About the Ping GMax
The GMax was the maximum-forgiveness iron Ping introduced in July 2015, sold alongside the G30 rather than replacing it, and it was the first Ping iron with the COR-Eye face structure, which activates the sole, face and top rail together for up to a claimed 3 mph more ball speed. The 4- through 8-iron faces are heat treated into a roughly 40 per cent stronger Hyper 17-4 alloy so they can be cast thinner, and a concealed Custom Tuning Port connects the cavity structure to the wide sole, pushing the CG low and back for a high-MOI head. The set is built deliberately light — swing weights run C6 to C9 from the 4-iron through the 9-iron to help moderate swing speeds square the face — with lofts matching the G30 at 21 degrees for the 4-iron, 30.5 for the 7-iron and 45 for the pitching wedge, and a 56-degree sand wedge closing the 4-SW stock set. The hollow-body G700, announced in January 2018, replaced it. Ping's colour-code (dot) system sets lie angle relative to standard: gold 4 flat, brown 3 flat, orange 2 flat, red 1 flat, BLACK standard, blue 1 upright, green 2 upright, white 3 upright, silver 4 upright, maroon 5 upright. The lies below are the BLACK (standard) lies.

Frequently asked questions
What is the loft of a Ping GMax 7-iron?
The Ping GMax 7-iron has a loft of 30.5 degrees, a standard (black dot) lie of 62.0 degrees and a steel-shaft length of 37.0 inches.
When were Ping GMax irons released?
Ping introduced the GMax in July 2015 as its maximum-forgiveness iron, sold alongside the G30 rather than replacing it. The hollow-body G700 replaced it in January 2018.
Why are Ping GMax swing weights so light?
Ping built the 4-9 irons deliberately light — C6 to C9 rather than the usual D-range — to help moderate swing speeds square the face and launch the ball; the wedges return to D1-D2.
Are Ping GMax lofts the same as the G30?
Yes, club for club: 21, 24, 27, 30.5, 35, 40 and 45 degrees from 4-iron to pitching wedge. The GMax UW is 50.5 degrees against the G30's 50, its sand wedge 56 against 54, and there is no GMax lob wedge.
Finding a used set
The Ping GMax ran from 2015 to 2018 and is no longer in production, so the used market is the only source. Search eBay, 2nd Swing, Golf Avenue and the PGA Tour Superstore trade-in listings, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
- Official Ping GMax specification page (ping.com/clubs/irons/gmax, archive.org captures of 18 July 2018 and 22 August 2019, identical tables) — supplied every length, loft, lie, offset, bounce and swing weight above for the 4-iron through SW, the note that 'Lie angle is based on Black Color Code at standard length', the Power Spec loft column, and the CFS Distance steel (SR/R/S/X, 95-115g) and CFS Graphite shaft tables.
- Note on the 6-iron lie: Ping's own table prints 61.6 degrees on both captures, even though it sits above the otherwise smooth 59.2/60.1/…/62.0 progression; the published figure is recorded rather than a smoothed one. Retail tables (Morton Golf Sales, Golfstead) circulate a more upright lie column that Morton labels as the Yellow Colour Code and it is not used here.
- Ping press material 'A look inside the new GMax iron and its COR-Eye Technology' (via mygolfway.com) and GolfWRX 'Ping GMax irons: What you need to know' — the COR-Eye claim of up to 3 mph more ball speed, and the 4-8 iron faces heat treated roughly 40% stronger into Hyper 17-4.
- Golfalot 'Ping GMax Irons Review' and golftec.com 'First Look: PING i & GMax irons' (July 2015) — the July 2015 introduction alongside the Ping i irons, retail availability from 30 July 2015, the Custom Tuning Port and the positioning alongside (not replacing) the G30.
- essential.golf 'Ping G700 Irons Launched' — the G700, announced 15 January 2018, 'launched for sale as a replacement for the GMax irons', which sets year_discontinued to 2018 on the successor-announcement convention.
