Created with human intelligence yet perfected by the artificial kind, MainFrame is a one-of-a-kind face design that increases ball speed on every shot. While the engineers set the parameters, the computers ran the simulations—thousands of them—until Srixon had their fastest irons yet. Milled into the backside of each ZX Utility face, MainFrame is a variable thickness pattern made up of grooves, channels, and cavities. This pattern maximizes COR for more ball speed and incredible distance on every shot.

Srixon’s ZX Utility Irons deliver explosive speed into a compact address profile. Featuring new MainFrame technology and a hollow design, ZX Utility Irons provide all the speed and forgiveness you’ll need to go for the green in two or find that tight fairway.

Main Frame

A milled pattern on the backside of ZX Utility's face maximizes COR for more ball speed and more distance on every shot.

Hollow Design

Added forgiveness from fully hollow construction makes it easier to pure utility irons, adding distance, control, and a high launch off the tee or from the fairway.

Multi-piece Construction

Tungsten in the base of each ZX Utility lowers its center of gravity for a higher launch. A forged SUP10 face enhances speed and distance, while a forged 1020 Carbon Steel body absorbs vibrations for an extremely soft feel.

Crown Step

A stepped crown lower the center of gravity, optimizing launch and increasing MOI. The effect is more forgiveness and more consistency, shot to shot.
