The ACCRA iSeries Driver Shaft is designed with a proprietary weave in the butt section to enhance stability while maintaining a smooth, responsive feel. Its shorter bendable beam length and active tip section are engineered to increase clubhead speed and launch without sacrificing control. This driver shaft forms the core of the iSeries lineup, offering performance-driven design with updated graphics to match the full iSeries family. When paired with DyMatched fairway and hybrid shafts, it delivers a fully integrated, consistent setup across the top end of the bag.Specifications Model Flex Mass Length iW4 M0 47G 46" iW4 M1 49G 46" iW4 M2 49G 46" iW4 M3 52G 46" iW4 M4 55G 46" iW5 M2 57G 46" iW5 M3 58G 46" iW5 M4 62G 46" iW6 M3 63G 46" iW6 M4 67G 46"
