The Brand New Steadfast Jupiter One 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!
