Golf tinkerers and club builders, this one's for you! This new .370\ hybrid adapter sleeve lets you swap shafts on your Titleist hybrids with ease. It's compatible with a bunch of models: the newer GT and TSR series, the TSi, TS3, TS2, and even the older 818 hybrids. Works for both right-handed and left-handed clubs, which is super handy. The brand is The Golf Club Trader, and it's brand new in its original packaging. No MPN or UPC, but it's a straightforward adapter that does the job. If you're looking to experiment with different shafts, adjust loft/lie settings (if your clubhead allows), or just repair a broken adapter, this sleeve is your go-to. Installation requires some specialized tools – like a torque wrench and maybe epoxy – so it's best if you have some club building experience. But once it's on, you can pop your hybrid head on and off different shafts in seconds. Perfect for golfers who love to customize their gear, repair shops, or anyone with a Titleist hybrid that needs a fresh adapter. Get the right fit and performance by building it yourself!
