A ball screw and nut assembly includes a ball screw component having a threaded outer surface and a ball nut component having a bore in which the ball screw component is received. The ball nut component includes a threaded inner surface that cooperates with the threaded outer surface of the ball screw component to achieve axial movement of the ball nut component between a fully retracted position and a fully extended position as the ball screw rotates relative to the ball nut. A positive stop prevents rotation of the ball screw component relative to the ball nut component at an axial position between the fully retracted position and the fully extended position as the ball nut component is retracted.
