Lofts differ on 8 of the 8 clubs the two sets share. A lower point is a stronger loft.

What the differences mean

At the 7-iron, the ZX4 Mk II is 28.5° and the ZX5 Mk II is 31°, a 2.5° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the ZX4 Mk II should carry roughly 8 to 10 yards further with that club, on a slightly lower, shallower flight than the ZX5 Mk II. Across the 8 clubs both sets share, the ZX5 Mk II averages 1.4° weaker, with the largest gap at the 7-iron (28.5° vs 31°). The pitching wedges are 43° and 44°; the stronger one leaves a 7° jump to a 50° gap wedge, which matters when planning wedge gapping.

The sets are built differently: the ZX4 Mk II runs 4-iron to SW (9 clubs), the ZX5 Mk II 3-iron to AW (9 clubs).

The ZX4 Mk II is a game improvement iron and the ZX5 Mk II a players distance iron, so they sit one step apart on the forgiveness scale. The ZX4 Mk II is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly 10 to 25 handicaps. The ZX5 Mk II trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits roughly 5 to 15 handicaps who want extra distance from a compact head.

The ZX4 Mk II is listed as cast hollow-body multi-material and the ZX5 Mk II as forged multi-material. The ZX4 Mk II'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 ZX5 Mk II, at some cost in feel.

Both sets were introduced in 2023, so this is a choice between two models from the same lineup rather than an upgrade: Srixon designed them to sit side by side for different players.

Which should you choose?

The ZX5 Mk II is the weaker-lofted set — up to 2.5° weaker than the ZX4 Mk II. That trades raw distance for a steeper landing angle and more predictable stopping power into greens.
