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?

I liked the 355’s a lot – the tech in this new lineup is impressive. I hope people try these out. The 355 irons were a great "bang for the buck" choice – I expect these will be too.
I’m with you on the looks part. I love how the ZX5 irons look, but I could see using at least a 5 iron in the ZX4. And I’d be curious to see if the ZX4 4-iron would be easier to hit consistently than a hybrid (I typically struggle with hybrids)

The way I measure I had the RAD and ZX4 about dead even on head measurements. Very comparable size wise for sure.

You are right, they are very similar in overall size. I didn’t have a ruler and won’t dispute your numbers… my impressions on sole width mostly based on visual cues and first looks.
I concur with this, I have hit them in the Tech Studio and they are longer than even the Apex DCBs & probably the longest iron in the Tech Studio at the moment…
They aren’t a full club longer than the Apex DCBs , but they are longer.
This is the reason that the new Srixon Utilities only go to 4 iron & not the 6 iron like the U85s.
The heads are heavy.
Think their is set a of golfers that this club will help for sure.
I’m in the same boat. Hoping it shows up before I leave for Branson but I don’t expect it to
You will need it if the wind keeps up. I hope my 5i is on its way.
I’m thinking about a ZX4 to put in the 5-iron spot my ZX5 set. The 5-iron is the line of demarcation in my bag. I love my 22* hybrid. I love my 6-iron. But I just don’t have the same confidence with the 5-iron. My only concern is the reports of how hot it is. The ZX5 5-iron is 24*. The ZX4 5-iron is 23*. My hybrid is 22* albeit with a longer shaft than what the ZX4 5 iron would play with.
Would it play an ‘in-between yardage’ or closer to the hybrid.
Did you get a chance to test your 6 iron out in Branson?
Saying all that there are a few positives to talk about. First this thing gets the ball in the air. If you struggle with height look at these irons. I was hitting this 6i as high as my G425 PW.
Second, it’s pretty damn forgiving. Even on the heel shots I was probably getting 80-90% of my expected distance the ball just went higher and right.
Third, don’t worry about the ball stopping on the green. It goes so high that is not an issue. I had one shot in particular that stands out. I was 175-180 out and the shot was uphill and had to carry a bunker and stop quick. It did both easy
From what I saw it gaps pretty well between my 7w and 7i. I need more time with it to see if I need to look into a heavier shaft to stop the fat shots but so far it looks like a keeper
Yep, just posted what I saw from it
I think most actual driving irons are one trick ponies and end up even if you use them off of 4 or 5 tees a round, become a loss leader in your bag.
What I mean is driving irons typically cost more than a regular SGI or GI iron. In some cases quite a bit more. For how little you use it and the cost, it can become a loss leader. While SGI and GI irons are much cheaper and I think have more all around game ability. They are much easier to hit off the turf than a driving iron.
I used a Titleist t400 iron in this fashion last season.
The distance is going to be golfer specific. If you are a high spin player then the ZX4 5 iron will be closer to your hybrid in total distance. It removes a bit more spin the the ZX5 does shot for shot for most people and the higher launch will carry it farther. However the extra handle length on your hybrid and the fact that they already are lower spin then most iron counterparts means it should go farther when both are hit on the Sweet spot.
Good information, still waiting on my 5 iron. Hoping it magically appears on my doorstep soon.
I’ve only got a 6i in the ZX4 so I can’t speak for the short irons. From what I’ve seen next to my G425’s the ZX4 are way more forgiving
True this. I hit a 5 iron yesterday 176 which I haven’t done in years. Loving these irons.
Wow music to my ears. I was considering the 425s over the ZX4s
Now narrowed down to the ZX4 and the Ping 710s
I’ll be curious on this one. All the reviews I’ve come across show lower than anticipated launch.
in my testing they hit what I normally see from stronger lofted irons.
That is pretty shocking I guess, but I don’t see too many others. We have had a lot of people hit these and have not seen lower launch and I hope people are not reviewing and "assuming" based on loft.
I’m excited to see this.
How’s the spin on them ? Are they achieving the distance with high launch and low spin ?
Full video coming soon with tons of data and a breakdown.
Great stuff. REALLY fun to hit.
Very strong chance that I’ll be adding a ZX4 4-iron to my ZX arsenal.
EDGE EX has more offset, but less loft. I will try to get some blade measurements for you.
The Srixon’s are a good bit stronger in the mid irons and a little less in the short irons
Yeah, I should have said EDGE EX has more offset and are weaker lofted.
