A GSC Power Division beehive valve spring and titanium retainer kit for Subaru EJ257 engines, supplied for use with original equipment spring seats. This kit replaces valve springs and retainers to maintain valve control under higher lift and aggressive cam profiles; the beehive spring shape reduces mass at the retainer while the titanium retainers reduce reciprocating weight for more stable valvetrain operation.
