In November, Srixon officially lifted the veil off their new ZX5 and ZX7 irons, and the feedback has been overwhelmingly positive. ZX5 hits the mark as a player’s distance iron, while ZX7 offers a compact shape that undoubtedly focuses on the stronger iron player. Those target demographics should come as no surprise for anyone familiar with their lineup in the past. However, it’s been since the Z 355(2015) irons that Srixon manufactured a set that offered more forgiveness for the golfer who needs it. That void ends today as Srixon introduces the world to the ZX4 irons.
ZX4 joins in on the hollow body revolution while incorporating some of the technologies we have come to expect from Srixon. Similar to the ZX5, these irons feature Srixon’s new MainFrame design. MainFrame is a variable thickness face design that maximizes the ball speed across the face. As is part of the rage these days, this face pattern was engineered with assistance from artificial intelligence and machine learning-based off of thousands of simulations. Combine this face design with the hollow body construction, and the ZX4 irons a built for forgiveness and speed.
According to Dustin Brekke, Director of Engineering at Srixon, “The new Srixon ZX4 irons mark a new revolution in forgiveness for Srixon. The irons include a fully hollow construction with wide soles for getting the center of gravity extremely low and providing maximum forgiveness from the turf.”
Over the years, many players have come to enjoy the feeling they get from a Srixon iron, which presents a challenge on how you make a hollow set from short to long irons keep up with that reputable feel? The answer to that comes from the marriage of the forged HT1770 Steel face and the 431 Steel body. While the lightweight and strong face allow for more flexing at impact, the body works to absorb many of those vibrations, which will help create a softer feel in the hands.
Another part of that signature feel players have enjoyed from Srixon’s offerings isn’t just because of how the ball feels/sounds coming off the face, but instead how the club reacts to the ground. With various V.T. sole designs through the years, Srixon has been one of the leaders in creating improved turf interaction. Thankfully, the Tour V.T. sole is indeed present here, which means these ZX4 irons should cut through the turf with no issues, even for those of us who tend to hit just a bit behind the ball.
Now for what everyone loves to look at, the specs. As you might imagine, a clubhead designed for forgiveness, speed, and high launch is going to have some stronger lofts. As you can see on the chart below, ZX4 does indeed have some aggressive lofts. For comparison, the 7-iron in the ZX4 is 28.5°, 2.5°stronger than the 31° ZX5 7-iron. Srixon has used tungsten in the long and mid irons to ensure that even with these strong lofts, the ball will launch consistently high. Offering even more help in the launch department is the Nippon N.S. Pro 950 GH Neo steel shaft. Those looking for graphite will find the UST Mamiya Recoil 760/780 SmacWrap is the stock offering.
Srixon’s most forgiving iron is here! The ZX iron lineup clearly offers something for everyone, whether you are a well-accomplished ball-striker, a player who wants a distance package with a more players style look, or someone who needs the extra help in distance and forgiveness. What do you think? Could you find the ZX4 making its way into your bag this season?

Their initial launch is quite high still even at that loft.
I believe as people test them out, it will make more sense.
We will discuss that during the THP Live today.
I know @Jman @JDax and a few others have tested these out and can offer feedback on the sound. After the Cleveland UHX, which is one of the better sounding hollow body long irons, I can safely say that to me, they nailed the sound.
Absolutely got the sound right. And, they’re silly long. I mean silly long.
Sure, it’s not a tiny tiny profile, but they look tremendous, feel fantastic, launch easy, and go forever.
It’s pretty mind bending how easy they launch though, the lofts are strong yes, but the ball gets up so much easier than the loft.
One of the things I like about my srixon irons is the stronger lofts in 5/6 irons and the need for one less club from 23 – 58 degrees.
As far as bending to 25, my thought is to bend the 6i the 0.5 stronger versus bending the 5i. The least amount of bending will have the least impact on bounce.
Thanks for the responses guys! I was wondering if some of the lessons they learned from the UHX carried over into this design. Glad they got the sound right on this one.
Hey @Jman I know you love the new ZX utility, but would you put a new ZX4 4i or the Utility in your bag as a driving iron off the tee for tight par 4’s?
Sadly I forgot to hit the long iron. I do think these will take some of the spotlight from the ZX’s though, they’re super hot.
Remember on the THP Showcase with Srixon when they were asked, “Why does the new ZU only go to 4 iron, when the U85 was offered all the way to 6 iron?”
They said they couldn’t really discuss it right now, the ZX4 is the answer, they didn’t need to because it’s a whole set of UT irons.
They are probably the most fun to hit out of all of the irons in the tech studio.
I have a UHX with a recoil that I won courtesy of UST and Cleveland on Instagram, and while the sound is high pitched it does still feel really solid. Glad to hear these also sound good.
The UHX was a super under-the-radar good iron, and I wonder if them doing something in the Srixon brand will get more people interested.
Shafts they put in are top notch!
Curious how tidy they look at address.
Srixon event this year is going to be ?
I genuinely think it is the way light hits the backside of the texture in photos. In hand they look pretty darn good. Perhaps during our live stream today, video does a better job of it

how beefy? Because a lot of the info I had talked about how it was more of a midsize package, which had me excited(still am). I’m actually curious how they look side by side to the T400’s.

Thanks for the pic. Looks better here. Kinda plain but classy at the same time.
awesome notes on this! Eye for detail. I’d be curious why UT and not ZX4, ZX5, ZX7 combo? Similar to Another brand with an ultra forgiving offering
About an inch wide sole would you say ? I’ve been measuring a lot of GI and SGI irons lately and most hit that 1” wide sole mark.
Looks like 23.7mm or .933 inches on the 4i and a tad more on the PW:

Neat I didn’t know they published their specs like that. Wish more companies did.
I had been looking for new irons, waited for a few releases and decided on a set and I am super happy with what I went with. On the flip side of that, I was looking for a hollow body, something that may be a little more playable. I talked about the B21 for awhile a know somethings didn’t check the boxes with them but.. I know the HMB’s had some things that also didn’t check the boxes also. These are all different irons I know. I have been a srixon fan, really like their irons, love the v sole. I guess what burns is I would’ve like to have looked at these. I guess long story short, if what I’m getting doesn’t work out for some reason I’ll take a hard look at these and see what happens, I’m just not financially setup or wife approved to have 2 sets of irons to play. This release just has me honestly second guessing more than any other iron situation I’ve been in..
Isn’t this basically the iron the srixon is replacing? Honest question, is the main thing that they think they have a quality item and it will be better received as a Srixon product than a cleveland product? Can’t argue with them as the Cleveland name only seems to really resonate with the consumers as a wedge, but maybe I am wrong.
Genuinely I don’t believe so. I think Cleveland is still alive and well. In my opinion it is a Srixon growth area. A hole in the lineup so to speak that is no longer vacant. Similar to what DCB did for Apex and that line, ZX4 combines the golfer that wants a premium iron with a forgiveness level that wasn’t previously available. I would expect the Cleveland lineup to be updated at some point based on previous release timing and while I have no information as of yet, do not think they would abandon the UHX class completely or they will remain in line, similar to CBX at the last release. Two different constructions and two different price points.
Hope that helps.
Good info there, thanks. Looks like they might have a very attractive topline, only 1mm wider that the 5 or 7, of course topline appearance also depends on how they shape it. And the sole width doesn’t look that bad either, which in the long irons was a problem for me in the UHX. When I hit the UHX I loved the looks of the PW and 7-iron, but then hit the 4-iron and it was just hard to look down at.
This is exactly who I was thinking of this morning, Callaway released 3 irons while srixon released 2 and I though where’s the 3rd. Even a couple months ago there were hints about this zx4 but to me being naive I didn’t continue wondering. And here it is.. While I understand not every OEM releases more than 1 or 2 or 3 irons or whatever I still thought something may be missing.
Yeah, or like the Mizuno Hot Metal/Hot Metal Pro in the JPX line up, just fitting a more high end GI set to expand the line.
Yeah, or like Mizuno and their Hot Metal/Hot Metal Pro in the JPX line. Just filling out the line up by adding a high end GI set to the line.
Makes perfect sense and glad that Cleveland is going strong. Have always enjoyed that brand and only more so after my time with them in the desert.
As a high-handicapper, I’ve been giving Callaway’s Apex 21 DCB a close look. But I actually hit my current very-old-tech CB irons pretty well, from the 6i on up, so it may be a blended set, such as Callaway’s "Sweet Spot" will work for me. Wondering: Any word on whether Srixon will do something similar with the ZX series? E.g.: ZX4 3i-5i, ZX5 6i-AW?
Man that was a fun weekend with Jamie Sadlowski.
I was just telling people about playing with him and how a) far he hits it, but b) how he was so freaking cool. Wonder how many cars he dented at top golf….
