Cobra 2021 King Radspeed (5-S) Graphite Irons

A breakthrough in RADIAL WEIGHTING technology is met with the first 3D printed medallion, creating our fastest, most stable, and technologically advanced irons to date.

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.

EXTREME HEEL & TOE 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.

TUNED RAD WEIGHTING
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.

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

FORGED PWRSHELL FACE
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.

CARBON FIBER TOPLINE
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.
