ABSTRACT:
An adjustable golf shaft having an upper shaft member, a lower shaft member and a torque resistant mechanism. The adjustable golf shaft includes an upper shaft member having an elongated bore therein, an outer torque resistant member having a substantially cylindrical shape and secured to an inner surface of the upper shaft member, a lower shaft member having a flared upper end configured to fit within the inner surface of the upper shaft member, and an inner torque resistant member having a substantially ring shape and secured to an outer surface of the lower shaft member. The inner torque resistant member is slidably engaged into the outer torque resistant member and configured to prevent the inner torque resistant member from rotating relative to the outer torque member, to thereby form a torque resistant shaft.
