About this part

Product Details

AST is known for making well-built suspension components. This linear race spring is designed for performance applications where precise spring rates are critical. It measures 140mm in length with a 300 N/mm spring rate and a 61mm inner diameter, making it suitable for custom coilover builds or as a replacement for existing race springs.

The linear spring design means that as the spring is compressed, the force it exerts increases at a constant rate. This predictable behavior is important for tuning suspension for track use. The 61mm inner diameter is a common size for many performance coilovers, and the 140mm length offers a good balance for stroke and packaging in many applications.
