Supertech 5.5mm 7 Degree Valve Keepers for B/K Series

Supertech 5.5mm 7 Degree Valve Keepers - Honda/Acura B/D/F/H/K Series

If you've got the head apart on your Honda or Acura, doing springs, retainers, valves, or a full rebuild, don't reuse the old valve keepers. These are Supertech's 5.5mm, 7-degree keepers, the tiny locks that wedge your valve spring and retainer onto each valve stem and hold the whole valvetrain together. You get 32 of them, which is two per valve for a full 16-valve head, so one pack does the whole engine. They're cheap, but they're doing one of the most important jobs in there, and fresh ones are exactly what you want going back in next to your new parts.

Small Part, Huge Responsibility

Here's what these actually do, because it's easy to overlook them. Each pair of keepers drops into the groove on your valve stem and locks the retainer in place, which is what holds your valve spring under tension and keeps the valve hung where it belongs. That little pair is the only thing stopping a valve from dropping into the cylinder, and on a Honda that loves to rev, S2000s spinning toward 9,000 rpm, built B and K motors living up top, those keepers are getting hammered thousands of times a minute. If one ever lets go, the valve drops and the engine's done, just like that. That's why you don't cut corners here and why you don't reuse tired old keepers on a fresh build.

7-Degree Lock, 5.5mm Stem, Plays Nice With Your Retainers

These run a 7-degree taper, which is the angle that wedges the keeper tight against the retainer, and they're cut for 5.5mm valve stems, the size used across these B, D, F, H, and K series engines. Supertech machined them for a precise, repeatable fit, and they work with both factory and aftermarket 5.5mm valves, plus most OEM and aftermarket retainers. So whether you're keeping it mostly stock or you've already got upgraded springs and retainers on the bench, these slot right into the setup. One thing worth checking if you're running aftermarket valves: confirm your valves use a 5.5mm stem and a 7-degree lock groove before you order, since that's what these are built for.

When You'd Grab These

You're not pulling a head apart just to swap keepers, so you're usually here for something bigger, fresh valve springs and retainers, aftermarket valves, a valve job, or a full head refresh. Whatever brought you in, this is the moment to put new keepers in too. They're a few bucks, they're already exposed with everything apart, and the last thing you want is a worn keeper failing later and forcing you back into a job you just finished. New hardware on a fresh head is just smart insurance.
