Have a Question? Ask a PGA Professional


The Cobra King F8 One Length irons are Cobra’s first ever connected set of one length irons that will help you to improve your game by tracking your performance with the Cobra Connect Powered by Arccos. The One Length irons have been re-engineered to match 7-iron weighting and length to deliver more consistent trajectory and distance gapping throughout the set. Forged VFT PWRSHELL Face Technology enhances the Sweet Zone for faster ball speeds and higher launch across all points on the face while the CG is lower for higher launch and more clubhead speed. For the first time ever in an iron, a lightweight carbon fiber medallion supports a thinner face while delivering improved sound and feel. Tailored performance throughout the set is delivered by TECFLO Progressive Set technology and Progressive Spin Technology uses V-Grooves on the 4-6 iron to reduce spin, U-Grooves on the 7-PW optimize spin and wedge-spaced grooves on the GW-SW deliver extra spin for shots around the green.

Does it come with additional sensor? Like for wood, wedges and putter.
asked by Joselito V. on 12/8/2017
New sets will come with the additional sensors as stated on Cobra's website. Used ones will not.

can you speak to the difference between the True Temper One Flighted Steel and True Temper XP 90 Steel shafts?
asked by Marc M. on 2/6/2019
They are actually the exact same shaft. Both names are listed on the shaft.

Technology / Specs

The Cobra KING F8 One Length irons are the industry's first connected set of irons. These irons have the same technology as the KING F8 irons with one major difference; each iron is the same length. Read on to find out more.

One Length Construction

The Cobra KING F8 One Length irons are built to 7-iron length. The means the setup and swing don't need to be changed with each iron, simplifying the game. A new flighted graphite and steel shaft in the KING F8 One Length irons adjusts the flight based on the loft. The 5-7 irons have higher launch and spin for distance. The 8-GW have lower launch, making them more accurate.

Cobra Connect

For the first time in an irons set, Cobra adds its popular Cobra Connect powered by Arccos data tracking system. Each iron has a sensor that will give you GPS locations during your round, track distances and accuracy, all through the free Arccos app. You can use this information to get to know your game better and how to improve.

TECFLO Technology

TECFLO technology, first seen in the KING F7 irons, is a progressive head design that optimizes performance for every iron.

Long irons (4-7 irons) are fully hollow, offering high launch and the most forgiveness in the set. The middle irons (8-PW) are a cavity back design for more accurate shots as you approach the green. The wedges (GW-LW) have an almost blade-like design for precise shots around the green.

Optimized CG location

The KING F8 One Length irons also have a progressive CG location. The CG locations of the long irons (4-7) are low, in the middle for 8-PW, and higher in the wedges. The main way Cobra does this by having different length hosels. Longer hosels raise the CG location.

Progressive Spin Technology

The grinds are also designed differently to give each iron the perfect amount of spin. The grooves on the long irons (4-7) are v-shaped. The middle irons (8-PW) have u-shaped grooves. The grooves on the wedges are shallower and tighter together for more spin.

Other Features

The PWRSHELL face on the King F8 One Length irons is thinner and lighter than previous versions. The PWRSHELL face flexes more at impact for higher ball speed and distance.

a carbon fiber backing and lower profile design give these irons tremendous look and feel.
