KING F9 SPEEDBACK Special Edition 4 Iron

When Rickie Fowler first put this iron in play at The Shriners, it proved to be a sneaky weapon. Now, we are offering a limited quantity of these F9 SPEEDBACK 4-irons, designed after Rickie’s specs. We can’t guarantee you’ll crush it 290 off the tee like Rickie, but if speed, high launch, and distance is what you’re looking for, there’s a spot for this one-of-a-kind driving iron in your bag.

Rickie 4 Iron
KING F9 Irons
  • What IS IT

    This Special Edition KING F9 SPEEDBACK™ 4-iron is equipped with a Graphite Design Tour AD IZ shaft and a Lamkin Crossline COBRA CONNECT™ grip, the perfect combination for driving off the tee or 2nd shots on a par 5.

  • WHO IT'S FOR

    If it is fast and long enough for Rickie to use off the tee, it is sure to be a great set up for you. On tee shots into narrow fairways that call for long and controlled ball flights, the KING F9 driving iron will not disappoint.

  • Why we made it

    Why should only Tour Players get all of the special treatment? This KING F9 SPEEDBACK™ 4-iron is specially made for Rickie, and validated on Tour, so we wanted to offer you the same configuration he plays at an excellent value.

King F9 Rickie 4 Iron

SPEEDBACK DESIGN

Much like a wide-body kit adds to the stability of a racecar, SPEEDBACK shaping utilizes a belt of steel that adds mass low and wide, creating a lower, deeper CG that maximizes ball speed, launch and carry while maintaining a conventional sole width.

CNC Milled face driver

FORGED E9 PWRSHELL FACE

An E9 variable thickeness face design is 1.8mm at its thinnest point, expanding the SWEET ZONE to increase distance on off-center hits. A forged PWRSHELL design features a deep undercut sole with a 1.2mm internal Speed Channel that returns more energy to the ball for higher launch and faster ball speeds.

King F9 Bulge

HIGH MOI DESIGN WITH TUNGSTEN

SPEEDBACK adds more mass low and wide compared to a conventional game improvement iron. 33 grams of tungsten is combined in the heel and toe in the 4-7 iron, increasing MOI for maximum stability, higher inertia, and substantial improvements in ball speed, distance and forgiveness.
