TaylorMade SIM2 Max OS Irons Review

50 Words or Less

The TaylorMade SIM2 Max OS irons are slightly larger and more forgiving than the SIM2 Max.  Very strong lofts produce lots of distance.


Typically, taking things “to the max” means taking them to their limit.  However, with TaylorMade’s newest irons, the limit is not the SIM2 Max irons [review HERE] but the SIM2 Max OS.  The OS (oversized) version is larger, more forgiving, and capable of producing even longer approach shots.

Check out the latest TaylorMade game improvement iron, the Stealth, HERE


The SIM2 Max OS irons straddle the line between game improvement and super game improvement.  This set has what TaylorMade describes as an “oversized” face profile and a substantial amount of offset.  The top line is thick as is the sole, but the sole does not protrude beyond the top line at address.

In the bag, the SIM2 Max OS looks much like the SIM2 Max but with a deeper cavity.  Like its smaller brother, the OS has a bold, high-tech look, but it eschews color in favor of many shades of silver.

Comparing the SIM2 Max (left) and the SIM2 Max OS, you’ll notice that the top lines are very similar in size.  The most obvious difference at address is the additional offset in the OS model.  A 360 degree inspection will also reveal a wider sole and deeper cavity on the OS.

Sound & Feel

Something I’ve noticed and admire in the SIM2 line is that TaylorMade has kept the feel very consistent between different models.  Each of the SIM2 drivers had the same wonderfully solid impact feel even as they go from draw-biased to Tour-style.

I found that same consistency between the SIM2 Max and SIM2 Max OS irons.  Admittedly these two irons aren’t worlds apart, but maintaining the same feel is still commendable.  The SIM2 Max OS irons are slightly above average in volume with a sound and feel that sits between solid and explosive.  Like the SIM2 Max, there’s enough feedback through your hands and ears to tell a miss from a pure strike.


I took the SIM2 Max OS irons to the range alongside the SIM2 Max irons, and the family resemblance in performance was unmistakable.  Like its smaller brother, the SIM2 Max OS just wants to launch the ball into the sky, regardless of contact quality, and send it screaming downrange.  Outdoors, I perceived a medium trajectory very similar to the SIM2 Max with medium-low spin and a lot of distance.  The standout trait was the consistency of the results.

When I got the SIM2 Max OS irons into the testing bay, I saw more of the same.  The lofts of the SIM2 Max OS irons are even stronger than those in the SIM2 Max, but the wider sole and lower CG causes them to launch at similar angles.  The SIM2 Max OS spins even less than its brother.  This is great for producing distance, but it can be problematic when you want to hold a green.  As always, make sure you get fit for your irons.  The right shaft or a small spec tweak can get you the distance you want with the ability to control your shots.

All the forgiveness and consistency I found in the SIM2 Max irons was taken up another small notch in the SIM2 Max OS.  Thanks to all of TaylorMade’s signature technologies – Cap Back Design, Thru-Slot Speed Pocket, and Progressive ICT – these irons produce a ton of ball speed whether you hit it pure or toward the edges of the face.  Also, the aforementioned low CG does wonders for putting thin shots on playable trajectories.


If you want all the forgiveness that money can buy, the TaylorMade SIM2 Max OS irons need to be part of your fitting.  These irons are extremely consistent and easy to hit.  Make sure to get the right shaft and you’ll be hitting long, straight approach shots this season.

    I hope this is not too off topic I am somewhat confused when I see what one would think of as a driver or fairway shaft in irons. Is the Ventus Blue really similar to the Ventus driver shaft? Is this a shaft that Fujikura sells as a iron shaft or is this just a Taylor Made thing?

    • Matt Saternus


      Fujikura’s website doesn’t show a Ventus iron shaft, so it appears to be a stock only offering for now.

    Hi Matt,
    I was just wondering is there a substantial difference between the TM Sim max OS irons of 2019 vs these new TM Sim2 max OS irons? Other than the cosmetic differences and the support bar, is the feel and sound better?
    Thank you

    • Matt Saternus


      I would not use the word “substantial.” With few exceptions, when we’re talking about one generation vs. the next, the differences are going to be incremental.

    I just purchased a set of TM Sim 2 Max OS Irons and was curious why the horizontal line on the bottom of the club was only on a few of the irons. I think the line is on my 5-8 iron but not anything after that. Just curious??

    • Matt Saternus


      The Speed Pocket technology is not incorporated into the scoring irons, presumably because there is not a need for as much forgiveness in those clubs.



  4. So I went and got fitted for the Sim 2 Max OS today. I had originally planned on just the Sim 2 Max. I was blown away by the OS. Gained at least 15 yards with the OS and increased my Club speed by about 12mph. Granted I was hitting barefoot, off turf, indoors, but holy cow! I’ve never hit a 7 Iron 170 yards. I had just purchased the Cobra F-Max and was discouraged after about 4 rounds. My question is this; I was never able to successfully hit the hybrids that came with the F-Max irons. Should I just stick with the standard OS irons, or go ahead and invest in the 3 hybrid? Thanks!!

    Sorry but these SGI iron sets that Calaway and TM release with every single new driver model are just expensive box sets. I think a better look would be if Callaway and TM gave their SGI irons their own identity and improved upon them over the years rather than slapping the name of their newest driver on them, rinse and repeat. They must sell so what do I know, lol.

    I am looking to get these for my fiance. She relatively new to golf, but I think she is already swinging harder than her cheap starter set can handle. She hits a 7 iron about 115-120. Debating between the Sim 2 Max and Max OS. I will be getting the combo set with two hybrids. My first instinct is to get her the OS, but wonder if it wouldnt be better to get her something she can grow into. She also seemed to prefer a smaller blade style wedge (as opposed to one of the bigger game improvement ones) when we tested and bought her one last week. Neither of the stores near me had these available to test in women’s shafts. Any thoughts would be appreciated.

    • Matt Saternus


      If she can’t get fit, I would get her input on which one she prefers visually, let her know the pros and cons of each set, and then let her make the call.



  7. Im relatively new at this sport, yet i managed to buy these irons a few months ago and i cant explain how fun the game has became to me since. Also cant say if i have dramaticaly improved my skills or the clubs are just hiting proper shots by themselves.

    I hope my experience helps someone out there who is still having second thoughts about buying these.

  8. I’m looking to get more into golf and definitely don’t have a reliable swing as yet (although the power is there when it does go right). I’m definitely prone to the right to left shot (that the OS claims to neutralise) and hitting thick/think and everything in between! In my head the OS feels like too much of a ‘cheat’ club, and hides bad shots. Do you think the Max version supports a more natural game development or am I just making life more difficult for myself if I didn’t get the OS at this stage of my game?

    • Matt Saternus


      There is no such thing as a “cheat” club in golf. There are guys on Tour who have won with irons similar to the Max OS. No club will help you find the center of the face, no club will fix your club path or face angle at impact.
      None of that is to say that you need to play a more forgiving club, only that it’s a perfectly fine option for any player to do so.

    I just purchased the TM Sim 2 OS iron set, 5-SW, senior flex, graphite shaft. played the once so far and loved them. They do everything promised. I bought these to replace my 2013 TM SLDR Iron Set stiff flex.

  10. I’m a big fan of TaylorMade’s irons. I own a few of their models and have never been disappointed. The SIM2 Max OS irons are no exception. They are well-made and look great on the golf
