King F9 Speedback One Length

The KING® F9 ONE Length™ irons are engineered to simplify your game by reducing variability in your swing to increase confidence and consistency.


A combination of a low, back weight feature and heel and toe tungsten creates the best combination of low CG and high MOI, delivering extreme power and stability.

One Length™ Configuration

Engineered using matching 7-iron length and swing weight specifications, a ONE Length configuration simplifies your game by reducing the variability in your swing for increased confidence and consistency.

Wider, Hybrid-Like Sole

Wider soles in the 4-6 irons lower the club's center of gravity and add bounce, making it easier to get the ball airborne out of any lie and turf condition.

Progressive Shaft Weighting

3 different KBS shaft weights (KBS Tour 80, 90 and Wedge) in the set promote the desired launch, feel and trajectory for the long irons, mid irons and wedges.

Forged E9 PWRSHELL™ Face Technology

An E9™ variable thickness face design and PWRSHELL™ Technology expands the SWEET ZONE™ for higher launch and faster ball speeds across a larger area on the face.

Got these clubs over a week ago played about 6 rounds with them so far i have had more
birdies in the past 6 rounds than i did all of last year. The only club im stuggling to hit
is the 5 iron but im sure its not the club. The 6, 7, 8 and up im getting 10 to 15 yards
more than my old Taylor Made RBZ and more consistency. I'm currently an 18
handicap looking forward to seeing how much lower i can drop this year with these
new clubs.
Prosgreat price
Conswish the set came with a Sandwedge will have to order it separately also can't order clubs with Mid or Oversize grips

I currently have a set of Cobra F7 one length irons and love the one length concept. I would love a set of F9 Speedback one length irons. In return i will play and supply real world review feedback and weekly score cards to track my improvement using the F9's.
