The AST Helper Spring is a set of two auxiliary springs measuring 110mm long with a 1 N/mm rate and a 61mm inner diameter. Sold as matched pairs, these long, very low-rate helper springs suit coilover assemblies needing 61mm ID compatibility and extended travel. The 110mm length pairs with a minimal 1 N/mm rate to provide subtle auxiliary support without significantly altering primary spring behavior.
