TITANIUM VALVE SPRING RETAINERS -

APE valve spring retainers are machined from aircraft quality titanium bar stock in the APE plant on the latest state of the art computerized CNC machinery.CNC machining allows us to offer such advantages as bored taper keeper holes for exact keeper fit. Special gauging fixtures allow dimensions to be held close to provide exact installed heights when assembling the cylinder head. APE titanium retainers are shorter than stock to provide additional retainer to valve guide clearance for high lift cams. APE is the only manufacturer of motorcycle retainers that also builds cylinder heads. We know how they have to fit, how they have to clear the bucket, etc. No other manufacturer can offer this expertise. You might think this extra precision is expensive.The fact that we are the manufacturer allows us to provide these super precision retainers at a price everyone can afford. See the chart above for applications.

NO MATTER WHO BUILDS YOUR CYLINDER HEAD, INSIST THAT THEY USE APE TITANIUM RETAINERS.

You'll never see this happen with an APE titanium retainer...
