Steadfast Carbon Fiber Driver Shaft - Carbon Fiber Golf Shaft with Standard 45.5" Play Length - 4 Flex Choices - Tour 360 Grip - Adapter Included - Installed Professional Club Fitting Team

Last year I was fitted for a new set of Callaway Mavrik clubs. I was fitted for regular shafts but my driver always felt a bit whippy and gave me really erratic results, particularly when I swung harder. So, I thought I would try out a stiff shaft and came across this new carbon fiber one on Amazon,(which is different than the normal graphite material) and was made in America (which is a plus to me).I am really pleased with the performance of this shaft. It made a huge difference. I was absolutely crushing the ball on my first round out with it. It’s the first time in a while that I felt like I could swing all out and not pay a heavy price with a miss hit.

Great product and fast shipping. Replaced my stock shaft on my Sim2 driver with a steadfast shaft and instantly seen a huge difference off the tee. Hitting further and straighter. My 2nd round using this set up I shot a personal best score. I highly recommend this product!

Replaced my regular flex with an extra stiff. Used it last night. 260 off the tee time after time. Love my big Bertha again.

Ordered a regular flex on my 3 wood and after a few swings my fade was less and added 10 to 15 yards. Was so pleased that I ordered 1 for my other set of clubs.

This shaft is living up to its billing, I am hitting it straighter, thou it is still the craftsman and not the tools sometimes....(if I revert back to my old ways, I can still hit it poorly), but it does have a different feel from my previous shaft. Very happy with it and we all know how trust and confidence in your equipment really goes a long way in results.

Really love this driver shaft. It’s a quality product and delivery was prompt.

Way shorter than 45".5The length is only 43".5...Wrong description...

Awesome shaft
