- DRIVER SHAFT FLEX SPECS
The Brand New Steadfast Jupiter One Plus Driver Shaft is designed with torque and balance as the number one priority. This leads to the best feeling and most stable driver shaft on the market.
Our driver shaft head to shaft weight balance is optimized. This results in an easier swing through the ball allowing the club to lead the hands through impact. Ball carry and distance is naturally increased while getting the proper RPM. With increased weight balance and our special low torque design, we guarantee you will experience longer distance with low spin dispersion.
Additionally, 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 our 3rd party test results have proven. Whether being tested by robots, pro golfers, or amateur players, the Steadfast driver shaft will deliver consistent results and is an easy switch to make with any popular clubhead manufacturer.
Steadfast Jupiter one driver shaft is an improvement to the typical graphite shaft. This shaft increases the durability, performance, and overall feel of a driver. If you are looking to drive longer and straighter this is the driver shaft for you!
STRAIGHT BALL FLIGHT : Jupiter One driver shaft is tested as the straightest driver shaft in golf with the least amount of dispersion. Hitting a straighter ball requires low shaft torque, and this driver shaft was designed with torque and balance as the number one priority.
FITS ANY BRAND : Our premium carbon driver shaft is also easy to set up and attach. They are shipped with the adapter and grip already installed by our expert club fitters.
OPTIMIZED THROUGH TESTING : Our Jupiter One driver shaft is engineered and tested individually by flex. Specifically, this driver shaft flex is a completely different formula that has been optimized with hundreds of revisions and thousands of hours in the simulator and robotic testing.
Driver shaft and adapters are suitable for both right and left-handed golfers.

Customer Reviews
Awesome shaft, something is rattling in the shaft and the tip is not completely in stalled right . If you want to send me another one, I would send this back to you. I did already regripped it though!
My journey has been a nightmare, yes, you will get "shafted". I made my Jupiter shaft purchase on March 8, a Saturday. My purchase confirmation from SF Jupiter stated the shipping method: GROUND (Ships Next Business Day).So, I expected the driver shaft to be shipped on Monday, March 10th.The driver shaft wasn't shipped until 4 days after promised.
Unfortunately, this shaft isn't working for me. I purchased the senior flex based on my 77 mph driver swing speed. It's simply too whippy, the club head won't keep up with the swing. It's like swinging my orange whip swing trainer.
In the FAQ's - "We offer a 30-DAY FLEX SATISFACTION GUARANTEE: If you don't like the shaft flex you purchased, send it back and we will replace it." So I made a request to exchange to a regular flex. I used the Golf Shaft Selector Quiz to determine the proper flex based on my driver swing speed and driving distance, the result is senior flex by SF Jupiter standards.
I knew that return shipping would be on me but when I received an answer to my request to return the senior flex shaft for a regular flex, this is the reply "When you send the shaft back for exchange, as we do not offer refunds, please make sure to include a note stating the flex you will need. Once we receive the shaft back, we will invoice you for the professional adaptor installation and the return postage to you."
I feel Steadfast Golf is responsible for exchanging the senior flex shaft I ordered and replace it with a regular flex shaft without any invoicing monkey business! I just can't throw more money into something that's not a sure thing.

When arrived on my doorstep box looked like it got crushed but forgot to take picture but the shaft itself looked good and straight still but has something inside that's rattling. Not sure if it can effect the distance or but it did hit good when used it
Definitely an improvement over the shaft that was on my cobra
I bought this for my dad for an early Father’s Day present! He said it has added 15-20 yards per drive and his misses are not as far offline as before! He loves this driver shaft!

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.
HERE IS WHAT GOLFERS SAY
driver shaft reviews
Real golfers share their experience with the Jupiter One Plus Driver Shaft.
“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.
”
“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.

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.
