Why would they make them available for individual sale?  Send it back to Titleist and have the tip installed correctly for a minimal charge.  That way you know what you are getting and should have a warranty for it.

Kevin, If Titleist's intention were to make extra money, they would have SureFit adaptors for sale. Instead, the company is concerned about delivering authentic and quality products and workmanship which always benefits their customers in the long run. So, Titleist buyers and the company ultimately win. Anyone who is frustrated by the adaptors not being sold without control has to step back from their individual situation and look at Titleist's. Over the last 15 years in the industry, I've seen virtually everything that people tinkering or selling golf clubs can produce. Simply stated, there are enough unethical sellers and poor clubmakers that Titleist has to protect the brand because that is what counts. Poor quality, craftsmanship, and counterfeits ultimately reflect on the company. That being said, I'm on a budget like many people. I have a high end shaft in my driver and took the steps to make sure the tip was done properly. I understand if the shaft fails, it's on me. I'm not worried about the 913 head, because I've seen fewer problems with Titleist metalwoods than any other company. It's actually not even close.
