Roadmaster 1139-147 is a 1-1/2-inch rear factory-replacement anti-sway bar kit for selected Ford E-350 and E-450 cutaway Class C motorhome chassis. Roadmaster's Ford application chart lists the E-350 Class C for 2018–2023 and E-450 Class C for 1997–2023, with the important qualification for applications without automatic tire chains. This is a replacement for the factory rear bar, not an auxiliary bar fitted alongside the original. Installation hardware is included, but confirm chassis year, installed suspension, tire-chain equipment and clearance in Roadmaster FitMaster before purchase. Ford chassis fitment must not be inferred from motorhome coach model names alone.
