King F7 One Length Irons

The KING F7 ONE Length irons make their debut as Cobra’s first ever single-length iron set. Inspired by PGA Tour Professional, Bryson DeChambeau, The KING F7 ONE utilizes the same TECFLO constructions as the KING F7 along with PWRSHELL Faces and Precision Milled Grooves. However, the KING F7 ONE features constant 7-iron lengths throughout the set and each head has been re-engineered for proper geometry to deliver optimized trajectory and distance gapping from long irons to wedges. The end result? A simpler, easier way to play.


Proper setup includes foot positioning, spine angle and ball position, and many other variables. These variables change as you switch between longer and shorter length clubs, causing more room for error. With one setup and one swing you can simplify the entire process. Every player has their favorite club and for many, it’s a 7-iron. With Cobra’s One Length irons, you will find new confidence in your game, allowing you to play any iron in the bag as if it were your trusty 7-iron.

KING F7 irons utilize Cobra’s TECFLO construction to deliver a set that deploys advanced construction technologies to optimize the performance characteristics of each iron, with new PWRSHELL faces for added distance, precision and forgiveness and T.O.P Technology for lower CG.

The PWRSHELL face of the F7 irons promotes a thinner, stronger face and sole structure re-engineered for speed. Using a high strength 17-4 stainless steel L-Cup face design, Cobra has produced a larger Sweet Zone delivering distance, more forgiveness and ultra-precise irons.

Premium Nickel chrome plating provides better aesthetics and durability for great looking and longer lasting irons, all while 100% CNC milled grooves improve groove structure. The CNC grooves increase spin and optimize trajectory throughout the set. The result is improved control and workability giving you added confidence when you’re attacking the pin.

This lower and centered CG placement creates more precision without sacrificing forgiveness.

Progressive Spin Technology is utilized throughout the Cobra F7 One Length irons. V-Grooves on the 4-6 irons reduce spin, U-Grooves on the 7-PW optimize spin, and wedge-spaced grooves on the GW-SW produce extra spin for shots around the green.

Multiple construction technologies flow together to create the ultimate progressive irons. Each club in the set is designed to perform differently, optimized for performance to help golfers hit more greens and hit it closer to the pin.
