Srixon ZX Mk II Custom Utility Iron

A tour-proven long Iron alternative, featuring control and elevated launch in a forged, hollow design.

ZX Mk II Utility Irons

ZX Mk II Utility replacement long Irons offer every player—even tour pros—more long-game power, control, and forgiveness in a blade-like design with a hollow build. Their low Centers of Gravity and long-Iron forgiveness easily elevate your launch. Featuring a narrow topline, our widest soles, and minimal offset.


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 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 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.


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.
