Make sure this fitsby entering your model number. Epic Speed Fairway Woods are engineered to set a new bar for ball speed technologies. Epic ball speeds start with our new Jailbreak A.I. Velocity Blades. Callaway engineers used A.I. to design a completely new Jailbreak system which spreads and angles the Jailbreak blades. Every model and every face in our fairway woods are uniquely designed using advanced A.I. It’s a proven ball speed design that puts an even greater emphasis on center and off-center ball speeds. The A.I. face is forged using a high strength C300 Maraging Steel for speed and spin consistency across the face. The forward Center of Gravity (CG) is combined with a new leading-edge to promote a strong ball flight, outstanding spin robustness and consistent shot shape dispersion.
