Steadfast carbon fiber golf shafts are an improvement to the typical graphite shaft, increasing the durability, performance, and overall feel of any club.

Our shafts have gone through rigorous testing procedures to assure each shaft is not only made to our high standard of quality but also performs exactly the same no matter which shaft is being tested from production.

With increased weight balance and our special low torque design, we guarantee you will experience longer distance with low spin dispersion. Whether being tested by robots, pro golfers, or amateur players, the Steadfast Shaft will deliver consistent results and is an easy switch to make with any popular clubhead manufacturer.

INCREASE DISTANCE 
Optimized head to shaft weight balance means an easier swing through the ball allowing the club to lead the hands through impact to naturally increase distance increasing ball carry while getting the proper RPM.

LONGEST AND STRAIGHT BALL FLIGHT 
Tested as the straightest shaft in golf with the least amount of dispersion. Hitting a straighter ball requires low shaft torque. The new Steadfast shaft was designed with torque and balance as the number one priority, leading to the best feeling and most stable shafts on the market.

REFINED GRAPHITE
Graphite shafts tend to be brittle and do not stand the test of time, Steadfast is constructed using the highest quality carbon fiber which is the pure form of graphite providing more durability and a better overall feel.

FITS ANY BRAND 
Our premium carbon fiber shafts are also easy to set up and attach, simply prepare the tip and adapter then attach your existing head.

OPTIMIZED THROUGH TESTING 
Our shafts are engineered and tested individually by flex, meaning each flex is a completely different formula that has been optimized with 100’s of revisions and 1000’s of hours in the simulator and robotic testing.

    To ensure the highest possible quality the adapters and grips are installed by the world-class pro tour club fitters.

    Shafts and adapters are suitable for both right and left-handed golfers.

    Quality product

    The shaft was a great addition to a previous bought club that I could not hit well. With the new shaft I am more accurate and consistent with my fairway shots.

    Put this in a new Adams 5 wood recently. High launch and straight. dispersion is a lot tighter. Great value shaft.

    Like the two other Driver shafts I ordered, the accuracy and feel of the 5 wood shaft is awesome.

    New 5 wood shaft

    This is my 5th or 6th shaft I have purchased. (due to using different brands of clubs) I have been, and am very satisfied with their performance. They are the most accurate I have ever used.

    5 wood shaft

    Alright my honest opinion on the Steadfast fairway shaft in (stiff) flex. I don’t get paid by them by know means I’m an average golfer at best a 10 handicap with avg club head speed at 95-105 according to trackman. The Callaway paradym with stock was sus at best when I switched to the Steadfast I noticed a bounce right of the club meaning it shot right off the whip sound from the shaft is amazing it’s something that you know you hit it well and I’m not gonna complain or make excuses if you hit farther then some of your buddies Drivers 🤷🏽‍♂️
    Give it a shot it’s my second purchase cause I do carry a steadfast for my TaylorMade stealth 😵‍💫 crazy accurate

    Head to shaft weight balance

    This means an easier swing through the ball, allowing the club to lead the hands through impact to naturally increase distance increasing ball carry while getting the proper RPM.

    Golf Laboratories Tests:

    Reduced mishit dispersion by 50%

    ...That's 28 yards against other 'premium' expensive shafts.

    In other words, if you hit it off the toe or heel, it continues to go straight for the same distance. 

    Ball speed increased slightly for the Steadfast shaft and backspin was better or equal to competitors.

    Black stealth look. Dispersion is much better than the stock shaft my driver came with. I've noticed increased distance and would recommend anyone to try this shaft.

    Golf Driver With a Steadfast Driver Shaft Looking From the Top Clubhead Down

    Phenomenal Shaft! I have never driven the ball straighter, longer and stayed in the middle of the fairway. All my drives are going over or close to 300 yards. Keeping this secret from my buddies for this season🤣🤣

    I was complete shock in my first couple of shots with my driver. For the cost, great appearance & performance it is totally amazing. Great launch, very tight ball dispersion and ball length I believe has increased. I am truly considering placing a Jupiter shaft in my 3 wood. I would not hesitate to recommend the Jupiter shafts to my friends.

    Mishit Dispersion Graph Showing How Steadfast Driver Shaft Reduced Mishit by 50%

    numbers don't lie

    HERE’S WHAT THE TESTING SHOWS…

    The below data was collected using the same TaylorMade M5 driver head (set at the same loft) with three different shafts: 


    - Steadfast

    - Shaft A (major aftermarket shaft manufacturer)

    - Shaft B (major aftermarket shaft manufacturer)

    >
    Head to head
    Steadfast Shaft A Shaft B
    Ball Speed 172 168.1 166.5
    Backspin 1,813 2,420 2,689
    Carry Yards 288 278 276
    Total Yards 313 301 298

    So...

    What does this mean for me?

    To summarize, the data shows that Steadfast Shafts come out on top for all three metrics::

     

    ✔️ DISTANCE: 10-15 more yards of carry and total distance
    because Steadfast shafts produce more ball speed and less backspin.

     

    ✔️ ACCURACY: 25% fewer mis-hits and dispersion because of Steadfast’s extremely low-torque shafts reduce sidespin.

     

    ✔️ CONSISTENCY: Steadfast shafts are precisely weighted and effectively “spineless,” so kick points remain consistent even when adjusting
    driver heads.
