JUPITER 1 PLUS 3 Wood Shaft
- Description
- FLEX SPECS
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.

"Straightest Shaft in Golf"
Club Champions review and test Steadfasts superb Shafts
**Steadfast Shafts**
What's the big deal?!
Our mission is not just to outperform the competition, but to dominate it.
Made with..
Premium carbon fiber
Steadfast Golf golf shafts are an improvement to the typical graphite shaft, increasing the durability, performance, and overall feel.
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 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.
Let customers speak for us
“I thoroughly enjoy my Steadfast shafts. Well worth the cost when I hear my golf buddies tell me I made a great shot, especially since I have a high handicap!
”
“I LOVE THESE SHAFTS!!! I was skeptical about Jupiter at first. Then my friend and pro purchased the shafts and let me try them. I was sold. It's helped on mishits, shot dispersion and it does add distance to your swing!
”
“I have been extremely happy with my new Jupiter shaft. I have picked up 5 to 10 yards and the shot dispersion has improved as well. Highly recommend these shafts!
”
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.
