Srixon’s ZX4 Irons featuring V-shaped sole

Like and Follow Golf Oklahoma


Srixon’s ZX iron series has been completed with the introduction of the game-improvement medium profile ZX4 irons featuring forged faces, V-shaped sole and hollow construction.

Srixon has introduced the game-improvement ZX4 model, the final member of the ZX iron family joining the ZX7 and ZX5. The newbies have the widest sole with the most offset of the series as well as the longest blade of the three.

Each of the ZX4s has a hollow clubhead with the long and mid irons having added tungsten to get the center of gravity closer to the sole for higher launch. The face is forged from HT1770 steel which is strong and therefore can be thinner resulting in more flex at impact and better distance. This lightweight construction works well with the milled cavity design the company calls MainFrame that is expressly designed to increase COR.

The Srixon V.T. Sole, which we have always liked, is wider than in the ZX7 and ZX5 but still does the job of minimizing turf interaction as it has done on other models.
