Roadmaster 1139-212 is a 1-3/4-inch auxiliary rear anti-sway bar kit for approved Ford F-53 and F-550 motorhome chassis. Roadmaster's installation manual explicitly states to keep the factory rear sway bar installed; this kit supplements it rather than replacing it. Manufacturer parts include the bar, end links, mounting brackets, bushings, fasteners, lubrication and threadlocker. Extra U-bolts may be required: if the factory axle U-bolts are not long enough, Roadmaster specifies separately ordered 590050-00 for square-top or 590050-10 for round-top U-bolts. The chassis years listed below are potential applications, not blanket fitment for every GVWR, engine or suspension package. Confirm the chassis model year, axle U-bolt type, available clearance and Roadmaster FitMaster approval before ordering.
- Rear auxiliary 1-3/4-inch kit: retains the original rear bar; optional longer axle U-bolts may be needed for installation.
