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 called in to ask some questions about a sway bar and reached Paul B. He was precise and professional in describing the answers to all my questions. He confirmed that the item I inquired about was in stock. I ordered the sway bar and Paul confirmed it would be shipped that day.
I received in just a couple days. Thanks E-Trailer!

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


The Roadmaster Anti-Sway Bar is of excellent quality. All of the parts are heavy duty and fit exactly the way they should. I have a 2003 Fleetwood on a Workhorse W22 chassis and considering the age all of the factory bolts and nuts came off without any issues. Installation was easy following the printed instructions and the online video. I really recommend this product.

Very straightforward installation and all the parts were of high quality. This is a substantial, solid sway bar. My RV feels a lot more solid on the road in curves etc. Very satisfied with the product.

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


Was an fairly easy install with two people , has held up well so far . Helped stop sway with my top heavy truck camper load. At the time it was the only sway bar that fit the ram 3500 with 6.4 gas hemi due to exhaust system interference with other brands .

Sway bar has held up well since installation.

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.


Comments
One year later, we have put over 22,000 miles on our rig, and added new tires. The ride is so amazingly better than without the steering stabilizer, and especially the anti sway bars. These additions are absolutely worth the time and money. I would strongly recommend them. You won’t regret it.

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


This is one of the best upgrades I have made to my 2016 F350 dually. The vehicle handles noticeable better while towing as well as without a load. I bought this stabilizer to help with body roll when cornering while towing my 19,000 lb 5th wheel. But I was surprised how well handling improved with an empty truck while driving down winding country roads. My truck now corners better than my wife’s Ford Escape (not exaggerating this). I state this a year after making this upgrade. If and when I buy a new truck, this will be one of the first upgrades I will make.


Comments
Still amazed at how well this anti sway bar improves the handling of my 2016 F350 DRW both while towing and unladen.

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.

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


Last year I installed the Sumo Springs (lighter load rated) front and rear and rear Koni FSD dampeners which helped noticeably on my 2017 Winnebago View 24J by stabilizing the ride.
I finally installed the Roadmaster rear anti sway bar RM 1209-120 immediately after receiving today. Absolutely worth the low cost for the major improvement in ride comfort and stability. These are direct bolt on replacements for the OEM Mercedes part and utilize the stock mounting bracket hardware.
For a total of less than $xxx I have completely transformed the ride of my Class C motorhome.

I’ve been procrastinating for years, I should have donne this modo à long long time ago. What a difference it made on my Kodiak based RV handling. Stop putting it off Do it now, you won’t regret it.


Comments
A year ago we installed a front Sway bar and Davis trueTrack. The combination of these component greatly improved the stability of our Super-C Motorhome. Strongly these components if you have stability issues with your RV.

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


Significant difference when making turns and going around curves. These twin I beam suspension have a tendency to follow uneven road surfaces, this pretty much eliminated a lot of that. Installed it myself with the Roadmaster end links and the only complaint I have is I had to enlarge bolt hole for the end link bolt, other than that, well satisfied. I also installed the rear sway bar at same time, highly recommend replacing the front and rear sway bars together.

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


The sway bar is high quality compared to the oem bar. I have a 2020 MBZ 2500 Sprinter 144. Basically, the roadmaster is three time the factory bar in terms of weight. And it shows. I took it on a ride down some winding roads and sharp turns and the back end feels much stiffer which equals control. I travel alot on Socal freeways to get to my destinations and it was very unnerving when driving next or passing freight trucks. I also pass through valleys and the winds can really making driving a bit uneasy. So, I anticipate this mod will add to my comfort level as well as my passengers. Time will tell. Now for some thing negative, well not quite but still some information buyers will need to know about installation. My van came with endlinks that were not compatible with the roadmaster. I knew this and order a set of end links for a 2019 model. Be aware that you will need new end links if you want to fit this bar to your 2020 model. At least that was the case for me. See pics. Overall, I'm satisfied and the cost is definitely worth the peace of mind.

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


11/2022 we were forced to leave Florida running from Hurricane Nicole. With 25mph cross winds and +15mph gusts our 2016 Vista LX, 31 footer, was a handful to say the least. Without eTrailers sway bars and bump stops we would have not been able to maintain our 50 to 55mph highway speed, better yet we probably would be in a ditch with other RV'S, 5th wheels and 18 wheelers. These items are amazing. I did have installed the Safe T Steer because eTrailer was way behind on their steering stabilizer. Thanks you eTrailer. BTW, if you are in the Indianapolis area I recommend Warner Springs on Bluff Rd. to do your install... Great people.

just took a short trip with my motorhome about 300 miles with new anti-sway bars installed on front and rear axles, totally impressed with ride and handling remove sway from my motorhome about 75 to 80 percent. I would recommend roadmaster's product and your company's knowledge and service, job well done, thank you

Definitely a big difference in the drive! I was expecting longer bolts that hold the sway bar.
