AST Linear Race Springs - 150mm Length x 280 N/mm Rate x 61mm ID - Single

Starting with a 61mm inner diameter and a spring rate of 280 N/mm, these AST Linear Race Springs are built for performance applications where precise suspension control is key. The 150mm length offers a specific travel and compression characteristic, making it suitable for custom coilover setups or as a replacement for worn-out springs on performance vehicles. These springs are designed to provide a consistent force throughout their compression range, which helps maintain predictable handling and grip, especially during spirited driving or track use.

Crafted from high-tensile steel, these springs are made to withstand the rigors of demanding use while maintaining their intended spring rate over time. The linear rate means that for every millimeter the spring is compressed, it exerts the same amount of force, allowing for more straightforward suspension tuning and a more direct feel from your vehicle's suspension. This predictability is crucial for drivers who need to understand and rely on their car's handling characteristics.

This is a single spring, so be sure to order the correct quantity needed for your specific application. They are often used in conjunction with other suspension components to achieve a desired ride height and stiffness. Always refer to your vehicle's service manual or a qualified mechanic for installation guidance and to ensure compatibility with your existing coilover setup.
