Product Details

The COBRA KING F9 SpeedBack Irons feature a bold, innovative design that delivers the most powerful and stable COBRA iron to date.


With bold shaping and revolutionary SpeedBack technology the COBRA KING F9 provides the ultimate combination of low CG location and high MOI making it ideal for the golfer looking for maximum distance and forgiveness without sacrificing control.

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.

LOW CG SPEEDBACK SOLE - Additional mass is added low and back, delivering a lower and deeper CG that increases ball speed and launch to maximize distance. The mass is strategically elevated from the contact area of the sole to maintain a sleeker appearance.

HIGH MOI DESIGN -
A higher MOI is achieved using a combined 33g of Tungsten in the heel and toe, increasing stability and inertia for the best combination of distance and forgiveness. Using innovative shaping elements, the SPEEDBACK™ weight features are disguised in a streamlined shape at address.

FORGED E9 PWRSHELL FACE -
An E9™ variable thickness face design is 1.8mm at its thinnest point, and expands the SWEET ZONE™ area on the face. A forged PWRSHELL™ design features a deep undercut sole with a 1.2mm internal channel that absorbs and returns more energy to the ball for higher launch and faster ball speeds.

CO-MOLDED MEDALLION - A 3-piece multi-material medallion in the 4-7 iron combines Aluminum, TPU (Thermoplastic Polyurethane) and Acrylic foam. The combination of lightweight, vibration damping materials promotes a softer, more responsive feel that is not normally found in a game improvement iron.

CNC MILLED FACE & GROOVES - Utilizing a precise manufacturing process typically found only in forged players irons, the KING F9 irons are the only game improvement irons to feature CNC milled faces. CNC milling delivers a perfectly flat face, precise grooves, and precise lofts for maximum spin and trajectory control.

PROGRESSIVE SPIN TECH - CNC milled V-grooves in the 4-7 irons reduce spin for increased distance and flight time, U-grooves in th 8-PW optimize spin for improved control and accuracy, and tighter-spaced wedge grooves in the GW and SW increase spin for more greenside precision.

To make the ONE LENGTH concept work properly and create the right ball flight and gapping COBRA have fitted a mixture of shafts in the set (KBS Tour 80 (4-6 Irons), KBS Tour 90 (7-9 Irons) & KBS Wedge (PW, SW)). A premium Lamkin Crossline Connect has been fitted as standard.
