Srixon Z Series irons have a reputation for combining distance and accuracy with signature feel. The new ZX irons continue that tradition with beautiful golf clubs that are equally powerful. They also feature a new automated intelligent design that helps fine-tune performance. The ZX4 irons complete the Srixon irons lineup that already includes the ZX5 and ZX7 models. ZX4 irons are made to be forgiving and soft with a hollow body. TGW put this design to the test in our exclusive video to bring you an in-depth review.

Technology
Srixon ZX4 irons feature a new technology it is calling MainFrame. MainFrame is a variable thickness pattern on the back of the club face using a series of grooves, channels, and cavities milled into it. The pattern used was chosen from a series of thousands of computer simulations until Srixon found the one that best-optimized speed all over the face. The result is maximum speed and powerful distance on every shot, no matter where you make contact.
The ZX4 irons feature a multi-piece, hollow-body construction. Srixon uses a stronger and lighter forged HT1770 steel face for increased face-flex when you hit the ball to increase speed and distance. The 431 steel body then absorbs unwanted vibrations for a softer feel. Finally, high-density tungsten in the base of the long and mid irons to lower the center of gravity for higher-launching performance. This all combines for a hollow iron that is the most forgiving in the ZX family. Golfers can strike the ball anywhere across the club face while still enjoying high, straight launch on shots that find their target.
Srixon included their signature Tour V.T. sole design in the ZX4 irons as well. This shape allows the club to get in and out of the turf easily for great feel and control. There are also notches in the heel and toe of the sole that allows players to work their shots without losing any forgiveness.
Finally, Srixon optimized the ZX4 irons through the set with progressive grooves. Consistency is key to make sure your distance and spin performance are where they need to be. The 3-iron through 7-iron has wider grooves that are ideal for the distance you need. The 8-iron through pitching wedge has deeper, narrower grooves that cut through grass and debris on approach shots for maximum spin where you need it.
Performance
To see how the Srixon ZX4 irons performed, we took them to our friend Rick Hatfield. Rick is the head golf pro at Flint Hills National Golf Club and TGW’s resident product expert. For this test, Rick used the 7-iron and swung it at an average speed of 83 mph. His average ball speed was 112.5 mph with a nice, high launch of 18.9° on average. Rick’s average spin rate was on the low side at 4,037 rpm which produced a shallower descent, allowing the ball to roll out a little more than other 7-irons might. Overall, Rick averaged 166 yards of carry distance with the ZX4 iron.
Who It’s For
Srixon ZX4 irons are the maximum distance model within the ZX family. They are designed to hit the ball high, far, and straight for the golfer looking for more help. These are game improvement irons through and through. Golfers who need some correction and need to maintain performance when they don’t hit the sweet spot will benefit most from the ZX4 technology.
Appearance
The Srixon ZX4 irons feature the largest head size and shape in the ZX golf club lineup. They have the widest sole, longest blade length, thickest topline, and most offset when compared to the ZX5 and ZX7 models. These golf clubs still set up clean at address and look pleasing within their larger, game-improvement footprint. The trailing edge is visible with the club down by the ball due to the wider sole.
Feel & Sound
The Srixon ZX4 irons felt great when hitting shots during testing. The word Rick used during his test was “phenomenal”. These irons felt explosive at impact and produced a high-pitched sound while reducing vibrations. Even shots that hit off the heel and toe felt great and performed well.

Srixon ZX4 Irons
Between the zx4 irons like the PW and AW there is a difference in loft of 6 degrees, while between the 4 and 5 irons there is only 2 degrees. Could you please tell me why the gaps in loft are not uniform. Thank you.
I see the same thing. In fact, the variances vary five times from 2 thru AW. “Usually” I’ve seen one variance in # amount of loft changes b/w irons, typically occurring b/w about the 4 and 5 iron. I would want to have several of the lofts changed to lessen the loft variances, meaning lessoning distance gaps. I’d like to know the rational.
