Each Srixon ZX MK II Utility Iron Head purchase will come assembled with a KBS Tour Hybrid Graphite Prototype (.370) Shaft and a grip of your choice from the dropdown menus that are provided. Our club builder will call you to confirm the specs after the order is placed.  

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.

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.
