Experience powerful distance, forged feel and dependable forgiveness with the Yonex EZONE GT4 Golf Irons. Designed for golfers seeking increased ball speed without sacrificing control, these advanced game-improvement irons combine an S45C forged-steel body with Mighty Maraging Plus face technology and Yonex G-BRID construction.
The multi-material design places graphite components within the clubhead to improve impact feel and optimise weight distribution. Progressive face materials and carefully engineered lofts create powerful performance through the longer irons with improved control throughout the scoring clubs.
The EZONE GT4 Irons feature evolved Mighty Maraging Plus face technology to generate increased resilience and efficient energy transfer at impact.
The #5 to #9 irons use a forged Mighty Maraging Plus steel face, while the PW and AW use rolled Mighty Maraging Plus material. This progressive construction balances distance, ball speed and control throughout the set.
Yonex G-BRID technology places graphite within the forged-steel head to absorb unwanted vibration and refine the sensation at impact.
This graphite-hybrid construction helps produce a more responsive feel while contributing to the carefully optimised centre-of-gravity location.
The S45C forged-steel body provides a solid, refined foundation with the responsive feedback associated with forged golf irons.
Combining forged steel with graphite plates and a high-strength face allows the EZONE GT4 to deliver distance and forgiveness without producing an excessively harsh impact sensation.
The #5 through AW use a graphite-hybrid component and graphite plate within the forged head. The A/S and SW use a forged-steel body with a graphite plate.
This progressive construction allows the performance of each club to be tuned according to its intended role within the set.
Strong lofts in the longer and middle irons support powerful distance, while progressively increasing bounce and face progression improve control through the shorter irons and wedges.
The carefully structured set provides consistent distance gaps from the 20 degrees 5-iron through to the 55 degrees sand wedge.
The Yonex RK-04GT graphite shaft incorporates 2G-Namd Flex Force technology and is available in SL, Regular and Stiff flexes.
Its lightweight construction provides a responsive feel and helps golfers generate clubhead speed while maintaining control through impact.
The Yonex Original Elastomer Grip provides comfortable traction and responsive feedback throughout the swing.
All listed iron lofts are also available in left-handed configurations.
