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.

After one year of use, the bushing are still going strong. They really helped stabilizing our class A motorhome from passing vehicles like 18-wheeler, which also helps make the drive less fatiguing. Fast shipping and easy to install. Highly recommend.

Placed an order an order an order right at tbe cut off for same day shipping, Explained my travel situation to Kim and that I needed the part ASAP, she said she would do her best to see it through, and we are very thankful she did, got the bushing kit installed and back on the road in 2 days. Polyurethane bushings look like a real nice upgrade over the factory rubber. Time will tell, the quality is good and everything fit as it should. The saddle bracket bolt had broke and bent the saddle braket on my F53 chassis, so my sway bar was floating and I was flat towing a truck, so I couldn't continue on as is. Thank you Kim for outstanding customer service.

The item came exactly when it was scheduled. The installation was simple, thanks to the great How-To video produced by etrailer. I’m a huge fan of etrailer and have shopped them almost exclusively since buying my RV. I’ll be back I’m sure.

Fast shipping and a perfect fit. Thanks

Perfect replacement clamps and hardware for factory installed rear sway bar. If your clamps are missing or the bushings are worn this is all you need. Fast shipment as well.

I like what the kit offered but I was unable to utilize all of it. My Ford F53 anti sway bar was loose due to missing saddle bracket and only one bolt holding the other saddle bracket. Due to potential damage to other bushings I ordered this kit. During installation of the saddle brackets I discovered that there were no nuts where the missing saddle bracket was supposed to be attached. The kit did not have nuts so I had to purchase nuts (and bolts).
When I tried to replace the link bushings I tried removing the old bushings exactly as advised in the instructions. However, the bushings would not break loose even trying to use a hammer to tighten the vise with the two different size sockets placed as instructed. Therefore I was not able to use the new link bushings (very disappointed). Overall, I was only able to use a small number of parts that came in the kit. The saddle brackets and bushings were all I could make use of and I had to purchase other parts.

Sorry to hear about your troubles when trying to install the end link bushings. I would try using a spray lubricant to help remove the small bushings that are pressed in place. You could also try using clippers or a sharp tool to cut out and remove the old hardened bushings.

Even without modifying the link bushings the anti sway bar repairs did make a noticeable improvement in vehicle handling. At this time I doubt doing anything with the link bushings would make any noticeable improvement so I will leave it as is.

@Ronald The benefit comes from the fact that the replacement polyurethane bushings are more durable than the stock bushings usually found. They are also resistant to deterioration caused by exposure to oil or gasoline.

Very fast delivery. Product has not been installed yet on RV’s rear sway bar, but looks as though it will work and improve the RV’s handling.



by:

Poly bushings are the only way to go. Installation is fairly simple when replacing your worn, cracked, or missing factory rubber bushings.



by:

Ashley, Amazed you had the part I needed and only two days shipping time and a great price.
My Motorcoach is 15 years old. I'll be installing them in the morning then I'm back on the road.
If I could, I'd give you 10 Stars.
Excellent, customer service.
Thank you etrailer is going in my contact list.



by:

The bushing kit was exactly as they advertised. The fit was perfect and installation was simple with the instructions provided.



by:

Parts arrived earlier than expected. Included additional parts and hardware not required for my application. Install time was just shy of 20 minutes start to finish. Did the job... Back on the road. Thanks etrailer.



by:

Ordered sway bar bushings on Tuesday got them on Thursday put them in Friday and went on a weekend trip Saturday. Got what I needed, got it fast. Thanks etrailer!



by:

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.



by:

I thought you sent the wrong parts, but you sent other parts for different sway bar. So ignore the 1st. Email I sent with pictures. It 97° outside. I'll change them in morning. Thanks!



by:

Whenever we purchase from you it is as expected and delivered on time. Really helped our motorhome with the anti sway added. Worth it for sure.

Product is great quality. But more important the Michele the service writer went above and beyond to get my order to me as soon as possible. More than great service. Highly recommend e-trailer.

  • 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...

  • Looking For Rear Sway Bar Bushings For 2011 Tiffin Allegro 30GA
    Hello Randy, thanks for reaching out. We have a few busing kits that may work for you. What we have are the Roadmaster Polyurethane Bushing Kits. These come in either a 1-3/8" # RM-4139-300 or a 1-1/2" # RM-4139-125. These are all made to replace the bushings for the OEM bar. There is no kit made for a 1.42" diameter bar, but it may be the 1-3/8" bushing is actually what you need.

  • 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...

  • 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 Bushing for Rear Sway Bar of 2007 Fleetwood Bounder 33R
    We 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.

  • 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 torque...

For a bushing kit for your factory bar you'd want the part # RM-4139-300.

  • 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 bar...

  • Recommended Rear Sway Bar For A 2005 Monaco Monarch On A Ford F53 Chassis
    Though we cannot see your cart, I can definitely tell you that if you are getting a lot of issues with sway and or body roll, I recommend going with the Roadmaster Rear Anti-Sway Bar # 1139-144. This is 1-3/4" thick 4140 chromoly steel for superior strength that will do a much better job than stock bars. With that said, this actually will not replace the original sway bar and you will keep that installed. So if your older bushings are looking a bit worse for wear, I do recommend getting...
