- Description
- DRIVER SHAFT FLEX SPECS
Get a special price for buying one of each shaft. Our 3 Shaft Bundle contains:
1 x JUPITER ONE PLUS Driver Shaft plus one of each 3 or 5 Wood Shaft combo.
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.

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.
