25 drivers in one! The Genesis Titanium Drivers allow for complete customization for both swingweight and directional control. Each driver will come installed with a 10g tungsten screw in the heel, 6.5g stainless screw in the center and a 3.5g stainless screw in the toe. These screws are completely interchangeable. The club will come with a kit containing 2 more of each weight screw, matching 4mm Allen wrench and directions. This allows you to customize the weight from 196g all the way to 216g in order to achieve the proper swingweight at multiple length and shaft weight options and to fine-tune for draw or fade bias.
