Studying vibrational analysis, COBRA® engineers discovered the use of carbon fiber combined with an improved clubhead construction damps vibrations resulting in a softer, yet more solid feel.
COBRA's patented TECFLO™ Progressive Set Technology utilizes different clubhead constructions that deliver perfected trajectory and feel from the long irons to wedges.
Variable hosel lengths promote optimized launch, speed and forgiveness through the set. Lower profile long irons with shorter hosels lower the CG for increased launch and forgiveness. Progressively taller hosels in the mid to scoring irons raise CG for improved control and accuracy on approach shots.
CNC milling delivers more precise groove structures resulting in optimal spin and trajectory characteristics for the long irons, mid to scoring irons and wedges.
The KING® F8 ONE Length™ irons feature cutting-edge technologies that make them even easier to hit and more consistent than ever before.
Evolving the performance of ONE Length™ irons required extensive research and testing. Utilizing unique constructions and technologies, COBRA® has taken the performance of KING® F8 ONE Length™ irons to the next level.
Featuring a lower profile clubhead design with wider soles in the 4-6 irons, the CG is moved lower and deeper to deliver higher launching trajectories. Paired with an optimized E9™ Sweet Zone™, the KING® F8 ONE Length™ long irons are faster and longer, while maintaining the simplicity and accuracy that players find appealing with the ONE Length™ set makeup.
The key to a better short game is knowing your wedge distances. The KING® F8 ONE Length™ wedges give you more confidence with one setup and one swing, while an improved clubhead construction promotes lower, more controlled trajectories. The result is more consistency, more predictable distances, and closer birdie opportunities.
COBRA® has teamed up with its shaft partners to engineer unique designs that optimize ONE Length™ performance. Utilizing flighted shaft technologies, the graphite and steel shafts feature adjusted flex profiles that make the long irons play softer and launch higher, and the short irons play stiffer and launch lower.
The industry's first ever ONE Length™ hybrid is engineered to match 7-iron length, weighting, and lie angle. Its low CG design produces higher launching trajectories and faster ball speeds, making it the perfect complement to the KING® F8 ONE Length™ irons in a combo set.
