This past spring I purchased a 910D3 driver with an up-charge shaft and would like to upgrade it to a 913D3 driver when it is available. Will the SureFit shaft from my 910D3 driver fit on the new 913D models?
Yes. The surefit hosel from the 910 drivers are the same as the 913 hosels. However, the fairway models will have differen't ones.
Yes, the 910 driver shafts will be compatible with the 913 driver shafts.
