USGA CONFORMING
VS
NON-CONFORMING

  • Understanding the difference between USGA Conforming and Non-USGA Conforming is important. The reason this driver in Non-USGA Conforming is because the spring effect of the face of the driver far exceeds what the USGA allows for tournament play.
  • If your swing speed is no more that 110 MPH, want to absolutely maximize distance off the tee box and don't care if the driver you hit conforms to USGA rules for spring effect, this driver is for YOU.
  • The simple truth is many golfers, especially older golfers just want to enjoy the game more. Adding an extra 20+ yards down the fairway really is a big deal when your swing speed is 60, 70, 80, 90 MPH.

THE NEW 2020
FORMULA DOUBLE X EXTREME
USGA NON-CONFORMING DRIVER


The Formula Double X Extreme Driver is made for speed and is the longest hitting driver in the world. 

100% HANDMADE


The Formula DOUBLE X EXTREME Krank Golf driver is 100% Handmade with the highest quality craftsmanship and materials on the planet.

SUPER-HOT FORGED BETA TITANIUM FACE


(Pure Titanium /Grade.4) From triple plasma welding, the latest super hardened Beta Titanium, to added sole plate louver placement for maximum energy transfer back to the golf ball. We push every possible advantage to gain performance. We do not build cast drivers. We only build 100% Cupped Faced Forged Drivers. There is no comparison in performance or durability.

FUJIKURA SPEEDER X TOUR SHAFTS


Built with extremely fast high modulus graphite to generate additional swing speed.

HIGH (COR) COEFFICIENT OF RESTITUTION DESIGN


COR is the measurement of how a ball, slingshots off the face of a driver. The conforming COR limit of the USGA is .830. We have increased the Formula Double X Extreme COR to .890. The result is increased ball speed, decreased spin and of course, longer drives.

MAXIMUM ENERGY TRANSFER (MET) TECHNOLOGY


Every golf driver we make includes our exclusive Maximum Energy Transfer (MET) Technology, which simply means our golf drivers store and releases energy back to the ball better than any golf driver in the world. Golf driver performance is far more than just how the face performs. The rigidity of the body of the driver plays a significant role is ball speed, spin control, directional control, and energy storage.

AIR-FLOW STABILIZER DESIGN


Directing airflow over the crown for increased stability on swing path and increases club head speed.

Additional body rigidity in the crown of the driver head to minimize body deformation at impact. Storing energy forward in the head and releasing that energy back to the ball more quickly is critical for increased ball speeds.

HEEL AND TOE LOUVERS


Body rigidity is one of the most important performance features in all Krank Golf drivers. The heel and toe louvers create substantial strength in those areas which assist in straighter hitting on off center strikes.

TRI-SLEEVE ADAPTER


The FORMULA DOUBLE X EXTREME drivers are the only Cupped Faced Forged adjustable drivers in the world. The Tri-Sleeve Adapter allows for maximum adjustment without turning the shaft in the driver. For those golfers who spine or pure their shafts, this is a big advantage to other adapters which require turning the shaft to adjust loft.

HIGHEST BALL SPEEDS
HIGHEST TRAMPOLINE EFFECT
7-8% Higher Ball Speed = 10-12% Distance Gain!
LONGER DISTANCE
20-40 Yards in Increased Driving Distance.
MORE ACCURACY

The Formula Double X Extreme Driver creates a lighter, more flexible face. The 100% Cupped Faced Forged design increases the size of the sweet spot, leading to greater forgiveness, and increasing the ball speed immediately after impact.

MORE DURABILITY

The Formula Double X titanium driver faces are over 4 times harder than cast driver faces. Allowing us to micro CNC mill the face thinner for faster ball speeds, better spin control and anti-face flatting durability.
