MainFrame is a variable thickness pattern of grooves, channels, and cavities carefully milled into the backside of ZX4 Mk II, ZX5 Mk II, and ZX Mk II Utility Iron faces that maximizes flex at impact. MainFrame not only boosts COR, it also repositions mass away from the face and into the toe and sole for a lower Center of Gravity. This creates more than just faster ball speed, but also more consistency and forgiveness, enhancing all aspects of your Iron play, shot for shot.

Our dynamic Tour V.T. Sole helps maintain clubhead speed through impact for clean strikes across fairway, rough and sand—even if you contact the turf slightly behind the ball. A higher bounce on the leading edge prevents digging; then, a lower bounce on the trailing edge curves away from the turf, so you can still manipulate face angle for maximum workability.

The 4i–7i feature wide grooves, ideal for longer shots in all conditions. The 8i–AW have deeper, closer set grooves which cut through grass and debris to enhance spin on approach shots. Laser milling between each groove, on every loft, enhances friction in all conditions.

The best of both worlds. The ZX5 + ZX7 set is an uncompromising combination of distance in your long Irons and workability in your short Irons. Ordered as custom, suggested sets are 4i–6i or 4i–7i in ZX5, and 7i–PW or 8i–PW in ZX7. Other combinations are also available.

This combo set is the most popular with our professional tour staff due to its extremely forgiving long Irons and highly workable short Irons. ZX Utilities are available in 2i–4i and usually selected by players seeking more forgiveness over traditional long Irons.

More forgiveness to help score your best. This combo set of cavity back short and hollow long Irons is perfect if you prefer to attack the pin head-on. Ordered as custom, suggested sets are 4i–6i or 4i–7i in ZX4, and 7i–PW or 8i–PW in ZX5. Other combinations are also available.
