Srixon ZX4 MKII Irons Features

Progressive Groove System

With the longest irons, Srixon gave each progressive iron a different groove channel to create the distance and accuracy golfers want in game-improvement irons. For the irons used inside 150 yards, the grooves are deeper and closer to slice through grass and other impediments to provide clean contact.

Tour V.T. Sole

The V.T. Sole offers higher bounce to help golfers maintain the face angle into the golf ball, even if they are using a steep attack angle. What’s also great about the unique sole design is that the club maintains swing speed even if you strike behind the ball.

MainFrame Milling System

The MainFrame utilizes a variable thickness pattern along the channels, grooves, and cavities carefully milled into the back of the clubhead of the Srixon ZX4 MK II set. These new clubs also offer a lower CG with the MainFrame, helping golfers find consistent iron play wherever their ball lands on the course.

Srixon ZX4 MKII Irons In Depth Review


The Srixon ZX4 MK II iron set offers a clean, uncluttered appearance. The classy look of the iron set will make you think you are playing with a high-quality forged collection. Even at address, the thicker topline doesn’t distract or make you feel that you’re playing with a lesser set.


At impact, the Srixon ZX4 iron set delivers crisp feel and immediate responsiveness to help you adjust your game as you play. I really adored how each iron responded to shots off the toe as the vibration was held to a minimum.


For a game-improvement iron, the Srixon ZX4 MK II delivers clean, professional-grade sound that boosts confidence. The iron delivers solid overall sound that does not distract and actually gives the appearance that you are playing with a forged iron set and not game-improvement irons.


The Srixon set provides a fun, engaging experience on the links with boosted distance and a repeatable shot shape you can depend upon, regardless of your lie.

The shorter irons are delightful, providing quick and easy launch with length to burn. The long irons are dynamic, providing the distance you’d expect from longer clubs and the smooth launch you’d find normally in a fairway wood.

One of the biggest points of interest for me is the stronger lofts present on the set. Even by modern standards, Srixon’s decision to strengthen the loft degree as the set progresses helps increase shot height for golfers that hit the ball low.

Compared to the ZX5 MK II irons, a players’ distance iron, the Srixon ZX4 MK II offers the forgiveness and launch of a super game-improvement iron.

What do other golfers think?

Golf Digest awarded the Srixon ZX MK II irons a spot on their 2023 Hot List, giving the iron set their prestigious Gold medal.

For a game-improvement set, the ZX4 MK II irons exceeded expectations. Delivering jaw-dropping clubhead speed, these irons are all about distance and accuracy.

Ideal for high and mid handicap golfers, the Srixon set carries a stellar reputation and on the course it certainly backs it up by producing high, straight shots with a steep landing angle that stops shots cold on the green with the short irons.

When it comes to golf irons, Srixon has long been one of the best manufacturers, and their impressive ZX4 MK II irons offer more distance and better dispersion than the prior version, making this a set worth your time.
