The Supertech titanium retainer for H1000 series springs is listed for Honda K24Z7 applications with 7° seat angle (OEM is 6°). It replaces the factory retainer to secure spring and keeper, preserving installed height and valvetrain geometry for K24Z7 heads while noting the retainer uses a 7° configuration rather than the OEM 6° specification where that change is intended.
