JUPITER 1 PLUS Driver Shaft Custom Build

$119.00

Build and customize your own JUPITER ONE PLUS Driver, 3 and 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.

Straight down the fairway

This would be my second shaft one on a taylormade tip and the second is on my new G425 max . I had to change the grip but I knew that before I ordered it, Now I hit them straight down the middle

Kudos!!!!!!

So I have tried a number of shafts my last one being one that retailed around $318 bucks. I thought it was going to get me what I was looking for but I hated it and put yours back on. I will never change again unless I buy from your company. I have two and will say that yours have been the best. Definitely the best ones I have. Thank you

Good shaft for the money

You can pay a lot more money for a shaft of this quality

Best money spent

My new driver shaft has helped with dispersion and a little more distance. For the money, it was the best money spent. I don't think spending $300 to $500 for an upgraded shaft is a waste a money. I'm so glad I took the chance and gave this product a chance. Now thinking about ordering a 3 wood shaft.

**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.

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🤣🤣

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 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.
