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.

I made the best choice of my golfing life
I read and watched all the you tube evaluations, I had to make my on evaluation so I took the plunge. Best move of my life , I am a 3 handicap at 73 yrs old and with these clubs I feel it will be even lower. I gained a whole club in length in yardage , sweet spot so easy to hit . My secound round with these shot 1 under and did not miss a green in regulation. I play on one of the senior tours and have been for 15 yrs. so this is not a rookie evaluation , thanks Rock Bottom .

Just what I was looking for
I'm a scratch golfer at 61 years old. I am beginning to lose some distance as I age. These irons (replacing TM RSI1) got me the 1/2 club distance I was looking for. The unexpected positive is the off center hits are maintaining the distance as well.
ProsOff center hits are maintaining distance to target

These clubs are amazing!
These clubs are amazing. I?m a huge fan of Cobra clubs as they are very forgiving. I have swung several different clubs and felt like these are the best clubs on the market and specially for the price on Rock Bottom Golf!
Pros* Cobra Connect * Look Fantastic * Very Forgiving * Great Feel * Good Distance on missed hits
Cons* No Sand Wedge

Great improvement over the F7 one lengths
I really like the f7 OL, but they had their quirks, long irons flew too low, short irons flew too high. But the F8's really took care of those issues. I am a one length player for life now. Looking forward to the F9 version next year when the prices come down a bit.

One setup, one swing is not just a marketing gimmick. Trust'em and crush'em I say.

ProsOne setup one swing really works. Great feel and can still work the ball if needed.
ConsShort irons take a while to get used to but not some much a con as it is a warning.

As advertised
Been golfing for 30 years, not very good after all that time. The idea of one length clubs made sense. My advice is to stay on the range for a while with them. I'm still struggling to get over the mental aspect. I have to keep telling myself I have a 7 iron in my hand. Topping the 5, chunking the GW. The connect function in the grips is cool but (not totally accurate) you have to keep your phone in your pocket which I dont like. Removing a star for the connect function (only a 90 day trial included).

Excellent product
This irons set help you to be more accurate to be on the green.
This set is easier to hit than my previous one.
I like it. I improve my game by at least four shots per 18 holes.

Not sure about the gap wedge
I really wanted to go 4 nd 1/2 stars.
I'm really happy with this set 5 though PW. Easy to hit, a little difficult to "work" but that's actually what I prefer in an iron set.
I will say I'm not sure about the GW. It's designed much more like a "wedge" and a lot less like the rest of the set.
My concern is that it's only 49 degrees, which for me means I'm much more likely to hit it for full shots.
I think I may have preferred it to look like the PW.
ProsCobra is the best. They actually sent 6 extra "Cobra Connect" sensors with my set, plus a putter sensor. I love Arccos, I love Cobra.
ConsAgain the Gap Wedge is designed like a sand wedge or lob wedge. Normally I hit full shots with my Gap Wedge. I think I would have preferred it to be more like the PW. Others may disagree.
