King F8 One Length

COBRA’s first ever connected set of ONE Length™ irons ill improve your game. Carbon fiber tuned PWRshell™ Technology delivers superior feel and long, towering shots. COBRA Connect Technology proves the performance.

Cobra Connect Powered By Arccos™


Cobra Connect sensors are now included in every club in the F8 family. You get GPS access to more than 40,000 golf courses to help track your game. The sensor records each swing, displaying results on your smart phone. With more access to data, you track your round, improve where you need it, and share and challenge your friends.

One Length™ Set Makeup

COBRA ONE Length™ irons are each re-engineered to match 7-iron weighting and length to deliver more consistent trajectory and distance gapping throughout the set.

Forged PWRSHELL Face™ Technology

A thinner, variable thickness L-Cup face design enhances the active Sweet Zone™ for faster ball speeds and higher launch across all points on the face.

Carbon Feel Technology

For the first time ever in an iron, a lightweight carbon fiber medallion supports a thinner face while delivering improved sound and feel.

Lower Profile Design

A lower profile clubhead design improves aerodynamics and lowers CG for higher launch and more clubhead speed.

Tecflo™ Progressive Set Technology

Advanced construction technologies combine to create the ultimate progressive irons. Progressive hosel lengths and wider soles (4-6) perfect trajectory and launch throughout the set.

Progressive Spin Technology

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 deliver extra spin for shots around the green.

Great deal and even better clubs
Hit my clubs for the first time this past Sunday. A real game changer. Anybody thinking about them there the real deal. Worth every penny. And the whole buying process was perfect.

Absolutely love these
Was very intrigued by the idea of one length irons but having no way to demo them I actually bought a new set of Taylormade M2s this season. After a few months seeing zero progress in my ball striking I decided to go OL route. I've had these for about 6 weeks now and I can tell you my confidence over the ball has never been higher. And I'm strike the ball as good as I ever have. I absolutely love the 5h. Will be adding a 3 or 4 next season. I'm not sure why the one length concept hasn't caught on in a bigger way, but I hope Cobra continues to push this product line because I see it as a total game changer, especially to new players.
ProsSuper easy to hit. One set up, one swing.

Very happy with these clubs
It does take a couple rounds to get used to them - or a few buckets at the range. But I have never hit a 5 iron so well. Even mishits are decent which was not the case before.

Best irons I’ve ever owned
Forgiving and easy to hit. The one length was a concern of mine but I’m glad I decided to give them a try. My swing is more consistent and my distances are gapped better to fit my game. If you struggle with regular irons these cobra F8 one length irons just might fix some of your game issues.
ProsEasy to hit Same length takes the guess work out of where to hold your clubs Miss hits still keep there distance and don?t hurt your hands Cobra connect gives you instant feedback Nice at address and very easy on the eyes
ConsI wish the cobra connect from Arccos was free all the time not just the first year
