About this part

Product Details

This is a single AST Linear Race Spring, measuring 300mm in length with a spring rate of 25 N/mm and a 61mm inner diameter. These springs are built for performance applications where consistent spring rates are crucial for predictable handling.

The linear spring design means that as the spring is compressed, the force it exerts increases at a constant rate. This predictability is key for tuning suspension response, especially in racing or track day setups. The 61mm inner diameter is a common size for many coilover systems, making it a versatile option for custom builds or replacements. Its 300mm length and 25 N/mm rate offer a specific balance of ride height and stiffness that tuners often look for.
