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.

F8 Driver Grass Laydown
F8 Irons One Length
F8 Irons One Length

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.

Golf's most advanced technology, COBRA CONNECT™, Powered By Arccos™ features electronically enabled grips in each iron. Detailed stats are recorded automatically, allowing golfers to access an in-depth analysis of their game using the COBRA CONNECT™/Arccos 360™ app on their Smartphone.

Review by Rossie - 5/9/2019

6 handicap golf who was in a serious accident two years ago who suffers with a serious bad back but loves the game to much to give it up. Fitted with the cobra f8 one length irons to keep posture the same through every swing with the irons, after a day of hitting many balls finally got it, swing like a 7 iron with every iron ball position the same and wow. Love them best irons I've hit in a long time ,great ball flight amazing distance and straight with every club, the back doesn't take as much strain so should get out more and get the handicap down. Thanks cobra for making the game easier on the back.

Review by Blaine - 10/1/2018

I play F8 standard length from 5i-7i all with a 63 degree lie. I play the one length from 8i-56 wedge, all 8i length and 63 degree lie. My 60 degree is the PUR WideLow and is 1" longer then stock but 1/2" shorter than 8i length, also 63 degree lie. This has really helped with my shot making. I play more of a single plane swing and the same lie really helps as does the one length on the 8i down. Irons look really good too.

Had a set of single length from a different manufacture before, this is my second set and what a difference in feel and an additional 10 yards from each club.

Review by Gordan R - 9/17/2018

I am playing F8 One Length clubs (from SW to Hybrid 3) now for about 8 weeks and effect is amazing. I always had problems with the consistency during a round, especially when playing 18 holes. I always got tired, because of my hemiparesis on the right hand side. It was very difficult to handle all clubs with their different weights and length through a round.
Now it's much easier for me, and I can play my handicap or better every round.
Greetings from Switzerland

Review by Jason - 9/16/2018

I recently purchased 4-pw with recoil 460 shafts. Very easy to hit. I'm fairly new to the game and one length works for me cause I dont have to worry about ball position. Plus the Arcoss is cool and can track stats.

great idea, not looking very nice though

Review by krtstk - 9/9/2018

I love the one length irons. hate the arrcos cobra connect. I would have liked to be able to get the irons with out the sensors. They do not pick up most of the shots, no wonder scores come down. I have to take a huge amount of time during the round to enter the missed shots Its a great idea but it still has a long way to go. Offer the clubs with out the Arrcos. Iam pulling the grips and putting on my golf prides and just playing golf with out running out of battery and screwing around with my phone the entire round

Review by Sway - 9/6/2018

Absolutely the best Clubs I’ve ever had in my life. It is extremely easy to hit. Don’t have to think of anything to swing. And this spin I’m getting with all the shots are amazing. Paired with the volvik s4 pro ball! It’s unbelievable the performance! Hit an easy 205 shot into par 5! If you’re playing standard length you’re crazy!

These clubs give you so much more confidence

Review by Stu - 8/29/2018

I LOVE my KingF8 one length clubs!
These clubs give me much more confidence as I address each shot because my stance doesn't change and the clubs are so forgiving.
The variety of wedges has really helped my short game too.
My handicap has reduced from 33 to 30 over just 6 rounds and I know it will continue to improve.
The Cobra Connect app is brilliant and it's built in Caddie will really show its worth as on unfamiliar courses.
These clubs have given me joy when playing golf!

Review by Jim Reed - 7/26/2018

I wasn't a believer in the single length concept until I actually gave them a try. Very happy I did. Been playing for a bout a month with my new irons and they are worth every penny. Easy to hit, more consistent. Took awhile to get use to the short irons but all in all, just excellent.

Nice Try

Review by None - 7/17/2018

You failed to meet the objective and the purpose of one length irons. On the cast set you failed to offer identical loft gaping and failed to offer an identical lie throughout the set. On the forged one length set you offered one lie but failed to offer one loft gaping throughout the set. On both sets you failed to offer identical offset on each iron. Why? Once you offer identical loft gaping throughout the entire set (and it should be 4 or 5 degrees) and once you offer personal fitting to determine a players lie (it needs to be based upon a players hand height at address) and once you offer the same offset throughout the set, you will have succeeded in making a truly one length set of irons by removing all of the variables that affect consistency. You also need to do the same for the driver and the fairway metals. Once you have incorporated the three aforementioned changes, you will have succeeded in making the best set of golf clubs ever made and possibly the highest selling set of golf clubs in history by marketing the fact that all variables that affect consistency have been removed. I am hopeful and looking forward with great anticipation that you will make the changes in the 2019 one length model.

Review by Bgh723 - 7/10/2018

I'm 70. 12 Hdcp and stopped looking for distance from my irons. My decision was trying to get consistent. These clubs are the real thing. Easy to be in the correct position no matter what the yardage is. My posture is better and I'm hitting everything in the middle of the club. (after 2 rounds and 500 balls on the range) Nothing happens with the TV clicker in your hand, so I practice. LOL. The strange thing is I picked up 5-6 yards per iron. If your looking for something different to improve your game these clubs are it. I've owned everything and I practice so if your like me don't be fearful about the investment or worried about making changes. Bryson may be a little strange be he's on to something here. By the way, forget about the 1 plane swing. Not necessary.

Review by sngldgt - 7/9/2018

Trying to get used to these one length irons. Will get there but it's going to take a little work. The concept is valid, one swing makes sense but erasing old habits won't be easy. Irons are easy to hit, distance varies a little but they feel and sound great.

Review by Mike837 - 7/9/2018

After spending some time doing some research on the one length F8 irons I purchased the 5-G steel set. All I can say is wow. Took them to the range to hit some balls to get a feel for them along with the yardages. All I can say is these irons are real easy to hit and the ball just goes straight and long. I couldn't tell you the last time I've been able to hit a 5 or 6 iron as far as I'm hitting it. Still need to get a little more comfortable with the P and G wedges when it comes to the length of the club. If you've been on the fence about trying one length all I can say is try it. My first time on the course with them and I had my best round ever there. Of course driving and putting come into play, but when it came to hitting my shot into the greens I was money with them. Very happy and can't wait to hit the links again with them!!! Also the cobra connect was easy to get started and I look forward to using it more as the GPS was matching my range finder. Only thing I don't like about the cobra connect is having to have my phone in my pocket.

Review by THOFF - 6/10/2018

I picked up a set of one-length and just finished my third round with them. I am a mid-handicapper and was looking for a new edge. These are extremely comfortable and have greatly reduced my misses. The length is the same for 7-gap and longer for clubs above 6-4. The longer Gap and PW took little time to adjust to and the longer irons are a breeze at set-up of course. I am very pleased with them and love the consistency in my game!

Review by L Rodgers - 5/11/2018

This system was included with the purchase of my new Cobra King F8 irons. I absolutely love it! I was hesitant to use it at first because I was worried about draining my phone battery. That was a non-issue, fortunately. Very easy to set up and sync each club, very easy to download and setup app on iPhone. The system works very well, I couldn't be happier! Really shows you the weak part of your game and what you need to work on. I have no doubt that this will help me take a few strokes off my handicap.

Logical design and great results

Review by Lou - 4/22/2018

The idea of a set of irons at the same length as my 7-iron appealed to my sense of logic. By coincidence, my 7-iron was the club in my bag that felt the most comfortable in my stance and the one that was most consistent for distance. Now I own an entire set of irons at the same ideal length. Out of the bag first trip to the driving range I saw 10+ yards further with the new 7-iron. Loft and trajectory on the wedges were superb. Around the greens I'll need to work on the oddity of chipping and pitching with this length club. Feels funny but I'll practice and adapt. Even the long clubs, 4 & 5, are a comfortable length since they are the same length as my normal 7. The result is better control. The technology and design make sense, club loft and lie is calculated for ideal shots at the same length so each club behaves as it should and I'm enjoying a standardized stance and swing. Next step is to setup my Connect app with my sensor equipped clubs!

Review by Chris P - 4/21/2018

Switched over from sterlings when the F8s came out. Glad I did, the long irons fly higher and more consistent, the feel is awesome, like literally some of the best feeling clubs I’ve played. I’ve got the 5-GW and I now love 200 years aproach shots, a bogey used to be my best case scenario from that distance. Well done cobra.

Review by Drew - 4/19/2018

Just recently had these clubs, i have to say i am thus far very pleased. I was a little apprehensive about changing to One length, but finding the switch very easy. The ( we will call them long irons) are a joy to hit, no long feeling concerned about the extra length, and I am finding no problem getting them up in the air. The (we will call them short irons) are a little strange at first, being 2inch longer, but i have found them a joy chipping around the green. Early days, but glad i took the plunge.

This is my second set of cobra one lengths. Love these clubs. Took about 3-4 rounds for me to mentally get used to them but after that I’ve played my best golf ever. I am much more consistent and they are much better on my arthritic knee. The 2017 set was great, the 2018 set even better.
