2021 Srixon ZX4 irons: The final piece of the ZX puzzle
When it comes to building the perfect set of irons, there are endless options, and to help golfers get the most from their iron games, Srixon is completing its ZX iron series with the introduction of the all-new hollow-body ZX4 for 2021.
Considering the recent success of the already popular ZX7 and ZX5 irons, which were released a few short months ago, and the growing popularity of Srixon irons on tour and with consumers, the addition of a fast hollow-body iron makes a lot of sense, given Srixon’s ability to create fast, forgiving, and beautiful looking clubs packed with technology.
“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.
The ZX4 irons accomplish this in addition to Mainframe technology, Tour V.T.Soles, tungsten weighting, and the look and feel expected with Srixon ZX irons.”
-Dustin Brekke, Director of Engineering at Srixon.

2021 Srixon ZX4 irons: Technology
The ZX4 irons share the same face technology as the ZX5 and ZX Utility known as “MainFrame.” This MainFrame face creates a unique thickness optimization for each iron in the set based on tested strike patterns and was refined using machine learning AKA AI. These varying thickness patterns are all individually milled into the rear of each face (made up of grooves and cavities) to expand the COR.
The face itself is made from forged HT1770 maraging steel and attached to a 431 steel body for great ball speeds and soft feel. Inside of the 431 stainless steel body of ZX4 mid and long irons is high-density tungsten in the sole to lower the center of gravity, boost forgiveness, and help promote high-launching shots.

The other key design feature that sets the ZX4 apart from other irons in the hollow-body category is Srixon’s Tour VT sole to improve the performance through the turf compared to an iron of similar sole width.
Over the years, the VT Sole has gone through some changes, which resulted in softer lines and smoother edges.
In the new ZX series, Srixon returns to its roots with a move aggressively angular VT sole, including well-defined heel and toe notches for improved turf interaction.

Just because the ZX4’s are designed to be game improvement doesn’t mean they can’t offer “players iron-like control.” They achieve this with progressive grooves through the set. The 8-iron through pitching wedge have sharper, narrower, and deeper grooves to channel moisture and debris away more efficiently to generate more spin and shot-stopping control on approach shots.
When compared to the rest of the new Srixon iron series—which includes the ZX7 and ZX5—the ZX4 fits nicely between the ZX5 and utility and offers an extremely clean look from address. Not only that, but the blade lengths have all been configured so golfers that plan to use the ZX4 to build combo sets will see a smooth transition from one iron to the next and even into the new utility.
Price, specs, and availability
The ZX4 irons will retail for $1,299.99 (for an 8 piece set) in steel and $1,399.99 (for an 8 piece set) in graphite.
- The stock steel shaft is the Nippon NS Pro 950GH Neo.

Editor’s note: This is an excerpt from a piece our Andrew Tursky originally wrote for PGATour.com’s Equipment Report. Head over there for the full article.
The timing of Lowry’s putter changeup was curious: Was he just using a Spider putter because he was paired with McIlroy, who’s been using a Spider Tour X head throughout 2024? Was Lowry just being festive because it’s the Zurich Classic, and he wanted to match his teammate? Did McIlroy let Lowry try his putter, and he liked it so much he actually switched into it?
Well, as it turns out, McIlroy’s only influence was inspiring Lowry to make more putts.
When asked if McIlroy had an influence on the putter switch, Lowry had this to say: “No, it’s actually a different putter than what he uses. Maybe there was more pressure there because I needed to hole some more putts if we wanted to win,” he said with a laugh.
To Lowry’s point, McIlroy plays the Tour X model, whereas Lowry switched into the Tour Z model, which has a sleeker shape in comparison, and the two sole weights of the club are more towards the face.
Lowry’s Spider Tour Z has a white True Path Alignment channel on the crown of his putter, which is reminiscent of Lowry’s former 2-ball designs, thus helping to provide a comfort factor despite the departure from his norm. Instead of a double-bend hosel, which Lowry used in his 2-ball putters, his new Spider Tour Z is designed with a short slant neck.
“I’ve been struggling on the greens, and I just needed something with a fresh look,” Lowry told GolfWRX.com on Wednesday at the 2024 Wells Fargo Championship. “It has a different neck on it, as well, so it moves a bit differently, but it’s similar. It has a white line on the back of it [like my 2-ball], and it’s a mallet style. So it’s not too drastic of a change.
“I just picked it up on the putting green and I liked the look of it, so I was like, ‘Let’s give it a go.’”

Come on doubters — there’s a reason for variable gaps. Engineers with months of testing to come up with a complete set have 10,000% more cred than the unseeing and unbelieving.

i’m turned off by the lofts. first thing i do is look at the pw. if its anything less than 45 the irons are out in my book.

These are cool but 2-degree and 2.5-degree gaps in the long irons is practically useless for most people. Especially amateurs, they probably need at least 3.5-4 degree gaps in the long irons. Even lots of pros have 3-4-degree gaps in the long irons.

lol what is “player’s iron like control” on a 28* 7-iron? I’d be trying to control that thing on its way to the Moon.

Next year these irons will have MCT or Moon Control Technology.
