What is a linear spring rate?

A linear spring rate means that for every unit of force applied, the spring compresses by a consistent amount. This results in predictable suspension behavior, which is often preferred for performance driving where precise control is important.

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 will properly fit onto the shock absorber body or perch of your coilover assembly.

Can I mix and match these springs with other brands?

While the 61mm inner diameter is a common size, it's best to use springs designed for your specific coilover system. Mixing brands or types may affect suspension geometry and performance. Always refer to the coilover manufacturer's recommendations.

Product Details

This is a single AST Linear Race Spring, measuring 130mm in length with a spring rate of 360 N/mm and a 61mm inner diameter. These springs are designed for performance applications, often used in coilover setups where precise suspension control is critical. The linear rate means the spring compresses at a consistent rate under load, providing predictable handling characteristics.

Crafted for demanding use, these springs are built to withstand the rigors of track driving or spirited road use. The 360 N/mm rate offers a firm ride, which can improve cornering stability and responsiveness by reducing body roll. The 61mm inner diameter is a common size for many aftermarket coilover systems, making it a versatile option for builders and tuners looking to fine-tune their suspension.

When building or rebuilding coilovers, selecting the right spring rate is crucial for achieving the desired ride and handling. This spring is a solid option for those seeking a specific, firm setup. Always ensure compatibility with your existing coilover bodies or intended application before purchase.
