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.
