What is a linear spring rate?

A linear spring rate means that for every inch the spring is compressed, the force required to compress it further increases by a consistent amount. This provides predictable suspension behavior, which is often preferred in racing and performance driving.

What does the 61mm ID refer to?

The 61mm ID refers to the inner diameter of the spring, which is 61 millimeters. This measurement is important for ensuring the spring will fit correctly onto the shock body or perch of your coilover system.

Can I mix and match these springs with other brands?

While the 61mm inner diameter is a common size, it's best to ensure that the spring's length and rate are compatible with your specific coilover system's design and intended use. Mixing springs from different manufacturers without careful consideration could affect suspension balance and performance.

About this part

Product Details

This listing is for a single AST Linear Race Spring. You get one spring, measuring 130mm in length with a spring rate of 110 N/mm and a 61mm inner diameter. These springs are designed for performance applications where a consistent and predictable spring rate is crucial for handling and control.

Linear rate springs like these offer a straightforward spring behavior, meaning the force increases proportionally with compression. This predictability is valued in racing and performance driving for tuning suspension response. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for builders or those looking to replace individual springs in their existing setup. The 130mm length and 110 N/mm rate are specific choices for achieving a particular ride height and stiffness balance.
