The AST Helper Spring is a set of two short auxiliary springs measuring 65mm long with a 30 N/mm rate and a 75mm inner diameter. Supplied in pairs, these helper springs offer light auxiliary support for coilover-style assemblies where a larger inner diameter is needed. The 65mm length and specified rate help maintain consistent assistance when selected alongside primary springs during suspension setup.
