A vehicle frame assembly includes first and second generally parallel chassis rails. At least one of the first and second chassis rails has a first portion defining an internal cavity and at least a second portion defining an enclosed passageway extending along the first portion and within the internal cavity. The at least one of the first and second chassis rails is configured to be coupled to a first component and to provide a routing within the passageway between the first component and a second component.
