Attach these durable, flexible polyurethane bushings to the rear anti-sway bar of your vehicle and experience a better, more controlled ride.
Features:
- Replacement bushings work with your factory, rear anti-sway bar to improve the overall stability of your vehicle
- Flexible design keeps anti-sway system from being too rigid
- Polyurethane is durable and resistant to damage caused by oil, gasoline and ozone
- Less wear means less give in your anti-sway system and better support
- 2 Bushings and necessary hardware included
- Made in USA
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.

Product is great but make sure you get the correct size. This is for a 1 1/2" rear sway bar. Don't trust the fitting guide. Even though I have a 22K chassis, my sway bar is 1 3/8". Fortunately, Roadmaster has excellent customer service and fixed everything for no charge.

When looking at replacement sway bar parts, it is important to double check both the coachs GVWR as well as the diameter of the rear sway bar. Our fit guide lists 3 different replacement bushing options for the 2016 Newmar Bay Star 22,000 lb GVWR: 1-1/2 inch kit # RM-4139-125

The sway bar assembly and overload spring items for my F53 rv arrived as scheduled. All parts were packed well, so there was no shipping damage. Very pleased with products, and instructions were easy to follow. Have already installed new sway bar system, front and rear spring overloads. While installing new sway bar system, noticed factory swag bar needed new bushings. Ordered them from etrailer, and they arrived in a week. Very pleased and would recommend etrailer to friends.

- Does Roadmaster Polyurethane Bushing Kit # RM-4139-125 Need Nuts to InstallSince the bolts that come with the Roadmaster Polyurethane Bushing Kit # RM-4139-125 are designed to attach to threaded parts of the vehicle suspension nuts are not included or needed. Check out the install video I attached for more info on how it installs.
view full answer... - Do the Roadmaster Replacement Bushings Need to be Pressed In for the Install?Some of the bushings on the Roadmaster # RM-4139-125 will need to be pressed in, but it is not overly difficult. I included an install video we have of a similar Roadmaster kit that will show how this needs to be done.
view full answer... - Replacement Poly Bushings for Rear Anti-Sway Bar on a 2011 Tiffin Allegro on a Ford F-550 ChassisRear 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 bar...
view full answer... - Anti-Sway Bar Bushings For 2005 Ford F-550 Chassis Class A MotorhomeWe do have bushing kits for the OEM anti-sway bar on your Sea Breeze built on a 2005 Ford F-550 chassis, and the bushings include the brackets as well. There are different bushings depending on the diameter of your anti-sway bar, so you will need to measure it to ensure you get the right kit, and I'll list out the options for you: - Rear 1-1/2" Diameter Bar: Roadmaster Polyurethane Bushing Kit for 1-1/2" Diameter, Factory Rear Anti-Sway Bar # RM-4139-125 - Rear 1-3/8" Diameter Bar: Roadmaster...
view full answer... - Upgrading to Polyurethane Anti-Sway Bar Bushing On a 1998 Damon DaybreakThe Roadmaster Polyurethane Bushing Kit part # RM-4139-127 for front and part # RM-4139-125 for rear are correct for a 1998 Damon Daybreak. We do offer just the replacement bushings for these but they are not designed to be used with the factory brackets. If done so, you risk the chance of the bushing slipping out causing damage as well as risking losing control of the motorhome. I don't have any dimensional drawing of the replacement bushings unfortunately.
view full answer... - Replacement Bushing for Rear Sway Bar of 2007 Fleetwood Bounder 33RWe do have replacement bushing and mount kits that fit your 2007 Fleetwood Bounder 33R for the rear sway bar but it depends on what the diameter of your factory bar is. If the diameter is 1-3/8 inch you'd want the part # RM-4139-300 or if it's 1-1/2 inch # RM-4139-125. Since there's no way for us to know which diameter bar you have now you'll have to run out and measure to determine what you'd need.
view full answer... - Replacement Anti-Sway Bar Bushings for Motorhome On Ford F-53 ChassisIn 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...
view full answer... - What is the Rear Sway Bar Size of a 2002 Ford F-53The only way to know if the Roadmaster Polyurethane Bushing Kit for 1-1/2" Diameter, Factory Rear Anti-Sway Bar # RM-4139-125 will fit the rear sway bar on your 2002 Ford F-53 chassis is for you to measure them using a Digital Caliper, like part # PTW80157. Since different RV manufacturers will install their own preferred equipment on any given chassis you have a much more guarantee of a fit if you can check the measurement physically.
view full answer... - Rear Factory Anti-Sway Bar Bushing Upgrade for 1999 Fleetwood Bounder 34v on Ford F53 ChassisI did some checking on your 1999 Fleetwood Bounder 34v and it appears that it was built on the Ford F53 chassis which is a common one for Class A RVs. There is a bushing upgrade kit for the rear anti-sway bar and it is # RM-4139-125. The single bushing # RM-205217-10 may not work in the factory mounts by itself which is why I recommend going with the whole kit.

These are definitely better than the factory bushings that are used and would be a good place to start.

While there isn't a bushing kit designed for the factory anti-sway bar of your 2000 F-350, there is a replacement front anti-sway bar: - Roadmaster Front Anti-Sway Bar # RM-1139-155

So for the front axle use the Roadmaster TruTrac, # RM-TRACV-10B. For the rear you can upgrade the factory sway-bar bushings with kit # RM-4139-125. Upgrading just the bushings will also help provide a more stable ride compared to the stock bushings. I have included a link to our help article on...
