Cobra King F9 SpeedBack Irons (Graphite Shaft)

THE ULTIMATE FORMULA FOR SPEED

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 intertia 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.

Revolutionary SPEEDBACK™ Technology combines tungsten weighting and innovative shaping to deliver the most powerful and stable COBRA iron.
