Short Description BUILT FOR SPEED Qi4D Max Lite is our first modern non-titanium driver. The 7075 aluminum collar is forged and machined to provide you ample adjustability in an ultra-forgiving head without compromising speed. If you’re looking for increased clubhead speed, the ultralight spec package includes the family’s lightest head, shaft and grip. The redesigned, modern address shape provides the perfect blend of speed and forgiveness and inspires confidence in the address position.
