G440 K A record-setting MOI for a PING driver makes the G440 K our straightest and most forgiving model while delivering faster ball speeds and CG-shifting adjustability for more distance. A lower and deeper CG position is achieved through weight savings from its carbon crown and sole, delivering ball-speed gains and the record-setting MOI that leads to longer and straighter results. Dual Carbonfly Wrap The dual wrap and Free-Hosel Technology save weight from the sole, crown and hosel region, positioning the CG lower and deeper for added ball speed and forgiveness. CG Shifter A heavier high-density tungsten back weight adjusts to one of three positions (Neutral, Draw, Fade), shifting the CG to optimize ball speed, launch and spin for straighter and longer results. Fast & Forgiving Face The forged T9S+ face is thinner with a dual-roll radius to optimize spin and increase ball speed across the face for greater distance. Advanced Aerodynamics The confidence-inspiring shape is our largest profile front to back to maximize forgiveness. Crown turbulators improve aerodynamics for more speed. Sound Design A composite crown bridge and sole ribs attached to the crown and sole improve sound with a more muted and solid impact experience.
