Roadmaster 1139-148 is a 1-3/4-inch front factory-replacement anti-sway bar kit for selected Ford F-53/F-550 Class A motorhome chassis. The manufacturer's Ford fitment chart lists 1998–2020 chassis with 16,000–26,000 lb GVWR; exact fit still depends on chassis generation and equipment. Roadmaster's installation parts list confirms the kit contains the sway bar, two replacement end links (B1013), bushings, clamps, fasteners and lubricant. This replaces the original front anti-sway bar rather than supplementing it. Confirm GVWR and Roadmaster FitMaster application before purchase; a coach's RV model year may differ from its chassis model year.
