Yonex EZONE GT4 Golf Irons
Unlock powerful distance without giving up the refined feel of a forged iron with the Yonex EZONE GT4 Golf Irons. Created for golfers who want speed, forgiveness and confidence, the multi-material heads combine S45C forged steel with Mighty Maraging Plus face technology and vibration-dampening graphite components.
Yonex G-BRID technology refines impact feel while helping optimise weight distribution throughout the head. Progressive face materials, lofts and sole specifications provide fast performance in the longer irons with increased control towards the scoring end of the set.
EVOLVED MIGHTY MARAGING PLUS FACE
Mighty Maraging Plus technology creates a thin, resilient face designed to produce fast ball speeds and powerful distance.
The #5 to #9 irons use forged Mighty Maraging Plus steel, while the PW and AW use rolled Mighty Maraging Plus material to balance speed with scoring control.
G-BRID GRAPHITE TECHNOLOGY
G-BRID places graphite within the forged-steel clubhead to absorb undesirable vibration at impact.
This technology helps create a softer, more responsive sensation while retaining the ball speed and forgiveness expected from a modern game-improvement iron.
FORGED S45C STEEL BODY
The S45C forged-steel body provides a solid construction with clear and responsive impact feedback.
Combining forged steel with high-strength face materials allows the EZONE GT4 to produce impressive distance without losing its refined feel.
PROGRESSIVE MULTI-MATERIAL DESIGN
The #5 through AW use graphite-hybrid material and a graphite plate within the forged body. The A/S and SW use a forged body with a graphite plate.
This progressive construction allows the longer irons and scoring clubs to be tuned for their different performance requirements.
POWERFUL DISTANCE AND CONSISTENT GAPPING
The 20 degrees 5-iron begins a progressively structured set that extends through to the 55 degrees sand wedge.
Carefully selected loft, lie, bounce and face-progression specifications help create dependable distance gaps and predictable turf interaction throughout the range.
GRAPHITE OR STEEL SHAFT OPTIONS
The RK-04GT graphite shaft incorporates 2G-Namd Flex Force technology and is offered in SL, Regular and Stiff flexes.
Golfers preferring steel can select the lightweight N.S.PRO 850GH neo in Regular flex for stable performance with an accessible overall weight.
YONEX ELASTOMER GRIP
A Yonex Original Elastomer Grip completes the clubs, providing comfortable traction and useful feedback throughout the swing.
Every listed loft is available in a left-handed configuration.
