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.
- The stock graphite option is the UST Recoil 760/780.
The Srixon ZX4 will be available for pre-order starting February 22 and will be on retail shelves on March 5.

Since our founding in 2005, the bedrock of GolfWRX.com has been the community of passionate and knowledgeable golfers in our forums, and we put endless trust in the opinions of our GolfWRX members — the most knowledgeable community of golfers on the internet. No other group of golfers in the world tests golf clubs as frequently or as extensively, nor is armed with such in-depth information about the latest technology.
Below are the results of GolfWRX member voting for the 2025 best driver, along with the vote percentage for each club.
Best driver of 2025: The top 5
5. Callaway Elyte Triple Diamond: 6.02%
Callaway’s pitch: “For golfers looking for a fast, forgiving, yet workable driver, the Elyte Triple Diamond features a tour-inspired shape and is the preferred model by most Callaway tour players.”
You can read what other golfers are saying about the driver in the GolfWRX forums, and see our launch piece here. Shop the Callaway Elyte Triple Diamond here.
4. Ping G440 Max: 6.86%
Ping’s pitch: “The most forgiving G440 model, MAX has a hotter face to generate speed and distance, and a lighter overall system weight with a longer shaft (46″) for faster clubhead speed, higher launch and longer carries. The Free Hosel and Carbonfly Wrap crown save weight to create our lowest CG ever and increase forgiveness while contributing to a more muted, pleasing sound.”

3. Ping G440 LST: 9.53%
Ping’s pitch: “LST is an especially good fit for faster swings, offering less spin and more control with a penetrating trajectory. A hotter face, lighter overall system weight and longer shaft (46″) deliver more speed and distance while maintaining tight dispersion.”
@phizzy30: “Not a fan of Ping drivers in general, but 440 LST takes the cake. It’s super forgiving across the face for a low spin head, looks and sounds good and the ability to make it play neutral or slightly fade biased through the hosel settings is very appealing.”

2. Titleist GT3: 16.55%
Titleist’s pitch: “The GT3 Driver offers Titleist’s boldest combination of power and personalization through adjustable performance. Dial in the CG Track to your frequent contact location to make your biggest drives even bigger while taking total control over flight and shaping.”
@mrmikeac: “I’ve been Anti-Titleist for years and years and years (outside of Vokey, of course). With that being said, HOLY BEGEEZUS the GT3 driver is an absolute NUCLEAR MONSTER! This thing blew my G430 10K Max out of the water in every single category. Forgiveness is the biggest thing that stands out of me, the 3 model has always been one of the less forgiving models in the past but this GT3 can take bad shot after bad shot and still end up in the fairway, I think a ton of that has to do with the adjustability, it’s actually effective. Feel and sound is perfect, that solid crack is so addicting to hear and when you hit it out the screws this thing can absolutely bomb it. Titleist, I’m sorry for doubting you. You have converted me.”

1. Titleist GT2: 22.91%
Titleist’s pitch: “Delivering impressive distance from any impact point, the Titleist GT2 Driver extracts maximum performance through a forgiving design. Get the stability and added confidence of a high-MOI driver without sacrificing speed.”
@DTorres: “The Titleist GT2 has proven to be the best driver of the year. Packaged in a classic profile, GT2 perfectly balances performance and forgiveness while consistently being a high performer across all categories.”

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.

2* of difference at the top of the bag, but 6* at the bottom… Come on…

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.
