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.

This was very easy to install.. took about 30 mins by myself! Really was surprised in the difference it made in the handling of my ram 1500. Great purchase

- RM-1129-135

Excellent product, great service from start to finish. This is the anti-sway bar the truck should have had from the factory.

Great customer service. Part fit perfect. Great communication

- RM-1129-135

Just got it today 6-13-22, I would say you need to work on your delivery in a better time.

- RM-1129-135

The sway bar installed quickly and with little problem. It totally controls body roll on this truck. I would have given a higher score except the end links provided in the kit from Roadmaster failed within seven months, or about 6000 miles. I replaced them with Moog. All quiet now.

- RM-1129-135

Very good quality, bushing are heavy duty, except it to do well with a lot.

Quick easy bolt on, major improvement

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 installed the front and rear Anti-sway bars with the steering shock. I am 100% satisfied with the outcome and handling of my RV while driving down the road. I would highly recommend the installation of these items on any RV

You just cant go wrong installing these kits to you RV. Next thing i looking to install is the air suspension kit and new shocks.

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.

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

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.

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

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.

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

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

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.

Been a year now and I will say “it’s the best and first thing you should do to improve the drivability and suspension”. If you motorhome came with stock antisway bars that are small in diameter than the RM then this will make a very big difference in handling on curves and crosswinds, semi trucks.

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

very happy with the product and with Etrailer. Anyone who owns one of these motorhomes realizes it's a step by step process to get it have decent ride characteristics, and adding sway bars and trac bars and steering stabilizers are all part of it in a step by step process. Every little bit helps!

Its all good, its still like driving a saltine box down the road, but it has definite improvement over stock configuration of the f53

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

I recently installed front and rear anti sway bars purchased from e trailor on my 2021 chevy express class c. The order was processed and shipped immediately and arrived within a couple of days. They were easy to install, I was able to do it without help. Although I have not been able to test them thoroughly yet so far they seem to cut back on the bouncing and rolling that was occurring with the OEM parts. I plan to purchase upgraded shocks from e trailor as my next update. —joe

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

The package arrived in a timely manner, just as promised. The installation went as described in the instructions and everything fit well. It improved the handling quite a bit. I already had installed “Sumo Springs” last year (worked great) and the sway bar controlles the sway even more. One thing I can add is, get a long 1/2” drill bit (8” long) to help with drilling the front bracket holes. The drill chuck on my drill, hit the link tabs, causing me to drill at a slight angle (horizontal holes). The biggest problem I encountered is that the bar contacts the exhaust pipe (1/4” gap) and makes noise when driving (see photos) . I have a diesel and the exhaust pipe is about 3” in diameter, which doesn’t help. I’m trying to figure out how to resolve this issue. I will update when I do.

When the anti-sway bar is installed, it is in a set position, but because the exhaust uses rubber isolators that suspend it from the exhaust hangers, the actual position of the exhaust pipe can vary a bit. The good news is that the positioning of the exhaust can be modified a little bit by gently bending the exhaust hangers. If that doesnt work, you can go to a muffler shop and have the exhaust hangers relocated fairly inexpensively.

It should be a factory option. It controls the sway like I hoped it would. No issues one year later.

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

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.

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

This part was absolutely the right pick. I researched a lot of anti-sway products and this one came out on top due to its simple installation (thanks to the etrailer video), price and support from etrailer. It went on just like the video showed, though I had to use an impact wrench for the chassis bolts, the etrailer guy who used a wrench must be a beast. Definitely a DIY project even for novice mechanics. I test drove it and it was hands down the biggest improvement in ride even though I had put on new shocks and have air bags. etrailer is my go-to for nearly everything I do to my RV.

    With how the Firestone Air Helper Springs, like the # F2706, will attach to the frame, you would not be able to install a Timbren # TDR2500D as well. Both of these options will mount in the same place, unfortunately. That being said, the # TDR2500D may be better for your situation than the air bags.
