Roadmaster Anti-Sway Polyurethane Bushings

Superior Construction

The lubricated bushings in your anti-sway system allow just enough pivot and rotation to compensate for the pressure placed on one side of your vehicle when it goes into sudden maneuvers, hits crosswinds or encounters shifting weights. These bushings, therefore, must be both durable and flexible. Polyurethane allows an appropriate amount of give and lasts longer than rubber, which is the standard material used in bushings, thus ensuring that the system is neither so rigid nor so malleable that it becomes ineffective.

Speaker 1: Today we're gonna take a look at the Roadmaster Polyurethane Bushing Kit for one and three-eighths inch diameter factory rear anti-sway bars on Class A motor homes. This is a custom fit part. It is designed to fit the 2000 and newer F-550 and F53 Chassis Class A motor homes and because it fits such a variety of vehicles, I would recommend to go to our website, use our fit guide, put in your year and model vehicle, and it'll show if this will work for your application.Now these replacement bushels will work with your factory rear anti-sway bar to improve the overall stability of your vehicle. The flexible design will help keep your anti-sway system from being too rigid and polyurethane is very durable and resistant to damage that can be caused by oil, gasoline, and ozone. Less wear will mean less give in your anti-sway system and better support.This part will include everything shown here on the table. Comes with the two split polyurethane bushings right here with the metal saddle brackets, four of the polyurethane bushings and sleeves, four of the polyurethane grommets, four large washers, four small washers, the eight bolts, a nice container of aqua lube grease that you'll apply to all your bushings when you install them, and a nice set of detailed instructions that'll describe how to install all these parts.

These parts are made in the U.S.A.That should do it for review on the Roadmaster Polyurethane Bushing Kit for one and three-eighths inch diameter factory rear anti-sway bar on Class A motor home.

Fairly easy to put on. Can't say that I notice an improvement in the ride or swaying of our motor home, but at least I have new bushing on the coach. 262286

Ask the Experts about this Roadmaster Accessories and Parts

  • Torque Specs for Roadmaster Bushing Kit # RM-4139-300
    I spoke with my contact at Roadmaster regarding any torque specs when installing the Bushing Kit # RM-4139-300 that you referenced. He said that for the bushings themselves there isn't a recommended torque spec because you really just want to tighten them enough so that the bushing is being squeezed a bit. Overtightening can cause damage so you want to be careful. For the saddle brackets it will depend on what size bolt you are using. For a 10mm bolt they recommend 37 foot pounds of...

  • Recommended Anti-Sway and Suspension Enhancement for 2020 Thor Minamar
    For your 2020 Thor Minamar, I recommend the Roadmaster Polyurethane Bushing Kit for 1-3/8" Diameter, Factory Rear Anti-Sway # RM-4139-300 which is a confirmed fit and the rear anti-sway has the most impact on the ride quality so this is the first element if you need to add parts in stages. This will help stabilize the rear end. For the front, I recommend the Roadmaster Polyurethane Bushing Kit for 1-5/8" Diameter, Factory Front Anti-Sway Bar # RM-4139-127. These combined will give you...

  • Suspension Enhancement for Itasca RV on 2014 Ford F-53 Chassis
    I recommend having your suspension checked out to make sure there are no issues, but if everything is fine, suspension enhancement springs would help level your Itasca. I could not guarantee this will "fix" your lean but the SumoSprings Maxim Custom Helper Springs # SSR-187-54-1 are designed to help keep your RV level and minimize sway. These springs are for 2-wheel drive models - as each of the available springs we offer are - with a GVWR between 20,000 and 26,000 lbs. As for the bushings,...

  • Replacement Anti-Sway Bar Bushings for Motorhome On Ford F-53 Chassis
    In order to replace just the factory anti-sway bar bushings on a Ford F-53 Chassis you have a few options which will be based on the location of the anti-sway bar (front/rear) and the gross vehicle weight rating of the coach (15,700 lbs, 16,000 lbs etc.) or diameter of the factory sway bar (1-1/2", 1-3/8", or 1-5/8"). If you need bushings for a front anti-sway bar and it is 1-5/8" diameter then you can use the Roadmaster Polyurethane Bushing Kit part # RM-4139-127 but if you need bushings...

  • Replacement Poly Bushings for Rear Anti-Sway Bar on a 2011 Tiffin Allegro on a Ford F-550 Chassis
    Rear poly bushing kit # RM-4139-125 is indeed a fit for your 2011 Tiffin Allegro built on a Ford F-550 chassis. Roadmaster notes that some of the endlink parts may not be used in the installation and that the fit assumes a 1-1/2 inch OEM bar. Your bar at 1-27/64 inches (1.42 inches) is very close but ultimately too small for a proper fit and you will need a different option. The other option is # RM-4139-300 for a 1-3/8 inch diameter bar. This is actually closer to the 1.42 inch...

  • What is the Difference Between the Different Color SumoSprings for the 2019 Coachman Mirada 32SS.
    You are correct that the different colors on the SumoSprings Custom Helper Springs like the # SSR-187-54-1 note the different densities of the springs; the yellow springs that you were looking at and are mentioned above are the stiffest compression strength springs available for your 2020 Coachman Mirada 32SS and are the best choice to help reduce the side-to-side sway you're experiencing. For reference, the blue SumoSprings are for light duty applications, the black are designed for...
