Cobra Speedzone Vs Cobra Aerojet Irons Comparison Overview

When the Speedzone irons came out, Cobra claimed that they had a revolutionary design.

It’s 2023 and the new Cobra Aerojet iron are being dubbed the most technologically advanced irons produced by the company.

We wanted to go beyond all the marketing and get to the bottom line: the performance. So we tested the new Cobra Aerojet irons against the established Speedzone irons to see what each set brings to the table.

Cobra Speedzone Irons Overview


“By far, the most remarkable feature of the Speedzone irons is the carbon fiber topline.”

It’s the most remarkable feature because it’s the one you will see the most if you actually own these irons. The carbon fiber topline is meant to reduce weight so the CG can be placed lower in the head. But at address, it has sort of a checkerboard look that can be a bit distracting.

Nevertheless, the Cobra Speedzone irons impressed us mainly because of the progressive hosel length design. The hosels are a bit longer in the longer irons and they shrink down as you work down the set. This affords the player good distance in the long irons and better control and workability in the short irons.

The PWRSHELL face insert is essentially a variable thickness face insert. It helps to preserve ball speed on strikes made away from the sweet spot. Overall the Speedzone irons produce good distance and greenside control.

Cobra Aerojet Irons Overview

“The Cobra Aerojet irons have a forged PWRSHELL insert that produces a softer feel.”

The idea with the face insert is the same: generate more forgiveness by thinning out the areas where players usually mis-hit. The Cobra Aerojets are cavity back irons with a very low launch. Our testers really liked the low, piercing trajectory and low spin rates they were getting from these irons.

In terms of distance, the Cobra Aerojet irons outperformed the Speedzone irons by an average of 5.6 yards. The feel has been softened up a bit too which is nice for short approaches. To keep the CG low, the Cobra Aerojet irons have a new suspended weight in the back of the head.

“The Cobra Speedzone irons are better all-around irons as they allow for better workability in the short irons while still producing considerable distance. The Cobra Aerojet irons are the better distance irons as they simply play longer.”

Cobra Speedzone First Impressions


When you first pick these irons up, it feels like that are too light to deliver the kind of distance that beginners with slower swing speeds need.

However, after you play around with them, you’ll realize that they do in fact produce good ball speed – even if you have a slower swing speed. The deep undercut allows the face to flex to a high degree; unleashing fast ball speed even fore beginner players.

We tested these irons in graphite shafts but you can also get them with KBS Tour 90 steel shafts. The graphite irons added to the distance and overall feel of these irons. They helped keep the weight down and contributed to flex.

There are also rear badges on these irons that are made form a combination of aluminum, acrylic foam and thermoplastic polyurethane. So even on full-bore swings, these irons maintain a nice, smooth feel.

The Cobra Speedzone irons don’t look or feel like much at first; but they really shine in terms of distance and forgiveness.

Cobra Aerojet Irons – First Impressions

“Right away, we liked the moderate footprint of these irons.”

We could just tell by looking at them out of the packaging that they would suit the needs of a wide variety of everyday golfers. They look forgiving, are forgiving and will provide you the launch angles you need for any kind of lie. Around the pin, you can unleash their full launch potential to nail fast greens. And from distance, the naturally low launch will give you piercing trajectory and ball speed.

The Cobra Iron Family

“The T-rail irons are also a handy choice for high handicappers.”

Who are the Cobra Speedzone Irons for


The Cobra Speedzone irons would definitely be more suited to high handicap players.

Don’t get the wrong idea of these irons; they will not offer a lot of value to low handicap players. They don’t have the dynamic spin control that low handicappers value. They also don’t offer very much in the way of shot shaping ability.

However, none of that really matters if you are a high handicapper who is really just starting to get the hang of your irons. The price is right too. You can get a brand new complete set of Cobra Speedzone irons for around $600.

The Cobra Speedzone irons are definitely for high handicappers who need help in the distance and accuracy departments. While they won’t be able to help much as you lower your score; the relatively low price still makes them a decent value for high handicappers and beginners.

The Radspeed Irons from Cobra

Cobra also makes the Radspeed line of irons that are geared more toward mid to low handicappers.

If you are looking for better performance around the pin then the Radspeed irons would be better for you. They even come in single length sets if you want better consistency. The Radspeed irons are a more complete set as they are designed to play long while the shorter irons enhance spin control.

Distance: 93/100

Accuracy: 91/100

Forgiveness: 94/100

“The Cobra Aerojet irons would be a great choice for high handicappers looking to score a set that will still be of use to them as they improve.”

Forgiveness: 96/100

Workability: 94/100

Feel & Control: 95/100

Overall Score: 95/100
