In the G400 SFT (Straight Flight) fairways, weight closer to the heel, a lighter swing weight and higher lofts help square the face, promote right-to-left shot bend (right-handed golfers) and launch the ball higher. Faster ball speed and stopping power come from an innovative maraging steel face. One of the strongest alloys in the world, maraging steel is commonly used in the aerospace industry, where strength and flexibility are necessities.
Maraging steel face saves weight, is thinner, and flexes more. Weight saving raises MOI and Maraging face increases ball speed. SFTec(Straight Flight Tec) assists in fade correction by moving weight towards heel
