Complete Guide to Project X Flex Codes

Have you ever wondered what the number designation on your Project X shaft means? You know, the 5.0, 6.0, 6.5 and so on printed on the shaft. These numbers correspond with flexes from “regular” to “extra stiff plus”. While the flex is sometimes written on the shaft, many times it isn’t, leaving only the number to inform you of the flex. The only problem? The flex that corresponds with each number often changes based on the shaft model. And the power of Google can fail you as you search for a cohesive list of all of the flex code meanings. Even the Project X website lacks any kind of compiled guide, and only some of the individual shaft product pages reveal which numbers go with which flex.

Not to worry. We’ve created an extensive list of Project X shafts and their flex codes. We’ll update the list as more shafts are released in the future.

It’s important to note that there has been much discussion around the designation of flex for Project X versus other shafts. A “stiff” flex from one shaft producer will not always equal a “stiff” flex from another. While these codes are accurate based on the flex that Project X indicates, your mileage may vary on how well the feel of the shaft matches the maker’s designation.

  1. I’m trying to find out the weight of the PXv 6.0..? Is there a chart for that. (PS: The Project X website is near useless. You’re right about that.)

    Thx.

  2. harika bir paylasim

  3. Excellent info; exactly what I was looking for.
    Many thanks!

  4. May I simply say what a comfort to uncover someone
    who genuinely knows what they’re discussing on the
    net. You actually know how to bring an issue to light and
    make it important. More and more people must read this and understand this side of
    the story. I was surprised that you aren’t more popular because you
    definitely have the gift.

  5. Very very good info! Now I have good understanding what the numbers mean. One of the most important things to know, is the flex that fits your swing! It makes a huge difference in your game.

    Thanks again

    1. That is absolutely 100% on the money right there I have a very same take away and same down in through Tempo swing repeatable every time and my swing is like 80 5 to 89 miles an hour before I got hurt so I was hitting some taylormade’s he brought me last year in the fitting room as soon as he give me the mizuno’s the first ball I hit I knew it was a rocket I never felt nothing so good in my life I was in love I told him go get them I will take them

  6. I know I got a set of jpx 900 hot metal and he put me graphite shafts in their Project X they are 4.5 and 70 I hit a straighter than I’ve ever hit any club in my entire life I am 54 I quit playing golf for 6 years because of a stroke ahead on my left side but it wasn’t that bad and I used to could hit a 7 and 45 yards all out now 140 yards with the graphite shafts and they’re twice as high in the air I would never had anything that felt so wonderful in my life they are on the money I got to play a about 2 months and then my shoulder went out I make sure she’s to get back out there I had bought a TaylorMade M2 for my dad but he is 80 and he just don’t have the speed to swing it I can’t even swing it they said if you can swing a hundred miles an hour don’t even bother to buy TaylorMade what one of the guys told me so I go to Eagle Zone they put me on that machine and guess what they sold me am-4 twist face 1 inch shorter shaft I paid 480 something dollars for it to come 6 weeks to get it to me and I went out there and I could hit my 3 wood hot X2 by Calloway 20 yards further than I could hit that driver and I went back in there I should hear give me my money back y’all don’t know what y’all doing and they give me my money back so now I’m swinging the Ping 2000 17 model I think it’s the 300 series regular shaft and I hit it just fine or I was hitting it just fine until this happened I hope you can get this thank you sir

  7. Yes the 4.5 means senior shaft the 70 means the grams and the flex of the shaft that’s what the guy from Mizuno told me like 70 is extra stiff the way I understood it is that right or wrong thank you
