A head suspension assembly in a rigid disk drive having a load beam with a mounting region, a rigid region and a spring region located between the mounting region and rigid region. The mounting region includes an integral boss tower having attachment features. A method of making a multi-piece head suspension for a rigid disk drive is also disclosed. The method includes providing a first layer including a mounting region with an integral boss tower attached to a stiffener by one or more positioning tabs; attaching a second layer including a spring region to an interface between the mounting region and the stiffener; attaching a flexure to the stiffener; and removing the positioning tabs. The flexure can optionally be a portion of the second layer.
