KING SPEEDZONE Irons
The SPEEDZONE irons feature a breakthrough in performance with our first ever Carbon Fiber Topline, delivering an ultra low CG for maximum speed and launch.


SPEEDZONE. FOUR ZONES OF OPTIMIZED SPEED.




CARBON FIBER TOPLINE
Carbon fiber has a higher strength to weight ratio than steel, and saves 3 grams to lower the CG and maximize ball speed.

FORGED PWRSHELL FACE
A forged PWRSHELL face insert features a 35% larger Sweet Zone area, and a 8% deeper undercut to enhance ball speed and launch across the face.

SPEEDBACK SHAPE
Extreme heel and toe weighting creates a lower CG and a higher MOI than most traditional iron shapes allow.

CO-MOLD MEDALLION
A lightweight medallion features aluminum, TPU, and acrylic foam that work together to damp vibrations for excellent sound and feel.

Cobra Connect
The SPEEDZONE family of clubs each feature an Arccos embedded grip sensor that pairs with the Arccos Caddie app on your mobile device. Arccos Caddie leverages golf's richest data to help players make smarter shot making decisions.
