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 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.

I purchased this part because of the rocking on my 2011 Tiifen 34TGA built on the Ford F53 frame. After searching I found this on etrailer and I have to say the video and customer support from etrailer is outstanding. The part came quickly. The install is straight forward as the video shows but be prepared for some hard work. Getting the bolts off the frame after years on the road requires a lot of muscle, my 12 gal compressor and Harbor Freight air wrench was not upto the task. You will need a torque wrench that goes upto the 300 ft/lbs required for the plate install. We had to use our legs to get to 300.
After installing I took a long test drive and the difference in handling is amazing. Much less rocking and more stable. I would recommend this anti-sway bar to anyone with this Ford frame.

After a year of use the product is still rock solid and keeping my unit from rockin and rollin on the highway and local roads. I still recommend this for your MH on a the Ford F53 chassis.

I have not been able to get it installed, it is too difficult for my me to do in drive way, the front was easier. I have however installed the front anti sway bar and Roadmaster stabilizer. very happy with handling improvement

Here is an installation video that will give you a visual on the install of your 2016 Ford F-53 to help you out starting at the 6:10 mark:

2018 Fleetwood Bounder Motorhome

This was the right product to start with. Stopped the rolling. Handles so much better in cornering. Trucks don’t seem to push me as much now. Just installed Koni shocks and will see how they do next trip


I purchased the Roadmaster rear anti-sway bar to help improve sway and cornering on my 2013 Fleetwood bounder 35K class A. Motor home. While towing my 26 ft enclosed trailer. It made a great improvement and would highly recommend it.


The package arrived on time and everything was as advertised. I installed it the next day, doing it solo it took a little a little longer as the parts are heavy.


I called to try and buy every upgrade I could to improve the handling of my 35’ class A Tiffin. I wanted to buy front and rear sway bars and a steering stabilizer. The rep wouldn’t sell me all of those. Said he would only sell me the rear, and to give that a try till before buying anything else. He was right. Took care of all my issue with handling. The rig handle perfect now. I can cruise the highway with one hand while towing my Jeep behind the RV


The kit had everything needed. I made the factory U-bolts work on my 24K pound chassis. I recommend ordering the extended bolts on these spring brackets.
Made a major difference on stability and handling on the road.

2018 Ford F-53

Purchased Roadmaster front & rear anti-sway Bar and a Reflex steering stabilizer for a 2019 Winnebago Vista 27N. Heidi, customer representative, was extremely helpful assisting me with the order. Products were delivered in three days. The difference in which the RV rides with anti-sway bars and stabilizer installed is incredible. Much smoother ride with very little rocking. The RV is a lot easier to control when taking a turn. High winds and passing 18 wheelers are no longer an issue. The RV stays on course with very little effort on my part. Highly recommend these products for any RV no matter the size and a shot out to for their outstanding customer support attitude.


Product is definitely quality built.
to install as our unit is currently in winter storage. Can’t wait to install and try out!


The Ford chassis is crappy for riding in a motor home. The sway and rock will make you absolutely seasick going down the road. I bought this sway bar, read the directions, watched a you tube video,and I installed it myself. The ride now is like a high dollar motor coach. Makes all the difference in the world.


The added stability makes my motorhome a pleasure to drive any most road conditions. Mountains, cross winds narrow back roads. Really a nice improvement.


I have not opened my package, but want to compliment, or Arthur, on the excellent job he did helping me. He knew his product and was willing to take the extra time and explain it all to me.


Roger at etrailer is THE MAN!! I called him because I needed to improve the ride & handling of my RV because she would sway all over the road, especially at highway speeds. Any tractor trailer would suck us into its 'air wake' when passing us. Roger offered me the options of heavy duty front & rear sway bars....heavy duty steering stabilizer....and Sumo Springs front & rear. WOW!! What an incredible difference!! The Coach 'rides on rails' now!! Highly recommend this company & Roger's expertise to anyone reading this!!


After installing Sumo springs, Bilstein shocks and steering stabilizer I still felt there was more I could do. I installed the Roadmaster Rear Anti-Sway Bar. The result of adding this last upgrade of the suspension was icing on the cake. My coach now drives as good as my last RV which was a diesel pusher. I believe all of the upgrades came from etrailer. 2012 Tiffin Allegro Ford F53 chassis


Combo of front / rear sway bars and steering stabilizer
Made a huge difference on Class A MH from winds and uneven


Again improved the handling of our motorhome and made driving less tiresome. The videos provided made the install very straightforward.


Made highway driving more safe.


Competitive pricing and prompt delivery.




Amazing difference!! Videos walked me through the installation and it went very well. The ride is incredibly better!!

2015 Kia Rio

I'm reviewing service and install only. It's January and I'm wintering in our 2015 Winnie Vista 35F in Rio Grande Valley, TX. We are not driving again until April. Then we can judge the result. For now, we are taking advantage of the concrete pad and electricity at the RV park to install :-)
I installed by myself and it took about 3 hours with impact wrench, ratchet, Crescent wrench, etc. Original order with [another website] came with missing parts. Returned and called etrailer. Spoke with Shawnee and she answered all questions. Packaged arrived with all parts. etrailer videos show step by step and are current/updated too. I called as I was completing the successful intall, this time taked to Ed W and ordered the front Roadmaster anti-sway bar and front Sumo Springs too. They will arrive in a few days and I hope to install both in a day. Same detailed videos available by etrailer for each of these items too. Looking forward to the 1,200 mile trip to Iowa as a test drive in the spring.


Prior to installation of this kit my RV acted like it was going to tip over as it swayed from side to side when I made a turn or was hit by a cross-wind. Post install the drivability of my 37' RV increased by 100%.


Great prpduct..made a big difference in the handling of my motor home

2017 Fleetwood Bounder Motorhome

The Roadmaster products are great. They fit as advertised and etrailer's videos are very helpful for installing. I would recommend you supply the grease in a small tube or other container. Both of my sway bar hardware kits had grease smeared all over the inside as the plastic grease container was crushed.
I would highly recommend suggesting or requiring the inclusion of new U-Bolts when buying the rear sway bar or steering stabilizer. My Fleetwood Bounder started its life in Ohio before I brought it to California, and unfortunately there's considerable rust on the suspension components. Removing the U-Bolts was extremely difficult (applied rust penetrant and heat to break the nuts loose). I'm contemplating replacing the U-Bolts to ensure their structural integrity.

2012 Ford F-53

Service is excellent. All of the parts were shipped and the installation video was right on. Great product! Made a huge difference in our initial test drive on our 2012 Tiffin Allegro.
