Gain distance on the course with driver level COR in Mizuno’s JPX-900 Hot Metal Steel Iron Set. This collection of clubs utilizes Chromoly 4140M which is 15% stronger than 17-4 pH stainless steel. What’s great about using Chromoly 44140M in the construction of these irons is that you can customize your loft and lie without losing COR. It also maintains ball speed across more of the face.
Superior Frame Design
The face’s cup face and CORETECH multi-thickness design allows the ball to increase speed off the face while also increasing the sweet spot and COR area. Extra attention was put into the frame's design too. To increase MOI, more weight was able to be placed around the perimeter from the lighter materials used. The frame’s Power Frame Geometry allows the club to make a powerful sound at impact for improved responsiveness from its Harmonic Impact Technology.
