KING F8
  • What It Is

    The industry's first electronically enabled set of ONE Length™ irons. Every iron is designed to match 7-iron length and clubhead weighting.

  • Who It's For

    5 to 25 handicap golfers with moderate to higher swing speeds seeking a forgiving distance iron with enhanced feel.

  • Why we made it

    The KING® F8 ONE Length™ irons have been re-engineered using progressive clubhead constructions and flighted shaft technologies to deliver improved trajectory and feel through the set.

IMPROVED CLUBHEAD DESIGN

Progressive clubhead construction features progressive sole widths and hosel lengths for optimized trajectory and feel from the long irons to the wedges.

FLIGHTED SHAFT TECHNOLOGY

Graphite and steel shafts feature adjusted flex profiles through the set for higher launching long irons and short irons with lower, more controlled trajectories.

7-IRON CONFIGURATION

Each KING® F8 iron is configured to match 7-iron length, head weight and swing weight to promote consistent feel through the set.

ONE LENGTHTM
One Step Further

Flighted Shaft Technology.

COBRA® has teamed up with its shaft partners to engineer unique designs that optimize ONE Length™ performance. Utilizing flighted shaft technologies, the graphite and steel shafts feature adjusted flex profiles that make the long irons play softer and launch higher, and the short irons play stiffer and launch lower.

Higher Launch Lower Launch

Long Irons Made Easy

Featuring a lower profile clubhead design with wider soles in the 4-6 irons, the CG is moved lower and deeper to deliver higher launching trajectories. Paired with an optimized E9™ Sweet Zone™, the KING® F8 ONE Length™ long irons are faster and longer, while maintaining the simplicity and accuracy that players find appealing with the ONE Length™ set makeup.

Long Irons

A Short Game You Can Brag About

The key to a better short game is knowing your wedge distances. The KING® F8 ONE Length™ wedges give you more confidence with one setup and one swing, while an improved clubhead construction promotes lower, more controlled trajectories. The result is more consistency, more predictable distances, and closer birdie opportunities.

Short Game

Re-Engineered
for Consistency

The KING® F8 ONE Length™ irons feature cutting-edge technologies that make them even easier to hit and more consistent than ever before.

Simplify Your Golf Game

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.

Re-Engineered

One Swing For Every Shot

In a traditional iron set, certain variables of the swing change as you switch between your longer and shorter irons, causing more room for error. With one setup and one swing, you can simplify the entire process and swing every iron in the bag with confidence like it's your trusty 7-iron.

Better Distance Gapping

Studying real-world yardage gaps using Arccos data, many players have distance overlap with their variable-length long irons. ONE Length™ long irons provide more confidence at address, promoting more consistent ball striking and carry distances.

Tighter Shot Dispersion

Having a more comfortable, repeatable swing that is shared between your long irons and short irons promotes more consistent contact. The result is more greens-in-regulation, tighter approach shots and more birdie opportunities.

More Accurate Short Game

If there are weak points in your short game, you are not alone. The KING® F8 ONE Length™ wedges provide a seamless transition from your long and mid irons allowing you to set up to every shot with confidence and attack the pin with more consistency.

Love the one length cobra irons
Rating
Review by Todd T - 6/1/2019

I really love my new one length Cobra f8 irons. Hitting a 4-iron that is 7-iron length gives me more confidence that I am going to hit the ball well. At this point, I can’t see myself going back to multi-length irons. #OneLengthForLife

Great Concept

Review by Denard - 5/3/2019

These clubs are so comfortable to swing. Very easy to adapt to the one length concept. Had used all kinds of irons before but this is the best set of irons I've ever owned.

Review by Tony - 5/3/2019

I purchased the F8 one length irons 5 thru approach wedge and needed a 4 iron as I'm not a big hybrid guy. Love the four iron as it sounds out my set and provided the extra distance and accuracy I need. Previously a Callaway guy, this is my first encounter with Cobra Golf and I am totally impressed.

Review by Z - 4/26/2019

I started with a wedge, hit it pure and decided to expand. Like others on here I was dipping my toe in the water. I added a couple one-length's at a time for trial runs. I find them easy to hit. They are long and I am of course now buying a set of irons piece meal. Save yourself the trouble and just commit. It's worth it.

F8 single length 4 iron
Rating
Review by Billy5wood - 3/29/2019

I own a set of F7 single length 5 thru gap wedge irons. I was looking for the F7 single length 4 iron to complete my set. Since the F7 4 iron was unavailable I decided to purchase the F8 4 iron. And what a difference . I love my F7 clubs but I find the trajectory in the 5 and 6 irons to be a little low. The trajectory on the 4 iron is significantly higher than that of the 5 iron. I plan on switching out my F7 5 and 6 irons for the F8 5 and 6 irons. The technology just keeps getting better.

F8 One Length
Rating
Review by JRaymond71 - 3/25/2019

I purchased the F8 One Length hybrids last year, and really like them. So this year I got the F8 One Length irons. I have always had trouble hitting my long irons, and the concept appealed to me. And what a great improvement to my game! I am a big fan. For those of you who are wondering, I can't control the trajectory as much as with conventional irons, but for a mid handicapper, consistency is more important to me. I did have a major mistake due to the technology though. Went for my 9, grabbed my 6 and absolutely flushed it! Oh well, it was a sweet hit. I will watch closely to see if any other major manufacturers come on board, but thanks Cobra, you made golf fun again.

No adjustments needed

Review by Grumps - 3/23/2019

Gone are the days of being able to hit the long irons but not the short or vice versa. Now, if I can hit one I can hit them all. Everything, from length to feel is identical. Concept of simplification has become reality.
I’m almost 70 years old and no longer have the energy to practice with all my irons, now I don’t have to. Thank you Cobra!

Review by Lifetimetattoo - 11/30/2018

I bought 2 single length wedges to match my irons. I found after being accustomed to single length irons, I was blading my wedges on full swings. I play my irons +3/4 so it’s pretty weird having a lob wedge the same length as a standard 6 iron, but oddly enough, it hasn’t affected my ball striking in any negative way. Other than loose ferrules, they’re pretty great. If you have single length clubs, I wouldn’t hesitate to get irons for the set. The consistency is very confidence building.

Club hits well and the one length works well. Easy to switch from club to club because the length is the same.

Review by George - 3/12/2018

I purchase the F8 one length 5 iron with graphite shaft to test before I bought the whole set. I currently own the F7 steel shaft and wanted s lighter shaft.

The new F8 5 iron flies higher!.

Thanks Cobra for reintroducing the one length concept
