Unfortunately Titleist is not a retailer and does not sell shafts. Team Titleist is a forum for Titleist loyalists who share ideas, information and fellowship. Welcome to our site. One suggestion is to go online. They are available thru various sources at different prices. Me, I would first check with a local Titleist account repair shop and have it done professionally. They might have one in stock. Have you checked there?

Sorry to hear about your 6 iron. There are many, many golf shops that do replacement shafts and yours is a common one so they should have no problem matching it. Find a shop near you and in the future, try just throwing your driver head cover. I find them to be much more durable. Cheers.

Your best bet is to look on eBay or order a new one from GolfWorks, or Amazon if they have it. A 6i shaft should typically measure at 37.5” playing length.

One other possibility is buying a used 6i with the same shaft on eBay or wherever, disassembling and using that shaft. It’s possible that’s cheaper , but for reference a brand new shaft will be about $30
