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 minimal offset and narrow top lines.
MAINFRAME MainFrame is a variable thickness pattern of grooves, channels, and cavities carefully milled into the backside of the Iron face that maximizes flex at impact.
UTILITY IRON SHAPES Our widest soles, combined with minimal offset and an appealing look at address, makes our forgiving, hollow, ZX Mk II Utility long Irons professional favorites.
FORGED MULTI-PIECE CONSTRUCTION ZX 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.
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 club head speed through turf and improve shot versatility without sacrificing forgiveness.
