KING SPEEDZONE ONE LENGTH IRONS
The ONE Length counterpart of the SPEEDZONE irons are designed to 7-iron length (37.50") through the set to promote one repeatable setup and swing between clubs for more consistency and accuracy.
AND SWING.
Each ONE Length iron is designed to match 7-iron length and weighting to deliver one repeatable swing, and consistent trajectories and gapping throughout the set.
CARBON FIBER TOPLINE
Carbon fiber has a higher strength to weight ration 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.
