KING F9 Driver
  • What Is It

    The KING F9 SPEEDBACK™ Junior Driver is designed to equip Juniors with the performance they need to achieve their best potential. Designed with a shorter and softer shaft, a lighter swing weight and a higher loft range to provide maximum speed, distance, and forgiveness for young golfers.

  • WHO IT'S FOR

    Designed for beginner to advanced Junior golfers ages 8 to 14 with moderate to faster swing speeds.

  • Why we made it

    SPEEDBACK™ Technology delivers the ultimate combination of speed, distance, and forgiveness for Junior golfers. A lighter weight configuration paired with adjustable CG and MyFly loft technologies allows Juniors to fine-tune their launch and spin conditions as they develop their game.

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

UP TO 5 TIMES
MORE PRECISE

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

INDUSTRY LEADING
TECHNOLOGY

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.

OUR THINNEST
& HOTTEST FACE

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

Speed Tuned
Performance.

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.

2. 7-DEGREE AXIS TILT

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

3. BOTTOM ROLL CURVATURE

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

PERFECTED BULGE

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.

COBRA'S FIRST EVER
CARBON WRAP CROWN

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

360 AERO TECHNOLOGY

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

ADJUSTABLE CG

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.

The new KING F9 SPEEDBACK™ Junior Driver is fueled with the same technologies as the men’s SPEEDBACK™ Driver, only with a shorter shaft length, lighter swing weight, and higher lofts ideal for the Junior golfer.

The Junior Driver is equipped with 2 (Front & Back) Center of Gravity settings. Position the 10g weight in the back position to promote higher launch, or position it in the front to promote lower launch with reduced spin.

The MyFly8 adjustable loft technology allows junior golfers to fine-tune their launch and spin conditions as their game develops, helping them manage their distance and trajectory. Eight easily adjustable lofts range from 11° - 14° (STD loft = 12.5°) including three draw settings: 11.5°, 12.5°, 13.5°.

The KING F9 SPEEDBACK™ Junior Driver then takes adjustability a step further with Smart Pad®, COBRA’s proprietary sole technology that maintains a square face at address regardless of the loft setting. This helps the junior golfer to align the club with a square face at address.

    I bought this for my my son (just 11 years old). He was hitting his US Kids driver pretty far but with this new gear he get additional distance and consistency.

    Great driver

    Review by Jake - 8/17/2019

    My 12 year old gained 30-40 yards switching from USKids tour series to the Cobra F9. He is driving 225 now and can move back to the men’s tees. He loves the built in tracker as well. With the free shaft exchange, he will be playing this driver for at least 3-4 years.

    good driver, could use more shaft length options

    Review by Chris - 7/23/2019

    I bought this driver for my daughter who is upgrading from her USKIDS TS3 driver and set. I started with the shortest shaft available but it is still significantly longer than the shaft my daughter who is 43" tall can use without having to choke up somewhat. She is currently 10 years old. An additional shaft length slightly shorter in the 36" range would be helpful. Because of this we have had to put this driver back on the shelf for awhile.

    awesome driver

    My child has the Cobra Junior complete set. The driver in that set is good, but this driver is constantly 10+ yards longer. Great club for Junior golfers.
