King F9 Speedback ONE Length Irons

Powerful, Stable, and Accurate

Speedback Technology

Revolutionary Speedback™ Technology combines innovative shaping elements and heel and toe Tungsten weighting to achieve the ultimate combination of low CG and high MOI, delivering maximum power and stability.

Co-Molded Medallion

3-piece multi-material medallion design featuring aluminum, TPU and acrylic foam dampens vibrations to promote a softer, more responsive feel.

Forged E9 PWRSHELL™ Face Technology

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

CNC Milled Face and Grooves

CNC milling delivers more precise face and groove structures for improved spin and trajectory performance.

Cobra Connect

Cobra Connect, powered by Arccos™, features electronically enabled grip s that work in conjunction with the Arccos Caddie app, allowing users to track their stats and improve their game.

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 CG and add bounce, making it easier to get the ball airborne from any lie and turf condition.

Progressive Shaft Weighting

Three 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.


Standard Steel Shaft: KBS Tour 80 (4-6 Iron), KBS Tour 90 (7-9 Irons), KBS Wedge (PW-SW)
