What is a linear spring rate and why is it important?

A linear spring rate means the spring's resistance to compression increases at a constant rate. This provides predictable suspension behavior, which is important for consistent handling and chassis feedback during performance driving.

What does the 61mm ID refer to?

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

Are these springs sold individually or as a set?

These AST Linear Race Springs are sold individually. If you are replacing or upgrading springs on a coilover system, you will typically need to purchase two springs per axle.

Product Details

Starting with a 60 N/mm spring rate and a 150mm length, these AST Linear Race Springs are built for performance applications where precise suspension control is key. The 61mm inner diameter ensures compatibility with many popular coilover setups, making them a solid choice for racers and serious track enthusiasts looking to fine-tune their vehicle's handling characteristics. These springs are designed to provide a consistent and predictable response under load, which is crucial for maintaining stability during aggressive driving maneuvers.

Constructed from high-tensile steel, these linear rate springs offer a well-built solution for upgrading or replacing existing coilover springs. The linear design means the spring rate remains constant throughout its compression, providing predictable suspension behavior that allows for better chassis feedback and control. This consistency is vital for setting up a vehicle for specific track conditions or driving styles, helping you achieve the optimal balance between ride comfort and track performance.
