About this part

Product Details

AST is known for making well-built suspension components, and these Linear Race Springs are no exception. They are designed for performance applications where consistent spring rates are critical for predictable handling. This particular spring measures 250mm in length with a 30 N/mm spring rate and a 61mm inner diameter, making it a solid option for custom coilover builds or as a replacement for existing race-oriented setups.

The linear spring rate means that for every millimeter the spring is compressed, the force increases by a consistent amount (30 Newtons per millimeter in this case). This predictability is key for tuning suspension performance, especially during hard cornering or braking. The 61mm inner diameter is a common size for many coilover shock bodies, but it's always a good idea to measure your existing setup to ensure compatibility.
