Build and customize your own JUPITER ONE Driver, 3 and 5 Wood Shaft. Our Brand New Steadfast JUPITER ONE 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.
