JUPITER 1 PLUS Driver Shaft

The Brand New Steadfast JUPITER ONE PLUS Driver Shaft was 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!

Golf Laboratories (leader in independent testing for the golf industry) recently put the Steadfast driver shaft to the test.

Steadfast shaft reduced mishit dispersion by 50% (28 yards) against other premium (much more expensive) shafts manufactured by industry-leading brands.

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 the competitors.

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.

FITS ANY BRAND 
Our premium carbon fiber shafts are 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 shafts are engineered and tested individually by flex, meaning each flex is a completely different formula that has been optimized with hundreds of revisions and thousands of hours in the simulator and robotic testing.

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