The 913D2 driver features a 460cc full-pear shaped head designed for maximum forgiveness and a slight draw bias. Its 6-4 Titanium face insert has a thick central portion that mirrors the outer face profile, but tapers down to match up with the body thickness at the face perimeter. This new insert increases ball speed by up to 11 percent from Titleist's 910 drivers. Want to play Johnson's clubs?
