What does a linear spring rate mean?

A linear spring rate means that the force the spring applies increases at a constant rate as it is compressed. For every millimeter the spring is compressed, the force increases by the specified N/mm value.

What is the inner diameter of this spring?

This spring has an inner diameter of 61mm. This is a common size for many coilover applications, but it's always best to measure your existing setup to ensure compatibility.

What is the spring rate of this AST spring?

This AST linear race spring has a spring rate of 30 N/mm. This value indicates how much force is required to compress the spring by one millimeter.

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 particular spring measures 200mm in length with a 61mm inner diameter and a spring rate of 30 N/mm. These specs make it suitable for applications where a consistent and predictable spring rate is crucial for handling and vehicle dynamics.

The linear spring design means that the force exerted by the spring increases proportionally with compression. This predictable behavior is favored in racing and performance setups for its ability to provide consistent feedback and control over a wide range of suspension travel. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for custom builds or replacements.
