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.

Video Transcript for Roadmaster Anti-Sway Bars RM-4139-300 Review

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

Do you have a question about this Accessories and Part?


  • 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 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...

  • Roadmaster Vehicle Sway Bar and Steering Stabilizer Recommendation for 2019 Winnebago Intent 31P
  • Your 2019 Winnebago Intent 31P is built on a Ford F53 Chassis and based on the GVWR of 18,000 lbs I will make my recommendation for the correct front and rear anti-sway bar as well as the steering stabilizer below: # RM-1139-140 - Intended to replace an 1-3/4 inch diameter OEM front sway bar # RM-4139-125 - Intended to replace an 1-1/2 OEM rear sway bar OR # RM-4139-300 - Intended to replace an 1-3/8 OEM rear sway bar Note that some of the endlink parts may not be used when installing...

  • 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...

  • Correct SumoSprings for 2020 Mirada on Ford F-53 Chassis
  • The correct SumoSprings that fit your 2020 Coachmen Mirada depends on what the GVWR is for your RV, but don't worry because we have a fit for all 2019 Ford F-53 options so you just need to choose from the list below (and/or let me know what model Mirada you have): Front Axle 16K - 22K - # SSF-170-40-2 24K - 26K - # SSF-173-40-2 Rear Axle 16K - 18K - # SSR-184-40-1 20K - 22K - # SSR-180-54-1 24K - 26K - # SSR-183-54-1 Other upgrades you can add to your Class A RV are front...
