What is a linear spring rate?

A linear spring rate means that for every millimeter the spring is compressed, its resistance increases by the same amount (95 N/mm in this case). This provides predictable and consistent suspension behavior.

What does the 61mm ID refer to?

ID stands for Inner Diameter. The 61mm measurement indicates the diameter of the hole in the center of the spring, which is important for fitting onto your coilover shock body or perch.

Can I buy a pair of these springs?

This listing is for a single spring. If you need a pair or a full set for your vehicle, you will need to adjust the quantity accordingly or check for a multi-spring package if available.

About this part

Product Details

This listing is for a single AST Linear Race Spring. You get one spring measuring 180mm in length with a spring rate of 95 Newtons per millimeter and a 61mm inner diameter. These springs are designed for performance applications where precise suspension control is needed.

Crafted for durability and consistent performance, this spring is a solid option for rebuilding or upgrading your coilovers. The linear rate means the spring's resistance increases uniformly as it's compressed, offering predictable handling characteristics. Its 61mm inner diameter is a common size for many coilover systems, making it a versatile choice for custom builds or replacements.
