FAST AND PURE
New ZX Mk II Irons are a culmination of fast and pure. A pure feeling at impact, for purer strikes, and a pure sound. With tech-driven ball speed in every number, energizing every shot.
ZXiU Utility Irons
FEEL. DISTANCE. CONTROL.
ZXiU Utility Irons are potent long Iron replacements—even among tour pros—with elevated power, control, and forgiveness in a blade-like design with minimal offset.
MAINFRAME
MainFrame is a variable thickness pattern of grooves, channels, and cavities carefully milled into the backside of ZX4 Mk II, ZX5 Mk II, and ZX Mk II Utility Iron faces that maximizes flex at impact. MainFrame not only boosts COR, it also repositions mass away from the face and into the toe and sole for a lower Center of Gravity. This creates more than just faster ball speed, but also more consistency and forgiveness, enhancing all aspects of your Iron play, shot for shot.
SOLE NOTCHES
Sole notches on the heel and toe sides lessen drag by reducing the amount of surface area that contacts the ground. Ultimately, they provide better clubhead speed through turf and improve shot versatility without sacrificing forgiveness.
FORGED MULTI-PIECE CONSTRUCTION
ZX Mk II Utility’s forged SUP10 faces are strong yet light—increasing face-flex at impact for enhanced speed and distance—while a forged 1020 Carbon Steel body absorbs vibrations for a softer feel.

COMPARE IRON SHAPE
SHAPE CHANGES FOR ZX MK II IRONS VERSUS LAST GENERATION:
- All toplines are now the same thickness
- ZX4 has thinner soles and longer blade lengths
- ZX5 has thinner soles
- ZX Utility has wider soles
Tour-level and low-handicap players prefer the thin topline, narrow sole, short blade, and minimal offset.
A wider sole with moderate blade length and offset provide both distance and forgiveness.
Moderate sole width, longest blade length, and highest offset. Our strongest lofts promote a piercing launch with enhanced distance and rollout.
Our widest soles, combined with minimal offset, make these forgiving long Irons professional favorites.
