Manley titanium double valve spring retainer, 1.625 diameter with +.100 offset, is a larger‑sized, lightweight retention choice for performance valvetrains. The +.100 sizing lets builders set specific installed heights while benefiting from reduced retainer mass. Intended for use with compatible springs and locks, it supports consistent valve control under elevated rpm and aggressive duty cycles.
