Get a special price for buying one of each shaft. Our 3 Shaft Bundle contains:

1 x JUPITER ONE PLUS Driver Shaft

1 x JUPITER ONE PLUS 3-Wood Shaft

1 x JUPITER ONE PLUS 5-Wood Shaft

 

Our Brand New Steadfast JUPITER ONE PLUS Shafts are designed with torque and balance as the number one priority, leading to the best feeling and most stable shafts on the market.

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.

When you strike the toe or heel, you’ll still find your ball in or near the fairway. You’ll still get solid distance, too, as the test results proved.

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

If you are looking to drive longer and/or straighter this is the shaft for you!

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

3 great shatfs

I purchased the 3 club bundle and added one more 5W shaft for my 7W and I can say that was a great investment. All my woods are straiter and longer and very consistent as discribed on the website.
I highly recomend these shafts for golfers that want consistency with tee and fairwat shots.

Love Steadfast Shafts

I ordered these shafts to use in my hybrids. I did have to add a shim because the tips are .335 and my hybrids are .370. No big deal, I have played a round with the new shafts in my hybrids and love the way they play!!! Awesome!!! Thanks Steadfast!

What's the big deal?!

Our mission is not just to outperform the competition, but to dominate it.

HERE IS HOW WE DO IT

DRIVER SHAFT MADE WITH...

Premium carbon fiber

Steadfast Golf driver shaft is an improvement to the typical graphite driver shaft. Why? Carbon fiber increases the durability, performance, and overall feel. You get more value for less.

Perfectly optimized

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 Driver Shaft 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. 

Finally, ball speed increased slightly for the Steadfast driver shaft. Furthermore, 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🤣🤣

Golfer Wearing Glasses Holding a Steadfast Driver Golf Shaft and Smiling

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 Driver 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 driver shafts reduce sidespin.

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