What is a linear spring rate?

A linear spring rate means the force required to compress the spring increases in direct proportion to how much it's compressed. This offers predictable suspension behavior, unlike progressive springs where the rate changes.

What does the 61mm ID refer to?

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

Can I mix and match spring rates?

While it's possible, it's generally recommended to use matched spring rates on the same axle for consistent handling and balance. Using different rates can lead to unpredictable vehicle dynamics.

About this part

Product Details

This is a single AST Linear Race Spring. It measures 250mm in length, has a spring rate of 110 N/mm, and an inner diameter of 61mm. These springs are designed for performance applications where a consistent spring rate is crucial for predictable handling.

Linear rate springs offer a straightforward spring rate that doesn't change with compression. This means the force required to compress the spring increases in direct proportion to how much it's compressed. This predictability is valued in racing and performance setups for consistent suspension response. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for builds or replacements.

When replacing coilover springs, it's important to ensure you have the correct inner diameter and length to match your existing coilover bodies. Always refer to your coilover manufacturer's specifications to confirm compatibility.
