KING F9 Driver
  • What Is It

    SPEEDBACK Technology is a revolutionary advancement in engineering, creating the first driver to successfully combine an aerodynamic shape with a low center of gravity to optimize club speed and ball speed for maximum distance.


    Three different models (9.0, 10.5 and 12.0) feature 8 adjustable lofts and a front to back adjustable CG system, allowing golfers of all abilities (Tour to 25 handicaps) to find the perfect launch & spin configuration for their game.

  • Why we made it

    Our engineers identified a common problem in today's driver designs: to get optimal aerodynamic properties, you have to sacrifice other parts of the design. SPEEDBACK™ Technology is a revolutionary breakthrough in driver engineering and is the first to combine a streamlined, aerodynamic shape with a low center of gravity. Paired with the only CNC milled driver face, it delivers substantial improvements in club speed, ball speed and distance without sacrificing forgiveness.

The Ultimate
Formula for Speed.

Longer starts with Faster. Faster starts with SPEEDBACK, a revolutionary advancement in low CG, efficient aerodynamics, and precision CNC milled face technology that delivers the Ultimate Formula For Speed.

KING f9 Speedback

Speedback Aero Design.

SPEEDBACK Technology delivers Cobra's most aerodynamic club shape which utilizes rounded leading edges, a raised crown, a raised skirt and a raised tail. This design streamlines the clubhead to promote an uninterrupted flow of air from the leading edge to the tail, to reduce drag and increase club speed.

KING F9 Driver Aero

Optimized Aero and Low CG.

A low CG structure comprised of titanium and tungsten moves the CG low and deep, creating a more efficient transfer of energy to the ball for optimized launch and spin, while maintaining an aerodynamic shape.

KING F9 Driver Low CG

CNC Precision
milled face.

In an industry where everyone claims to have a fast driver face, ours is the only one that is CNC milled. A process that is up to 5 times more precise than conventional hand-polished driver faces, CNC milling delivers our thinnest and hottest face design repeatedly on every driver.

CNC Milled face driver


CNC milling allows face thicknesses and curvatures to be controlled to tighter tolerances, ensuring consistent performance across every driver manufactured.


CNC milling is an industry leading technology that took two and a half years to perfect. We are the only company to feature CNC milling in both our driver and fairway faces.


CNC milling yields more precise face thickness compared to manual hand polishing, allowing us to design a thinner and faster conforming face.

Speed Tuned

Dual Roll adds distance to your drives by reducing the gear effect that negatively impacts launch and spin on shots hit high and low on the face. Each driver is SPEED TUNED with optimized top and bottom curvatures to tune launch and spin for different swing speeds and attack angles.

SPEED Tuned Performance

Dual Roll Technology.

Bulge and roll curvatures are CNC milled into the face following exact specifications in the 3D CAD file design to ensure consistent performance in every driver we manufacture.

1. Top Roll Curvature

The top half features more curvature than the bottom half of the face to promote higher launch with reduced spin on shots hit above the centerline.


The axis is tilted at a 7 degree angle to account for the amount of toe droop that occurs during a typical swing.


The bottom curvature is SPEED TUNED to optimize the loft of each driver head (9.0, 10.5, 12.0 to 12.5 women's & junior's) to maximize launch and spin for different swing speeds and attack angles on shots hit below the centerline.

Dual Roll Technology


Three different horizontal bulge curvatures are CNC milled into the face to control loft and face angle on the heel, toe and center areas. Having perfected bulge curvatures is crucial to minimize the gear effect on shots hit on the toe and on the heel so the ball ends up closer to the target line.

King F9 Bulge

E9 Technology

E9 Technology is a variable thickness structure designed in an elliptical shape (along 9 different points) that expands the SWEET ZONE across a typical miss-hit pattern that ranges from the low heel to high toe areas.

King F9 E9 Face Tech

Straighter, More
Consistent Ball Flights.

E9 and Dual Roll technologies are optimized for each driver loft, while CNC milling creates precise bulge and roll curvatures to improve driving accuracy and distance on off-center hits.

King F9 Ball Flight


Continually pushing the boundaries of innovation, Cobra engineers have created our largest carbon fiber crown design that is the first to wrap over the crown onto the body. This design produces a 12% larger carbon fiber area that saves 10 grams compared to titanium driver crowns.

F9 Carbon Crown Wrap

PWR Ridges

Engineered creases called PWR Ridges frame alignment and add rigidity to the carbon crown structure to create more energy return and power to the ball to maximize speed.

King F9 Bulge


Polymer crown trips are positioned relative to the direction of airflow around the club head to reduce drag and increase clubhead speed. Using a lightweight polymer material on the crown trips improves aerodynamics without raising the center of gravity. Titanium trips are positioned on the sole to speed up the flow of air traveling underneath the driver.

King F9 E9 Face Tech

Tune Your
Ball Flight.

The KING® F9 SPEEDBACK™ drivers feature adjustable center of gravity (CG) and MyFly loft technologies, allowing you to fine-tune trajectory and launch to maximize distance.

F9 Tune Your Ball Flight


Customize your center of gravity (CG) position using moveable weight technology. A heavy weight (14g) and lightweight (2g) can be moved to the front or back position to fine-tune trajectory, launch and spin.

Front and Back Positions

MyFly 8 with Smart Pad

8 easily adjustable loft settings allow players to manage launch and spin conditions to optimize distance. Smart Pad Technology keeps the face square at address regardless of the loft setting.

MyFly 8 with Smart Pad

Tour After Market Shafts.

Tour aftermarket shafts in varying weights and flex profiles are paired with each driver loft (9.0, 10.5, and 12.0) to complement the performance of the head. Actual aftermarket structures feature premium materials and stiffer, lower torque profiles that reduce spin for improved distance and dispersion.

Great driver
Review by Hh - 9/12/2019

I use to play taylormade but now it’s a f9 I’ll never go back

Review by Canada Steve - 9/7/2019

I play Cobra clubs, I love them, the look, the feel, the performance! I currently play the King F6+ Driver but gave the F9 Speedback a go at Golftown... All I could say was WOW!!! Right from the look at address to the amazing accuracy and extra 25 yards of distance!!! Can't wait to put this in my bag! Please make a special addition in Rickie's ORANGE!!!

F9 Speedback
Review by El Abogado Tomas - 8/16/2019

This is a great club. I try not to buy a driver every year. I have a feeling this one will be long term.

Living up to the Hype
Review by Drel - 8/2/2019

All the hype from this driver is legit. Got the driver on the 10.5 degree loft, set to 9.0. Avalanche head color. Hzrdous Smoke 70g shaft. Had it for almost a month now. The feel is great, it sounds powerful, it looks fast, super hot off the face and the performance is exceptional. I’m surprised on how many fairways I found. The miss hits are forgiving. Gained atleast 15-20 yards off the tee. Really happy about this driver, it’s going to sit in my bag for a long time.

Just keeps getting better.
Review by David - 7/13/2019

This club is the best Cobra driver yet. We've had the Fly-Z, the F8, and now the F9, this driver is an improvement over the previous clubs. Way to go!

Long & Straight
Review by Golflover - 6/21/2019

Haven’t previously used a Cobra driver before but the F9 is very impressive. Played the GBB Epic & Taylormade M2, the F9 is equally good if not better. Getting a consistent medium piercing trajectory with a lot of tumble on landing. Both length & accuracy is the best of all previous drivers I’ve played. In terms of performance & price, you can’t go wrong with the the F9.

Hitting Bombs
Review by Hoo-Day - 6/14/2019

Love this driver, 198 club head speed , just hitting absolute BOMBS!!!!

F9 Speedback Driver
Review by Wolvverine - 6/14/2019

Beautiful looking club. Has a more muted sound of the face compared to other drivers which I like. Long and straight with the hzrdus smoke

Sweet Driver!
Review by MarkyMark - 6/10/2019

Love the new Cobra f9 driver! Best new driver of the year! Maybe the sleeper of all the 2019 drivers! The best driver Cobra has ever made!! Easy on the eyes, and a real joy to swing and play with.

Great driver
Review by Jeff - 5/31/2019

Increased distance and accuracy...love my new Cobra driver, 3wd, and 5wd

Tour Length (TL) F9 Speedback Driver
Review by Kyle - 5/31/2019

Coming off a TM M6 Driver I felt comfortable with, I thought I would not be impressed when getting my fitting by Brandon out at Encinitas Ranch Golf Course in San Diego. I just have to say that the experience of the fitting and then the results are dramatic. Went into a shorter length which allows me to hit the sweet spot consistently and the sound and feel is unlike any driver I have ever owned. I can go after the ball with confidence and straight SEND IT!! M6 averaged 261 off the tee on trackman before switching to the TL F9 which was then averaging 288 on trackman. What a difference. And with cobra Connect to analyze all my shots, I have reduced my handicap with driver down to a single digit. Absolutely love this club and my Forged Tec irons. Thanks Cobra for a great product and your amazing fitter, Brandon Dickinson!!

Love this club
Review by Nate - 5/24/2019

I got this club after lots of research and because a tour pro helped me out. It comes of the face beautifully and feels great in the swing. You get good feedback on off center shots but the shot usually fly well unless I really do something wrong. First nice course I played I hit 11/14 fairways and the next course I hit 7/14, really poor boxes, But wasn’t the clubs fault. Super happy with this purchase.

F9 Speedback Driver
Review by Greg S. - 5/23/2019

Weather has not let me fully appreciate the driver, however with limited work it looks like a keeper. The custom fitting really feels good, Cobra increased the size of my grips and I like the feel and it has helped me with a lighter grip pressure. I don't feel like I have to grip so hard to keep the club in my hands.

Cobra F9 is amazing!
Review by The Vog - 5/3/2019

When I first saw this driver I liked the look. After some research on shafts I decided on an upgraded Oban Kiyoshi shaft to improve launch and bring down my spin rate. The F9 is the finest driver I have tried

Review by JR - 4/29/2019

Got the 9 degree F9 and put a Project X Red Stiff 75 shaft in it. Had to switch up the weights and moved setting to 10 degrees to achieve desired trajectory and maneuverability (was too flat and a baby draw was popping up here and there...yuck). But...once I got it set up right (also put 3g lead tape on toe) I added about 7mph and 10-15 yards from my TM M4, and more importantly was able to hit consistent hi launch baby fade I was after. Been dropping bombs since!

Best Driver Ever!
Review by Mad Golfer - 4/7/2019

Just played my first round with this driver, and all I have to say is WOW! I was dropping 290 yard bombs with zero carry. (Early in the season balls were plugging) I highly recommend the HZRDUS Smoke 60 shaft as well. This created a much lighter feeling driver, with a lot less whip in your hands than the other shafts offered.

I had purchased the 9 degree, and had it set to 9 with the red weight in the front. I was able to hit a few balls at the range with the weight in the back and it seemed to pull the heel on the club down. Having it in the front had a smoother follow through. Each hit was consistently straight (with the occasional draw) but I had much more control and feel as to what I was doing from my old drivers.

The cost compared to the other big name brands out there, this club wins in all categories hands down (having tried each of them before buying)
I got lots of compliments on the look (yellow) and the sound of each hit. It gives off a nice ping sound (no pun intended)

I’m a 60 yr old golfer and love my new F9 driver
Review by ACX - 3/29/2019

There are two reasons why I love my new driver. First this driver is extremely forgiving and I mean if you don’t catch the ball on the sweet spot the ball still flies down the middle. The second reason is when you catch it on the sweet spot the ball flies off the face and I’ve added at least 15+ yds. Overall one of the best golf purchase I’ve made in a long time.

Review by ABCJ - 3/16/2019

The service provided by Cobra Puma Golf was excellent. The F9 head is as advertised. I fully appreciated the choice of custom shafts. I am quite impressed and absolutely satisfied with this custom purchase.

Great Driver
Review by FowlPlay - 3/11/2019

All around solid driver. upgraded the shaft to the Tour AD Di 7 and love it

Review by Mark - 3/1/2019

Cobras Best driver yet!

Awesome driver!
Review by Svingit - 3/1/2019

Greetings from Sweden!

Got my custom King F9 with a 43.5" Hzrdus 6.0 shaft. Got 18 grams + 2 grams in the head. Ordered a 6 gram weight to replace the 2 gram weight.

It's a real low spin driver. carry it 272 yards and a total of 301 yards with a spin of 1660 rpm and a launch angle at 14-15 deg.

Speed back
Review by Asp Man - 2/18/2019

Awesome club waiting for some warm weather to get it out on course. Custom built lots of options and speedy service. Great experience.

New King of Speed
Review by Icemakr - 2/16/2019

Like others have said, best feeling and performing driver on the market. Picked up 5mph ball speed on center face contact and goes good even on off center strikes.

Toronto Star Golf Show
Review by CrazyCanuck - 2/9/2019

Yesterday, I was the first to try out two different F9 heads with different lofts. So excited about the feel, looks and sound I forgot to pay attention to the different loft and where the weights were located. Looking forward to a Demo Day somewhere in the GTA. BTW, the representative was very helpful and spent some precious time with me while setting up his area. Thank you.

Worth it
Review by Steve - 2/4/2019

Absolute game changer of a driver! Best feeling and sounding club out there! Never thought I’d switch out my M3 anytime soon, but i hit this once and never looked back!!

New F9 Speedback
Review by Al - 1/25/2019

Very Helpful! I am a 12 handicap and interested in the shaft options for the Regular flex in the New F9 Speedback...looks like I will consider at Demo the UST Helium 50 and Atmos Tour Spec Blue 6!
