The RustBuster over-axle frame section for 2004–2008 Ford F-150 is the left-side replacement frame segment designed to restore the over-axle area. It replaces corroded or damaged frame material above the axle, helping re-establish structural continuity and providing the necessary mounting surface for suspension and body attachments in that frame region.
