910 shaft adapter

I am trying to change out my stock shafts on my 910d3 and 910f, where can i get the adapter sleeve, the real ones, not the aftermoarket ones?

If you just want authentic Titleist 910 adaptors, you'll either have to go online (eBay or GolfWrx ) or remove the adaptors from the stock shafts and install them onto the new ones. I've done over 50 910 SureFits and it's a very easy job. For warranty and quality control purposes, Titleist will not sell the adaptors individually nor will they install the adaptors onto shafts you send in. Having done repairs and warranty work for 15 years, I believe that to be a practical policy on their part.
