Specifications

Description

The Mizuno JPX 900 Forged 4-Iron is a precision-engineered long iron that combines distance, forgiveness, and signature Mizuno feel. It’s part of the renowned JPX 900 line that introduced Mizuno’s revolutionary 1025 Boron forging process — giving you more speed without losing control.

This model sits perfectly between a players’ iron and a forgiving cavity back, offering an ideal blend for golfers who want penetrating flight, stability, and workability. Paired with the Project X LZ 5.0 shaft, this 4-iron delivers a smooth feel with a mid-launch trajectory — ideal for players who prefer control with a touch of extra height.

Key Technologies & Design Features

• 1025 Boron Forging:
  Mizuno’s unique Grain Flow Forged Boron steel provides a face that’s 30% stronger than traditional forged irons — allowing a thinner, hotter face for faster ball speeds.

• PowerFrame Design:
  Reinforces the perimeter to maximise forgiveness while keeping mass behind the hitting area for that signature Mizuno feel.

• CORTECH Face:
  Multi-thickness face construction optimises rebound across the surface, preserving speed on off-centre hits.

• Harmonic Impact Technology:
  Tuned vibration frequencies deliver the soft, solid impact sensation that defines Mizuno irons.

• CNC Pocket Cavity:
  Enhances launch conditions and stability through impact, ideal for long-iron performance.

• Project X LZ Shaft:
  Features a “Loading Zone” mid-section for smooth energy transfer and consistent trajectory control — trusted by tour players for its stability and feel.
