AST astAST-70-65-64

The AST Helper Spring is a set of two auxiliary springs measuring 70mm long with a 65 N/mm rate and a 64mm inner diameter. Offered as a matched pair, these helper springs are intended for coilover assemblies requiring a 64mm ID and firmer auxiliary support. The 70mm length and higher 65 N/mm rate deliver consistent assistance when used in tandem with main springs during suspension tuning.
