Pretty sure the answer is nope. You might try and ask your local pro, if they are approved Titleist distributors. Impossible for Titleist to comfortably have a warranty on their products unless they do the complete assembly. Just recently started allowing shipments with the grip uninstalled and in the box as many customers didn't want to wait for a specific grip and thought they could find what they needed on their own.

Dale - The grip issue is not always simply because of a wait. For me the issue was more that I prefer a Jumbo grip on my clubs which is not an available option . I hate the thought of cutting off a brand new unused grip just to install my Golf Pride CP2 Jumbo as soon as the club arrives. Having the grip shipped "in box" allows me to donate the grip to a friend :)
