KING F8 Junior Driver

The KING F8 Junior Driver introduces COBRA's first CNC milled driver face paired with 360° Aero™ Technology, bringing you COBRA’s smartest, fastest, most precise driver ever. Comes with a free shaft upgrade as Juniors grow into their game.

  • What It Is

    Featuring COBRA's thinnest and hottest face, the KING® F8 Junior driver delivers the perfect blend of speed and forgiveness with precision face milling, aero and adjustable weight technology. Engineered with varying swing weights and shaft lengths depending on player height, Juniors will also receive a free shaft upgrade as they grow into their game.

  • Who It's For

    Beginner to advanced Junior golfers of ages 8 to 14 with moderate swing speeds. Its oversized shape makes it ideal for those seeking a more forgiving profile and improved distance on mis-hits.

  • Why we made it

    Featuring the same innovative technologies as the KING F8 Men’s driver, the KING F8 Junior Driver is designed with a higher loft range and a lighter head weight to help promote more launch and speed for Junior golfers. Moveable weights and MyFly8 Technology allows juniors to manage distance and trajectory as their game develops.

Introducing the First
CNC Precision Milled Face

Golf's first CNC precision milled forged titanium driver face with E9 Technology™ is thinner, hotter, and more precise.

CNC Milled

Precision Milled For Maximum Speed

CNC milling yields more precise face thickness controls compared to hand-polishing, allowing COBRA engineers to design a thinner and faster conforming face.

COBRA's Thinnest and Lightest Face

Tighter face thickness tolerances allow the face to be milled as thin as possible to deliver increased deflection for faster ball speeds. This yields a face that is 10% lighter.

Multi Directional CNC Milling Pattern

A multi-directional CNC pattern delivers a thinner face, while the circular milling pattern in the center provides an aesthetically pleasing visual of the Sweet Zone™.

CNC Milled
Vs. Hand Polished

The traditional hand-polishing process can lead to inconsistencies in face thickness and curvature between each manufactured driver head. CNC precision milling ensures that every driver face is machined to precise specifications to achieve optimal performance.

Compared to hand-polished drivers, CNC machining yields more precise thicknesses resulting in a thinner and hotter face that increases ball speed and distance.

Precision Face

Ti-8-1-1 Body & Forged E9TM Face

A lightweight 8-1-1 Titanium body and forged face saves discretionary weight to move the CG lower for improved launch and speed. CNC milling delivers a thinner and more precise E9™ variable thickness face structure for increased distance on off-center hits.

Lightweight Body

Ball Speed Gains

Tested against a traditional hand-polished driver face, the CNC milled face on the KING® F8 driver produced increased ball speeds ranging from 1.2 to 1.6 mph across the face.

Ball Speed Gains


After analyzing over 25,000 unique shots in our testing, we discovered that 99% of golfers hit the face in an elliptical pattern ranging from low heel to high toe. While most golf companies design a circular sweet spot around the center of the face, COBRA's patented E9 Technology™ is designed in an elliptical pattern to create a SWEET ZONE™ that allows more hot spots farther away from the center of the face.

Unlike traditional drivers designed with a constant roll radius, COBRA's innovative Dual Roll Technology™ utilizes different curvatures on the top and bottom of the face to optimize launch and spin for shots hit above or below face center.

Dual Roll

tilted bulge and roll axis

COBRA's patented Dual Roll™ design features more curvature on the top half of the face and a flatter bottom half to optimize launch and spin for shots hit both high and low on the face.


perfect bulge

Using CNC milling, COBRA® engineers were able to design a more precise horizontal face curvature (bulge radius) to compensate for gear effect and deliver more accuracy on shots hit on the heel and toe.

Perfect Bulge

360 AEROtm

Innovative crown and sole aero trips optimize aerodynamic performance for faster clubhead speeds and increased distance.

Next Level Speed


Polymer crown trips are 10% lighter than Titanium, to help improve aerodynamic performance without raising the CG. Titanium trips are utilized on the sole for increased durability, while lowering the CG for enhanced speed.

360 Aero Technology

less drag more yards

Represented in the CFD (Computational Fluid Dynamics) models below, the streamlined shape of the KING® F8 driver optimizes the flow separation on the crown and sole to significantly reduce drag. Lower drag will give you more clubhead speed and ultimately more distance off the tee.

Less Drag


Distance is dependant on club speed. The addition of aero trips and a more streamlined shape is important to reduce drag in areas of the swing where speed is lost. The aero trips are strategically positioned relative to the orientation of the airflow, speed, and drag through the swing to increase clubhead speed for maximum distance.

Rickie Swing

Two adjustable cg settings:
back & heel

The KING® F8 driver features back and heel CG settings, allowing you to tune your trajectory and spin to maximize distance.

Adjustable Settings

tune ball flight

The back weight setting promotes higher, towering ball flight, while the heel weight setting promotes a slightly lower launch with increased draw bias.

Tune Ball Flight

myfly 8 with Smart pad

8 easily adjustable loft settings help you manage trajectory and fine tune launch and spin to maximize distance. Increasing or decreasing the loft will adjust the launch by +/- .5 degrees and the spin by +/- 400 rpms, respectively.

Myfly Eight

Oversized profile

A larger clubhead profile at address paired with two very forgiving (back and heel) weight settings, increases MOI for more distance and speed on off-center hits.

Oversized Profile

Ultralight Carbon Fiber Crown

Lightweight carbon fiber provides the weight savings needed to incorporate moveable weights into the design, while also repositioning weight low and back for improved launch and forgiveness.

The new KING F8 Junior Driver is engineered to deliver the same blend of maximum distance and increased forgiveness as the men’s KING F8 Driver, with shorter shaft length options and higher lofts ideal for the Junior golfer.

The Junior Driver is equipped with 2 (Back & Heel) Center of Gravity settings. Place the 12g silver heavy weight in the back position to promote a higher, towering ball flight with more carry, or place the weight in the heel position to promote a medium to high ball flight with draw bias.

The MyFly8 adjustable loft technology allows junior golfers to tune their launch and spin as their game develops, helping them manage their distance and trajectory. The Junior Driver can be adjusted to the following loft settings: 11° - 14° (std loft = 12.5°) and three draw settings: 11.5°, 12.5°, 13.5°.

The KING F8 Junior Driver then takes adjustability a step further with SmartPad, COBRA’s proprietary technology, which delivers a square face at address regardless of loft setting. This helps the junior golfer to align the ball straighter down the fairway at address.


Since kids grow very quickly, we are continuing the Free Shaft Upgrade option with the KING F8 Junior Driver. Golfers can register their purchased F8 Junior Driver, email the registration info to and receive one free upgrade to a longer, firmer shaft when needed.
