.335 Billy Bob’s Universal Fluted Adaptor Ferrule for the Callaway VFT, ERC II and Great Big Bertha II, Steel Head III, Fusion and 454, FT 5, New FTi and Hyper X Drivers and Hybrids and the Big Bertha Diablo Driver, Octane Series Drivers.
These adaptors allow you to install .335 aftermarket shafts on the .350 heads.
I increased the diameter on the ferrule to cover the hosel; this is a tapered fit and not just any adaptor will work! We have incorporated Our Patented Perforated Sleeve Technology (U S PATENT # 6,887,163) that makes for better adhesion and a breeze to do. Also we use the same materials used on the original, which doesn’t change the feel of the club. This is very important, because this is a damping and protection system to the club, and it keeps the feel consistent. Beware of cheap plastic adaptors that can split during installation and they won’t give you the same feel when striking the ball.
Please Note* Make sure you use a 7/16 drill bit or .440 reamer to clean out the first step of the hosel, this will remove old epoxy, which will allow the ferrule to sit flush on top of the Club Head.
