is designed for track-focused setups where precise spring rates are crucial. It measures 130mm in length with a 60 N/mm spring rate and a 61mm inner diameter, making it suitable for many coilover applications that require a specific, consistent rate for predictable handling.

Linear springs like this one offer a consistent force increase throughout their travel. This means the suspension behaves predictably under load, which is essential for competitive driving. The 61mm ID is a common size for many performance coilover bodies, and the 130mm length helps achieve specific ride heights and suspension travel when paired with appropriate dampers.
