Roadmaster Anti-Sway Bar Installed

Benefits of an Anti-Sway System

The Roadmaster anti-sway bar does for side-to-side movement what a good pair of shocks does for up-and-down motion. You will notice a marked improvement in your vehicle's stability as the bar works to balance weight transfer and reduce body roll. The anti-sway bar acts as a link between your vehicle's frame and its rear axle, using the axle as a brace to more effectively balance the shifting weight of your vehicle as you maneuver it. Lubricated bushings 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.


Roadmaster Anti-Sway Polyurethane Bushings

Superior Construction

The Roadmaster anti-sway bar is made of black powder-coated 4140 chromoly, a chromium and molybdenum steel alloy. This type of steel is considerably harder and stronger than the standard 1020 steel that is typically used in anti-sway applications. In addition, the larger diameter of the bar increases its torsional roll stiffness. The result is a bar that is not only stronger than the competition, but also nearly 30 percent better at resisting sway. The polyurethane bushings and grommets used at the attachment points are durable yet flexible, ensuring that the system is neither so rigid nor so malleable that it becomes ineffective.

Wow, This sway bar is big, heavy, beefy and strong. I saw all the great reviews but was still surprised when I got it. Installation was straight forward but I did have to have a mechanic shop jack the RV up and take the huge bolts of the U-bolts because my impact wrench was not strong enough. I've only put a few mines on it since I installed it but I have already noticed a difference.

Excellent product. Well made. Great instructions. Easy install with proper tools. Made an incredible improvement in the handling of our 35 ft MOTORCOACH with F53 chassis. All necessary hardware was included. Delivery and shipping by etrailer was spot on. Would definitely recommend to anyone wanting to greatly decrease sway in a coach.

Installed on a Tiffin Allegro 31SA by Whited Truck and RV Center in Auburn, Maine. The Roadmaster anti-sway bar and associated parts are rugged and of high quality. Installation time was about 3 hours; drilling the frame to secure brackets took the longest time. This anti-sway bar improved handing and reduced sway, especially on rough secondary roads.

I just received the product, which weighs in at "Over 70 pounds" according to the UPS tape attached, and will be returning it unopened once I receive the Return Authorization slip. Please note that this action had to be taken because of "Operator Headspace"on MY PART !!! I failed to properly read the requirements and limitations in their advertisement. The 1139-143 is for a motorhome with the Ford F-53 for an up to a max of 34 foot motorhomes. Mine is a 37 foot and need the one for 18,000 to 24,000 lb. My mistake and the correct one is on the way thanks to the help from the wonderful service personnel at etrailer.com. Great service for less than smart people like me... Thank you so much etrailer.com!!!

Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars


Overall, I am very satisfied with my purchase of the Roadmaster front anti-sway bar from etrailer. I had a few observations that I shared with etrailer and Roadmaster from my experience... I ordered part RM-1139-140 (Front Anti-Sway Bar), What I received did not match the information on the website. Meaning, the sway bar was slightly different than what was pictured and is shown in many of the instructional videos. The one I received also included end links. All of the information I had seen on the etrailer website indicated re-using the existing end links (etrailer website picture now shows picture with end links included). However, it appears the new end links provided are better and I like that, just wasn't what I was expecting and made the installation harder than I anticipated. In particular, it was difficult to remove the factory hardware where the end links bolt to the chassis due to the orientation of the bolts (need 18mm wrench). It also made me question if I had actually received the right parts...but I was able to get them installed and they seemed to fit. After talking to Roadmaster, they confirmed I had the right parts and had done a recent change to the product (now includes end links). The end links provided seem very robust, but the instructions were slightly confusing and unclear (to me at least) on how to orient the end links. It appears the correct orientation is for the "knuckle" of the end links to "point" toward each other. It took a while for me to feel like this was correct. The parts diagram was a bit unclear, but I shared this feedback with them and I understand they may be tweaking the instructions as a result. There also appeared to be some other inconsistencies or errors in the provided instructions. The instructions indicate to re-use hardware from the factory brackets, however they also provide new hardware in the kit (I used the new hardware provided). The new bolts were slightly larger than the factory bolts and at first I thought would not fit the axle mounting holes. A light tap with a hammer got them in without damaging the threads. All-in-all, I got it installed and it made a significant reduction in sway on the interstate. I can also corner the curves on the back roads without feeling like the rig is going to tip over. I also have the Rear Anti-sway bar and Steering Stabilizer from Roadmaster. I am very satisfied with my purchase from etrailer, the products, and the support from Roadmaster in answering my questions.

Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars


Considering the difference in diameter from stock to this upgrade I could feel the difference while driving. Easy to install with one minor obstacle. The factory left drop link bolt was installed between the fuel tank and the link mount which required us to remove the rear fuel tank bracket and pull the tank out far enough to pull the factory bolt out. The new bolt was installed towards the tank. Installed on ‘99 Dodge Ram 2500 4x4.

Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars


Overall very happy with purchase of front Anti-Sway bar. Installation required the use of torched heat and a 6 point socket to remove the two front bolts on the original Anti-Sway bar on my 2016 Ford E-450 (Thor Outlaw Class C). After using heat on the frame around the bolts for about 30 seconds, the bolts were easily removed. The new Anti-Sway bar was quite a bit larger than the original and fairly easy to install following supplied instructions. This completes the installation of the front and back Anti-Sway bars and the Loadmaster Reflex Steering Stabilizer. Final test drive tomorrow.


Comments
After a year I did add Sumo Springs and Koni shocks to the front. This completed my front suspension. I will eventually add the Sumo Springs to the rear. Overall very happy with the products I added to my suspension, starting with the Front and rear Anti-Sway bar.

Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars


I recently purchased a 2011 Itasca Cambria 28 with only 10,500 miles. Our first trip made it clear that I needed to stiffen the chassis. Unfortunately Roadmaster Anti-sway bars are backordered, and though you should put those on first, I just installed the Steering Dampener. Easy installation though you need to be careful about seating the bushings. The videos are much better than the printed instructions. Already see a big difference in how much tighter the steering is. Can't wait for the bars to arrive. Disappointed to have to wait 4 weeks.

Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars


This product has performed exceptionally. We experienced extreme winds without significant lane-changing effects on Wyoming highways and very little side to side drift when passed by large trucks. I installed the front sway bar without too much effort but the rear bar was a bit more difficult to install so I had a local Mechanic do the work. I’m very pleased with my purchase.

Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars


Relatively easy installation on my 2004 Ram 3500. It would have been easier if I had removed the spare tire. I only noted a few minor issues. The instructions say to mount the U brackets to the rear two holes in the shock mounts. However, on this truck the shocks mount one in front and one in rear. Therefore, the passenger side mounts in the rear two holes, but the driver side mounts in the front two holes. Otherwise all went well.

Received my 2019 E450 front Roadmaster sway bar yesterday and installed it today. Easy install, Instructions sheets was easy to understand. Did a test drive for 10 miles, Boy what a difference. Feels great , nice and tight , now have front and rear sway bars from Etrailer as well as steering stabilizer . makes my Class C handle much easier going down the road. These sway bars are much thicker than the ford standard bars. Etrailer has great videos to show all installs. Thanks Etrailer for all the info.

  • Recommendations to Reduce Sway and Bounce on 1999 Bounder 28T Ford F-53 Motorhome
    To greatly reduce the bounce and sway you're experiencing with your 1999 Bounder 28T RV I highly recommend a combination of front and rear sway bars along with a steering stabilizer. For the Ford F-53 chassis on your RV that has an 18,000 pound GVWR the Roadmaster Rear Anti-Sway Bar # RM-1139-143 will work perfectly. This 1-1/2" diameter sway bar will actually work in support of the factory bar (the factory unit will not be removed) to provide much better stability on the road. It will...

    I did a little bit of research and it looks like 2006 Fleetwood Bounder with a gas engine was built on a Ford F53 chassis like you mentioned, so the correct rear anti-sway bar for your rig with a GVWR of 20,500-lbs is the Roadmaster # RM-1139-143. It should be noted that the factory u-bolt may not be long enough for the factory nut, washer and 1/2" plate when used with this bar. If that is the case, if you have square top u-bolts will need # RM-590050-00, and if you have round top u-bolts...

  • Comparing Anti-Sway Bars and Axle Stabilizers for an RV on a 2014 Ford F-53 Chassis
    Anti-sway bars and axle stabilizers are similar but they do different things. An anti-sway bar helps more with body roll which is that tilting side to side motion whereas an axle stabilizer helps for with the tail-wag motion. Both are going to make the RV more stable and more pleasant to drive. You can use both but if you wanted to try just one first I would recommend the anti-sway bar.

    According to Tiffin some of their motorhomes are build on the F-53 and the F-59 chassis. If you have a 2015 Ford F-53 chassis you would want the rear sway bar part # RM-1139-143 as that will give you the biggest difference in handling and steering. For a steering stabilizer you would need part # RM-RBK4-RSSA for if your GWVW is less than 26k. If more than that you would need part # RM-RBK22-RSSA. If you have a F-59 chassis we do not have any sway bars or components that would fit.
