Srixon ZX Irons Specs: ZX4, ZX5 & ZX7 Mk II Loft & Lie Complete Chart

Here are the factory specs for the Srixon ZX Mk II iron family. Use this chart to compare lofts, lie angles, lengths, and offset before your next fitting. Stop point: if you are ordering custom, take these numbers to your fitter and confirm lie and shaft length adjustments are right for your swing. If you are blending models, check the lofts carefully – the gap between ZX4 and ZX5 at the same iron number is roughly 2°, which can create distance holes or overlaps.

Offset is not published for the ZX4 Mk II. Expect larger offset than ZX5 for added forgiveness. Swing weight also not supplied in factory data.

Technology: Hollow-body construction with a thin, forged steel face, wide sole, and strong lofts.

Intended player: High-handicap to mid-handicap golfer who needs extra launch, distance, and off-center hit forgiveness.

Making the Specs Work for Your Bag

Take two minutes to run through this checklist before ordering. It prevents the most common mistake – ending up with a set that gaps poorly or does not fit your swing.

What you need: Your current iron specs (loft/lie/length from the head or a previous fitting) plus a rough idea of your 7-iron carry distance.

Step 1 – Pick your model based on feel and forgiveness.

If you are a low-handicap player who likes a compact head, ZX7 is the fit. Mid-handicap players looking for speed and help should go ZX5. High-handicap or anyone who struggles with launch and off-center hits belongs in ZX4.

Step 2 – Check the lofts against your current set.

Write down the loft of your current 7-iron and compare it to the ZX7 (32°), ZX5 (31°), or ZX4 (28.5°). A difference of 3° or more changes your carry distance by roughly 6–8 yards per club. If you are moving from a traditional set (e.g., 7-iron at 34°) to ZX4, expect your 7-iron to fly one club longer than before.

Step 3 – Plan your gapping, especially if blending.

Many players combine ZX5 long irons (5i–7i) with ZX7 short irons (8i–PW). That creates a 2° gap between the same iron number in each model (ZX5 7i at 31°, ZX7 7i at 32°). To maintain consistent 4° steps, you may need to bend the ZX5 set 1° weak or the ZX7 set 1° strong. If you cannot decide, stick with one full set – blending requires a launch monitor session to verify.

Step 4 – Confirm length and lie.

All three models share similar lie angles per club number. ZX4 is ¼” longer in some clubs (4i at 38.75″ vs ZX5 38.5″). If you are between 5’8″ and 6’2″ with standard arm length, stock length works. Outside that range, get a static fitting (wrist-to-floor measurement) before ordering. Stop point: If you cannot check your wrist-to-floor measurement at home, book a 15-minute fitting at a shop – do not guess length adjustments yourself.

Verification step – Test the gap after you build or adjust.

Hit at least five shots each with your 7-iron and 8-iron on a launch monitor. The carry distance difference should be 10–12 yards. If it is less than 8 yards or more than 14 yards, the lofts need a tweak. Also check that your average face impact is centered – if you are consistently off the toe, the lie may be too flat.

Common failure mode – ordering ZX4 without checking your wedge lineup.

The ZX4 PW is 43°, roughly 5° stronger than a traditional pitching wedge (48°). That leaves a large gap between the PW and your sand wedge (typically 54–56°). You will either need to bend the PW weaker, add a dedicated gap wedge around 48–50°, or accept a 15-yard hole in your short game. Plan for this before you order, not after.

Key Takeaways

• Loft gapping: ZX7 runs most traditional (PW 46°), ZX5 is about 2° stronger per club, and ZX4 is the strongest (PW 43°). If you blend sets, check distance gaps at the top end.
• Offset progression: ZX7 has the least offset (1.7–3.5mm), ZX5 slightly more (2.3–4.2mm). ZX4 offset is not published but is noticeably larger to help square the face at impact.
• Length and lie: All three models share the same lie angles per club number. ZX4 is ¼” longer in some clubs. Swing weight varies: D2 for ZX5, D3 for ZX7; ZX4 swing weight not supplied.
• Who should pick which: ZX7 for low-handicap players who want workability. ZX5 for mid-handicap players who need speed and forgiveness. ZX4 for high-handicap players or anyone who wants maximum launch and straighter shots.
• Verification rule: Loft, lie, and length specs can be adjusted during a custom fitting. Varies; verify locally with a certified Srixon fitter to match your posture and swing plane.

FAQ

Are these the standard Srixon ZX Mk II specs or can I order them custom?

These are the factory standard specs. All lofts, lies, and lengths can be adjusted through Srixon’s custom program or by a clubfitter after purchase.

Can I mix ZX5 and ZX7 irons in a combo set?

Yes. Many players pair ZX7 short irons (8–PW) with ZX5 mid or long irons (5–7) for a blend of feel and forgiveness. Be aware of the 2° loft gap between models at the same iron number – you may need to bend one set to maintain consistent spacing.

Why doesn’t the ZX4 table have offset numbers?

Srixon does not publish offset for the ZX4 Mk II in its official spec sheet. Typically, game-improvement irons have offset in the 4–6mm range. Confirm with a retailer if you need exact measurements.

What shaft lengths are stock?

Stock lengths vary by shaft brand and model. The lengths in the tables above are for the stock steel shaft option. Graphite shafts may play slightly longer depending on the manufacturer. Confirm with your fitter before ordering.
