Abstract: Link arms for use in suspension systems are produced through an extrusion and friction stir welding process. Blocks having an eye and a planar body section are formed through an extrusion process. These sections are then paired together and joined through friction stir welding. The welded joint(s) is/are positioned in such a location so as to not impact the structural integrity of the completed component. Through this process it is possible to construct cost competitive link arms having the same or better structural integrity as previously employed steel link arms while achieving dramatic weight reductions.
