Ping G440 K Driver Designed for golfers who want maximum speed and forgiveness from the tee, the G440 K Driver represents PING's most stable adjustable driver to date. With a focus on extreme MOI, ball speed retention, and customisable shot shaping, the G440 K is built to keep the ball in play more often while still delivering powerful, consistent distance. EXTREME FORGIVENESS WITH ADJUSTABLE CONTROL At the core of the G440 K is a new 32-gram adjustable back weight, allowing golfers to fine-tune their ball flight by positioning the weight in Neutral, Draw, or Fade settings. This flexibility helps players dial in their preferred shot shape while maintaining exceptional stability through impact. This design helps the G440 K achieve PING's straightest and highest-MOI adjustable driver to date, delivering impressive forgiveness and consistent ball speed across the entire face. LOWER, DEEPER CG FOR MORE BALL SPEED The G440 K's back weight is 4 grams heavier than the fixed back weight used in the G430 MAX 10K, PING's previous highest-MOI driver. By positioning more mass around the perimeter of the head, MOI is increased while the centre of gravity is pushed lower and deeper. This CG placement works in harmony with the faster T9S+ face, helping golfers generate higher ball speeds and more consistent launch conditions, particularly on off-centre strikes. WEIGHT SAVINGS THROUGH ADVANCED MATERIALS To maximise forgiveness without increasing overall head weight, PING engineers focused on redistributing mass using advanced construction techniques. The Dual Carbonfly Wrap crown and sole, combined with Free-Hosel Technology, remove weight from key areas of the head. DUAL CARBONFLY WRAP & FREE-HOSEL TECHNOLOGY Weight savings are achieved from multiple areas: 3.5g saved from the sole 1.5g saved from the crown 3g saved from the hosel and heel section This freed-up mass is repositioned around the perimeter of the driver head - including the back weight - further increasing MOI and placing the CG lower and deeper. The Free-Hosel design also increases face flex in the heel area, helping retain ball speed on strikes hit away from the centre. IMPROVED SOUND AND FEEL Forgiveness and speed are paired with refined acoustics thanks to a composite crown bridge and integrated acoustic sole ribs. These ribs connect the crown and sole to help control vibrations at impact. The result is a more muted, solid sound and a powerful feel through the strike, giving golfers clear feedback without harshness. FACE AND BODY CONSTRUCTION The G440 K features a cast Ti 811 body combined with PING's T9S+ face, engineered to deliver faster ball speeds across a larger hitting area. With the largest front-to-back profile in the range, the G440 K inspires confidence at address while maximising stability through the swing.

The PING G440 K Driver is ideal for golfers who want maximum forgiveness with the added benefit of adjustability. It suits a wide range of handicaps, particularly players who prioritise stability, consistent ball speed, and keeping tee shots in play while still being able to fine-tune shot shape. What makes the G440 K Driver different from other PING drivers? The G440 K is PING's highest-MOI adjustable driver, featuring a 32-gram adjustable back weight that can be set to Neutral, Draw, or Fade. This allows golfers to dial in their preferred shot shape while maintaining extreme forgiveness, stable flight, and excellent ball speed retention across the face. How does the adjustable back weight benefit performance? The heavier back weight positions more mass around the perimeter of the clubhead, increasing MOI and moving the centre of gravity lower and deeper. This helps improve launch conditions, preserve ball speed on off-centre strikes, and produce a more consistent, straighter ball flight. Is the G440 K Driver adjustable for loft and lie? Yes. The G440 K Driver features PING's adjustable hosel, allowing golfers to adjust loft by ±1.5 degrees. This enables fine-tuning of launch, spin, and trajectory to suit individual swing characteristics and course conditions.
