Ping's GMax irons are built around what the company are calling COR-Eye technology, a new design that increases flexing across the whole face to generate faster ball speeds for more distance and forgiveness.
COR-Eye activates the sole, the face of the club and the top rail to allow the face to flex more and therefore increase ball speeds by up to 3 mph over previous Ping models.
COR is a measure of ball speed from the face and Ping's technology works across the whole face so faster ball speeds are maintained across a larger area, meaning the clubs are more forgiving with even off centre hits resulting in longer and straighter shots.
The stainless steel faces of the GMax 4-8 irons have been heat treated in a specialised process that strengthens the material by approximately 40%, with the resulting Hyper-17-4 alloy allowing the faces to be thinner, by 31% at the perimeter, thereby allowing for greater flexing and faster speeds.
The GMax irons boast a new cavity structure concealing Ping's Custom Tuning Port that is connected to the sole of the club. This deeper position within the club head moves the centre of gravity low and back to increase MOI for greater forgiveness, higher launch and increased accuracy.
The GMax irons have distance optimised lengths and lofts whilst maintaining an efficient gapping between the irons to promote distance control and produce the higher trajectories required to hit and hold more greens. Trajectory is also influenced by longer blade lengths and increased offset which ensures a higher maximum shot height as well as improving forgiveness.
Turf interaction is improved by an enhanced leading edge and more trailing edge relief to refine the bounce and ensure that the irons are extremely playable in all conditions.
Playability is also improved with a progressive swingweight throughout the set to help players who struggle to square the club at address. The longer 4, 5 and 6 irons have a lighter swingweight of C6, C7 and C8 respectively, helping golfers square the club face at impact to produce longer and straighter shots.
The GMax irons come with the CFS Distance Steel and CFS Graphite shafts as standard, Ping also offer after-market fitted shaft options of Dynamic Gold, Project X, XP 95 and Nippon Modus 105 at no additional cost.
