KING RADSPEED ONE Length Irons
The RADSPEED ONE Length irons feature our most advanced technologies to date, including RADIAL WEIGHTING, and the first-ever 3D printed medallion to create our longest, fastest, and most forgiving ONE Length irons.


RADICAL ENGINEERING.
The RADSPEED irons feature our most advanced technologies including, RADIAL weighting, PWRSHELL, and a 3D printed medallion, to create our most innovative and highest performing irons yet.



RADIAL WEIGHTING
10g and 3g of mass is positioned on the toe and heel extremities to create the best combination of speed, low spin and stability for optimized performance.

A 10g weight positioned low and in the toe area centers the CG and adds stability for more distance and forgiveness on off-center hits.

RAD TECHNOLOGY
3D printing offers unlimited complexity in design, allowing us to produce an intricate lattice medallion structure that saves weight and fine-tunes feel.

A forged PWRSHELL face insert is made of a thin 17-4 stainless steel, and is designed to increase flex on the face and the sole for faster ball speed and higher launch.

A carbon fiber topline saves 2 grams to lower CG and increase MOI. An all new black carbon finish creates the illusion of a thinner topline for a sleeker look at address.




And Swing.
Each ONE Length iron is designed to match 7-iron length (37.5") and weighting to promote one repeatable set up and swing, and consistent gapping and trajectories through the set.



COMPARE IRONS
- SHAPE: Slightly oversize
- SOLE WIDTH: TRADITIONAL
- PERFORMANCE: High launch and forgiveness in a traditional, variable length setup
