What is a linear spring rate?

A linear spring rate means that the force the spring exerts increases proportionally to how much it's compressed. For every millimeter the spring is compressed, it pushes back with a consistent amount of force, making its behavior predictable for tuning.

What does the 61mm ID refer to?

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

What is this spring typically used for?

This spring is designed for performance applications, often used in coilover systems for track cars or vehicles where precise suspension tuning is desired. The linear rate and specific dimensions are chosen for controlled handling.

About this part

Product Details

AST is known for making well-built suspension components. This Linear Race Spring is a prime example, offering a 130 N/mm spring rate in a 130mm length with 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 it exerts increases at a constant rate. This predictable behavior is essential for tuning suspension for specific track conditions or driving styles. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for builders looking to customize their setup.

When rebuilding or upgrading your coilovers, choosing the right spring rate is key to achieving the desired handling characteristics. This spring from AST offers a solid option for those seeking a specific rate for their performance build.
