A mid-sized, one piece grain flow forged iron that comprehensively ends the normal trade-off between precision and distance. Produced from a stronger Boron infused steel billet - the JPX900 forged boasts a milled pocket and new multi thickness face for increased ball speeds over a wider area. More compact than its predecessor the JPX900 forged continues to break the rules with its incredible combination of forged feel, forgiveness and ball speed.

• Steel reinforced with trace amounts of boron is 30% stronger frees discretionary weight to allow US to make the face thinner with extreme geometry
• The JPX900 forged pushes the potential of boron infused steel to new levels with a multi-thickness face designed for the fastest ever ball speeds from a gff iron across the entire face of the club
• CNC milled pocket cavity extended in both directions to redistribute 21.5 grams to reduce distance loss from off center hits
• The shorter irons (8-gwg) are scaled back in size for precision and control where most needed
• Project x lz 5.5 shaft
