Supertech Steel Retainers for all Honda/Acura B/H/K-series DOHC VTEC Engines that utilize dual valve springs.

These will work on all Supertech valve springs, OEM Valve Springs, and possibly other manufacturer aftermarket valve springs.

These retainers utilize OEM (7 Degree) Keepers and are compatible with Supertech Keepers.

16pc steel retainers set.

K-series note: these retainers are only compatible with K-series engines that are equipped with factory dual valve springs (02-mid 03 RSX Type-S and JDM K20A Type-R engines). Any K-series motor with factory single valve springs are incompatible with these retainers. You must convert to dual valve spring components before using these retainers, specifically dual valve spring seats, springs, and keepers.
