The G440 LST Driver is optimized to deliver more ball speed through multiple advancements, including PING's deepest CG in a driver to date and a shallower, thinner face, while continuing to ensure the game-changing forgiveness expected from a PING driver. The overall system weight is lighter by 10 grams and the standard shaft length is A 1/4" longer than previous models to help golfers swing faster for higher-launching, longer drives with a pleasing, slightly muted sound.The G440 LST (Low Spin) design appeals to players with faster swing speeds, providing lower spin and more control in 9deg and 10.5deg lofts with the three-position back weight.Trajectory Tuning 2.0
