Cobra King F9 SpeedBack Combo Iron Set

Revolutionary SPEEDBACK™ Technology combines tungsten weighting and innovative shaping to deliver the most powerful and stable COBRA iron. SPEEDBACK™ Technology combines a low, back weight with a faster, re-engineered BAFFLER® rail design to lower the CG and improve speed, stability and launch from every lie.
IRONS
SPEEDBACK - 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.
CO-MOLDED MEDALLION - A 3-piece multi-material medallion design featuring aluminum, TPU and acrylic foam damps 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 & GROOVES - CNC milling delivers more precise face and groove structures for improved spin and trajectory performance.
PROGRESSIVE HOSEL LENGTHS - Shorter hosels in the 5-6 irons lower the CG for increased launch and distance, and taller hosels in the wedges raise the CG for lower, more controlled trajectories.
HYBRIDS
SPEEDBACK - Re-engineered BAFFLER® rails and a low, back tungsten weight optimize turf interaction and lower the CG for improved launch and faster clubhead speed from any lie.
FORGED 455 STAINLESS STEEL FACE - A thin, forged high-strength stainless steel insert maximizes flex for increased ball speeds and launch across the face.
HIGH MOI SHAPE - A 10% larger clubhead increases MOI, while a lower toe and a square leading edge combine to promote a lower CG and improved alignment for increased accuracy and precision.
BACK CG POSITION - A fixed, interchangeable weight positioned low and back promotes high, towering ball flights and maximum forgiveness.
