What is a linear spring rate?

A linear spring rate means that for every millimeter the spring is compressed, the force required to compress it further increases by a consistent amount (95 N/mm in this case). This provides predictable 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 needs to match the perch or shock body it will be installed on.

Is this spring sold individually or as a set?

This listing is for a single spring. If you are building or rebuilding a coilover assembly, you will need to purchase the appropriate number of springs for your application.

Product Details

This listing is for a single AST Linear Race Spring. You get one spring, measuring 200mm in length with a spring rate of 95 Newtons per millimeter and a 61mm inner diameter. These springs are designed for performance applications where a consistent spring rate is crucial for predictable handling.

Linear race springs like these offer a straightforward spring rate that doesn't change significantly throughout its compression. This predictability is valued in racing and performance setups because it allows for more precise tuning of suspension characteristics. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for builders and racers looking to customize their suspension.

When building or rebuilding coilovers, selecting the right spring rate is key to achieving the desired ride and handling. This 95 N/mm rate is a moderately stiff option, suitable for track use or spirited driving where improved body control is a priority. Remember that spring performance is also influenced by damping, so matching these springs with appropriate dampers is important for optimal results.
