What the differences mean
At the 7-iron, the ZX7 is 32° and the ZX4 is 28.5°, a 3.5° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the ZX4 should carry roughly 10 to 14 yards further with that club, on a slightly lower, shallower flight than the ZX7. Across the 8 clubs both sets share, the ZX4 averages 2.5° stronger, with the largest gap at the 7-iron (32° vs 28.5°). The pitching wedges are 46° and 43°; the stronger one leaves a 7° jump to a 50° gap wedge, which matters when planning wedge gapping.
The sets are built differently: the ZX7 runs 3-iron to AW (9 clubs), the ZX4 4-iron to AW (8 clubs).
The ZX7 is a players iron and the ZX4 a game improvement iron, so they sit 2 steps apart on the forgiveness scale. The ZX4 is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly 10 to 25 handicaps. The ZX7 trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits roughly scratch to 10 handicaps.
The ZX7 is listed as forged and the ZX4 as cast hollow-body multi-material. Forging, as in the ZX7, is generally credited with a softer feel; casting, as in the ZX4, allows more complex cavity and weighting shapes, which is why it dominates forgiving irons. The ZX4's hollow body lets the face flex more and moves mass low and outward, usually giving higher launch and more ball speed on off-centre strikes than the ZX7, at some cost in feel. The ZX7 adds tungsten weighting, which lowers the centre of gravity and raises stability on mis-hits, helping the long irons launch.
The ZX4 came out 1 year after the ZX7, but it is a different line rather than a direct replacement, so the two were designed for different golfers as well as different seasons.
Which should you choose?
The ZX4 is the stronger-lofted set — up to 3.5° stronger than the ZX7 on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.

Frequently asked questions
Is the Srixon ZX7 stronger lofted than the ZX4?
No. The ZX4 is the stronger-lofted set: its 7-iron is 28.5° against 32° for the Srixon ZX7, 3.5° stronger and worth roughly 10 to 14 yards of extra carry.
What is the loft difference between the Srixon ZX7 and ZX4?
At the 7-iron the difference is 3.5° (32° vs 28.5°). The largest gap on a shared club is 3.5° at the 7-iron, and all 8 shared clubs differ.
Which is better for higher handicap golfers, the Srixon ZX7 or the ZX4?
The ZX4. As a game improvement iron it is the more forgiving design, suited to roughly 10 to 25 handicaps. The Srixon ZX7 is a players iron, better suited to roughly scratch to 10 handicaps.
Do the Srixon ZX7 and ZX4 have the same lie and length?
At the 7-iron, yes: both are 62° lie and 37 inches long.
