What is a linear spring rate?

A linear spring rate means that the force exerted by the spring increases proportionally to how much it is compressed. This offers a predictable and consistent feel during suspension travel.

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 or perch it is intended for.

Is this spring sold individually?

Yes, this product listing is for a single AST linear race spring. It is designed to be used as part of a set or as a replacement for one spring in a suspension system.

Product Details

AST is known for making well-built suspension components. This linear race spring is designed for performance applications where precise spring rates are critical. It measures 140mm in length with a spring rate of 80 Newtons per millimeter and a 61mm inner diameter.

This spring is a single unit, intended to be part of a custom coilover setup or as a replacement for an existing spring. The linear rate means that as the spring is compressed, the force increases proportionally, offering predictable handling characteristics. Its construction is focused on providing consistent performance under demanding conditions.
