Abstract: An insert disposed between two cooperating leaf springs. The insert includes a body including a stem having a plurality of radially extending ribs inserted into an aperture in a first leaf spring. The body includes a face which slidably engages a second leaf spring. The face includes a plurality of circular protrusions extending therefrom. A pin is inserted into a central bore formed by cooperating fingers that form the body, causing an outwardly extending radial retention force to be exerted onto the surface of the aperture in the first leaf spring.
