Cobra is not widely known to be a leader when it comes to groundbreaking technology. They have been looked at as the alternative, the other option if you don’t go with Ping, Callaway or TaylorMade.

In the last few years, Cobra has changed that. The F9 released in 2019 was a reliable option that people saw significant improvements with. Not to mention the one length concept that was introduced a few years ago.

In this Cobra King Speedzone Irons review, will talk about Cobra SZ Irons, released in January 2020. These are cavity back irons built for the mid to high handicapper.

The Speedzone is available in the one length option as well, just as the Cobra F9 is. If you are looking for an incredible game improvement iron at a fair to reasonable price, the Speedzone is undoubtedly worth considering.

Features and Benefits

The Speedzone irons are all about speed. Cobra focused on four different areas to help increase ball speed in this set.

  • Light Zone- Carbon Fiber Topline
  • Power Zone- Forged PWRShell Face
  • Stability Zone- Speedback Shaping
  • Feel Zone- Co Mold Medallion

Player Handicap

This is a game improvement iron. If you lack ball speed and distance, this is the club for you.

Lower handicap players looking for feel and feedback will not find that with these irons and should consider that when looking at the Cobra King Speedzone irons.

Shaft Options

As with all newly released irons, you can order the Cobra King Speedzone irons in just about any graphite or steel shaft option that you might like.

The stock steel option is a standard one from Cobra, the KBS Tour 90 Steel. This KBS Shaft is designed for players looking for high launch and speed.

The Graphite stock shaft is the UST Recoil 460 ESX. If you are looking for a lighter option and increased speed, the Graphite option is the way to go. Loss of feel and control can happen when switching to graphite. Every review on this shaft does mention increased feel and control.


These irons are thick. If you like a thin-looking iron, the Cobra King Speedzone is not for you. The reasoning behind the thickness is increased stability, higher launch, and some more natural shots out of difficult lies.

A common complaint among cavity back irons, especially ones of this size, is the sound at impact. Manufacturers have done a lot in the last few years to make your hands sting just a little less on that off-center hit.

Cobras’ version of that is called the co mold medallion. The Co Mold Medallion is a small insert featuring aluminum and acrylic foam to help absorb some of the impact and make these feel and sound better.

It does work, but you cannot expect the cobra king speedzone irons to feel like a forged club.


Without making this too complicated, the Cobra King Speedzone iron is the longest iron that Cobra has ever released. Their new PWRShell face helps to increase distance by offering a 35 percent larger sweet spot.

Even when you miss the center on these, you will not see shots landing twenty yards behind.

As we all know, distance is directly related to ball speed and clubhead speed. With these irons, Cobra installed the first-ever carbon fiber topline. This is not just brand new technology for cobra irons but also irons in general.

The carbon fiber saved three grams and led to the Cobra King Speedzone irons having a much lower center of gravity. Every review of these Speedzone irons has them competing with TaylorMade SIM MAX and Callaway Mavrik to the highest level.

Not directly distance-related, but another impressive benefit of the Cobra king Speedzone irons is the Cobra Connect Technology. Cobra released this concept several years ago with the F7 and F8 lines.

A sensor in the grip of your Speedzone irons will track each shot and provide data in the Cobra Connect app on your phone or mobile. For players looking to improve their golf game, the Cobra Connect technology can be a great way to identify your weaknesses in your game.

Our favorite part about the iron app is what Cobra King calls the Arccos Caddie AI. By continually tracking your distance data, you will get an accurate idea of how far you hit each club.

Many mid to high handicap players are guessing about the exact distance that they hit their irons. Cobra King took that away with this technology-enhanced irons set.


In addition to the PWRShell face offering a 35 % larger sweet spot, Cobra also introduced what they call Stability Zone technology.

Simply stated, they worked on the shape of the clubhead to make sure the Cobra King Speedzone irons are much more stable at impact on off-center hits.

This concept is carried over into the Cobra King Speedzone One Length irons as well.

If you are seeking pure forgiveness and consistency in your game, take a look at the One Length Irons Cobra manufacturers as they will make stance and set up the same for every iron shot.

As far as forgiveness is concerned in a set of irons, these have all you could need and more. For a lower handicap player looking for lots of feedback and workability in a set of irons, the Speedzone Irons are not going to be the number one choice.


One of my favorite things about Cobra is that they release a set of irons at a fair price and then continue to drop it as the season goes on.

These Cobra King Speedzone were released at an average game improvement price for a 4-PW in the steel shaft. A very fair value for the technology and innovation you will receive.

TaylorMade SIM MAX

The SIM MAX Irons by TaylorMade is an excellent alternative to the King Speedzone. The price point is going to be similar, although slightly more expensive.

TaylorMade has been producing irons that have higher ball speeds than almost any other iron on the market for several years.

The SIM MAX irons come in an oversized version that will give even more forgiveness to the players that need it most. The oversized version is a larger, thicker clubhead with a broader sole, but it is quite useful in increasing launch.

The main goal for TaylorMade was to create something that feels as close to a forged iron while offering the maximum amount of forgiveness and distance.

They did create an iron with a slightly better look and feel than the TaylorMade M6 irons released in 2019, although the SIM MAX is very similar to the M6.

Callaway Mavrik

Right off the bat, the advantage to the Callaway Iron is going to be the variety of options offered. If the Mavrik is not the perfect fit for you, you have the Mavrik Pro and the Mavrix Max to choose from.

Cobra doesn’t provide this with the Speedzone except for the One Length option.

The Mavrik is going to have a thinner look to them, and without the carbon fiber topline that Cobra King Speedzone has implemented, they will be slightly more substantial.

The look and feel to this iron is still going to be a game improvement very similar to the Cobra King Speedzone. Overall the Mavrik is going to appear quite a bit less clunky than the Cobra King Speedzone as well.

As we mentioned earlier, although the Speedzone irons are improved from the F9 Speedback, they are still quite thick and substantial.

Cobra iron sales have skyrocketed over the last several years. Working on shaft weighting, club head materials and shapes, and the technology side of the game, they have put themselves into the game.

The Cobra King Speedzone irons are going to be a bestseller this year. If you have not upgraded your irons in several years and are seeking something that gives you easy distance and launch the Speedzone irons are something that you need to consider.

Hopefully, this Cobra Speedzone irons review left you feeling like you have enough information to decide if the Speedzone is a good fit for your game.
