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.

Very pleased with both the quick service etrailer provided, and also the sway bar. It was at my door in 48 hours! The rear sway went on a GMC 3500HD dually which carries a very heavy truck camper, and it pretty much eliminated sway out of the system. Highly recommend!

Well the sway bar was fine,had to offset just a little 1/4”due to the after market rearend cover.also had to turn axle clamps downwards a little.

Second rear sway bar I've bought for Cevy trucks. Looks like it'll be perfect. Got it installed, because of overhead (arctic fox) camper. Had one before with our old '09 truck, and this is the same application, only newer 3/4 ton truck. Helps with camper sway allot.

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


Easy installs on my 2004 E-450. The new Roadmaster 1139-115 front sway bar and the Roadmaster 1139-147 rear sway bar greatly improved the handling and cornering of the motorhome. I have aDraw-Tite 65001 front mount receiver mounted and there were no problems when installing the front sway bar.


Comments
It is actually a pleasure to drive! When cornering the motorhome would lean and things would slide around and i even had kitchen drawers open. The problems that i had no longer exist. The cost and the work i did to install were well worth it!

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


I think the anti-sway bar is the most noticeable. When I'm turning out of my driveway where there is a dip as I go over the curb-cut, for example, the sway seems limited moreso than before. As for the steering stabilizer, I think the RV seems a little harder to turn at a slow speed, but I don't notice a lot of difference in it's "springing back to straight" as I'm going down the highway. Some of that may be due to the crown of the road. I'm anxious to try it on the interstate to see if it is better there. Well, I drove on a smooth, level Interstate with a tailwind, and it handled like a dream. Bottom line, the biggest difference in driving is the wind and the road surface. These components probably help a little, but I'm not sure it was worth the cost. I'd like to think the RV handles a little better, but I'm not sure that isn't because I want it to after spending the $$$ for these upgrades.

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 .

Installed a Roadmaster 1-1/8" rear sway bar on my 97 Epedition 4wd. Massive improvement. Better steering response, and way less sway. Less fatigue while driving. Crosswinds are hardly noticable now. Very happy customer!

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


This went on our 2019 Windsport 29M. Outside of a couple minor install issues (Breaking frame bolts loose and needing to remove washer on the buttonhead bolt so the shock would fit in) the purchase went great - CS was very helpful the part shipped and arrived quickly. I just finished the test drive and there is a noticeable difference in stiffness I should mention we already had front and rear Sumo springs and Roadmaster steering stabilizer which are a huge improvement over the stock chassis but still wanted to improve the interstate semi push and unexpected wind gusts . So far so good.


Comments
Ive been asked to provide a 1 year update... After the past year I can sincerely say this addition is well worth the price for anyone trying to control roll on class A with F53 chassis. Sumos alone help but adding the rear sway bar makes driving so much more enjoyable.

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.

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.

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.

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


RM-1139-198 is of high quality. Haven’t tested but have installed. Easy install, I was able to reuse the factory bolt holes on anti-sway bar and frame. Which made it fast and easy. Huge difference in size of RM to factory bars. Only issue I had was I ordered kit number RM-1139-198 to fit my 2018 Ford E-350 and this kit was garrantied to fit. But nothing on this product said ONLY if your E-350 or E-450 has auto drop down tire chains, oops I learned this after I received and started install. Part needed is RM-1139-117 which has 11 inch center to center bolt holes on links instead of the shorter 9 inch. The 9” links are just too short to work. I had to order the longer end links and yes they weren’t free. If you watch the install video on either kit number the tech points this out and with the longer links mine bolted up exactly as the video stated. After testing for awhile I’ll review the product again. This is the only improvement I’ve made so far.

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


About a year ago I upgraded the front and rear anti-sway bars on my 2017 26A class C Winnebago on a F450 cutaway chassis. This is the simply the best upgrade to date. It eliminated the body roll and awkward handling in a crosswind as well as the snake like movements experienced when passed by semi trucks. The addition of the Roadmaster anti-sway bars has allowed us to travel 70 to 75 mile per hour on the interstates with confidence and has reduced the fatigue of a long days drive.

Etrailer is by far the BEST place to buy RV parts, period! I didn’t know that they have a price match guarantee, and if it is sold cheaper somewhere else, they will price match it! Tannith saved me hundreds of $$$! Even on an order I placed the month before, because I was not aware of the price match! I can’t say enough about their service, communication and dedication that you are getting the right part for your RV. I will continue to do business with them because they are honest and dependable and provide great updates and communication! Plus you get to talk to a real person when you call in, plus you can understand them!
