The Tein Flex Z damper sub-assembly (BL9/BP9-F) is a replacement component for the Flex Z coilover line, intended to restore or maintain adjustable damping performance when refurbishing those suspension systems. It provides the necessary internal damper components compatible with Flex Z assemblies, letting owners service worn units without replacing the entire coilover where applicable.
