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.
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.

2018 Chevy Express 3500 Cutaway box truck with a liftgate, swayed horribly. With this installed, she's rock solid.
by: Tom H.09/27/2020
Dramatically improved the cross-wind stability when combined with front bar. Big investment in Material and Installation labor on both bars ~ $1800. Local shop charged $250 to install the front. A RV center installed the rear for $400.
Roadtrek Popular 210 on Michelin Tires handles stunningly well for a 9000 pound gross weight vehicle. Also mounted upgraded shocks all around and replaced deteriorated bump stops on front.
Replaced front sway bar attachment links with Chevrolet OEM for $85 for the set of two.
B-class Built on Chevrolet 3500 Express Cargo Long Chassis by RoadTrek Canada.

After installing this front and rear sway bar my RV, it handled much better when in windy conditions and being passed by large trucks. The front sway bar install was very easy. The rear sway bar was much tougher and ultimately I had to have Camping World install that one. It took them about an hour and half to install just the rear sway bar. This was installed on a 2014 Chevy express 4500 frame.

Nice product. But Hardware was missing and I had to go buy parts. Is a bit more work to install than you would think. Also the directions are terrible, better hope you can visualize. I did by myself but sure would be easier with 2 people. Took me 3 1/2 hours

by: Larry M.03/03/2023
I have a 2017 Ford F350 Super Duty SRW, and we haul a heavy truck camper (Lance 1055.) I have Stable Load Uppers and HD airbags, but wanted to add a sway bar to add that extra layer of control, even though my truck has handled the camper well over the last 2 years and 10,000 miles. My truck did not come with an OEM sway bar installed, so I needed this kit that included the End Links too.
The Roadmaster Rear Sway Bar and End Links sold on etrailer are top quality products. They are robust and well made, with quality hardware to match. The product deserves a 5-star, and even unloaded, my truck handling improved right after installation, with improved cornering and no real impact on ride quality in my opinion. I have not yet loaded up our camper or towed our boat, but I have no doubt this sway bar will substantially reduce sway and will improve control and handling when the camper is loaded.
So why 4 stars and not 5?
1. I researched this product and the installation in detail. I planned on installing it myself and expected to find plenty of detail on etrailer's site, or Roadmaster's site, or the internet. My most pressing question was about where to mount the end links, and the orientation of the sway bar arms since I wouldn't be using the OEM end links. That information was no where to be found on the etrailer site, Roadmaster's site, or in any installation manuals. For a product and supplier that has likely sold lots of these to Ford Super Duty owners, I was surprised to find how little info was out there. The installation video on the etrailer site was helpful, but did not include any information for the end links, as they had a 2015 Super Duty and used the OEM end links already installed. I contacted etrailer and they told me to contact Roadmaster for more info on where to locate the end links with this kit.
2. I contacted Roadmaster. They told me they had no instructions and that despite my truck already having the cut-outs for the OEM bracket that attaches the OEM end links to the frame, that none of those holes may work for me. So they suggested I connect the sway bar brackets to the axle first and then see where the arms would line up with the end links. The tech also suggested that it wasn't critical that the end links were perpendicular
to the frame, but that I should try install the end links to allow the arm of the sway bar to hand as close to parallel as possible. No bueno. When I installed this the 14" end links (center hole to center hole) didn't allow for the arms to hang parallel to the frame. And I don't think it matters as the orientation of my sway bar and the arms looks about like every video or picture I could find on the internet of this year/model truck and this sway bar kit. It seems to function fine.
3. Installing it was a bear, especially the way they instructed me to. And I had to make some modifications to fit my truck, as the sway bar arms were rubbing up against my airbag mounting brackets. I got it installed, but the thin instructions turned what should have been a 60 minute job into 2 1/2 hours. A bit frustrating.
All in all, this will do the job intended and will provide me with peace of mind next time we load our camper. I am a bit frustrated that there were zero installation instructions specific to my year/make/model of truck given it did not have an OEM sway bar and the end links had to be installed with a bit of guesswork. You will also note in my pictures that I had to mount the end links to the sway bar arms differently on each side to make the bar fit around my air bag mounts.
by: Terry04/02/2023
Fairly easy install. Drilling the hole in the frame was decent started with a 17/64 pilot hole then the 17/32 final hole. Take your time and let the drill do the work.
Do be aware of the hole placement on the drivers side as there are brake lines and wiring there.
by: Neal02/09/2023
This product arrived on time, and is as described in company literature. I have installed the sway bars and the sumo springs on my 2019 Ford E3 26 foot Thor motorhome. Installation is fairly straightforward. Having said that, I am a retired farmer and I am quite familiar with this type of work. Having the proper tools makes the job go much quicker and easier. Installation of the front sway bar took a little under an hour. The rear sway bar is a bit more complicated to install, but he can be easily accomplished by someone of average mechanical skills, equipped with the proper tools. I strongly recommend removing the rear wheels to facilitate installation of the springs and the sway bar. I have not driven my motorhome yet, but will be taking an extended trip in March. I am looking forward to an improved ride.

OH My! If you are thinking about getting one for your P32 wide body. Please don’t hesitate. It REALLY Works. Take the white knuckle effect out of driving. EASY installation! Easy Ordering from etrailer. Roger helped me get through the buying process and shipped to my house in 2 days! Thank You!!

This sway bar is the real deal. Easy to follow instructions but I had it installed because I'm lazy. It took one hour labor

Replaced the anti-sway bar on our 2019 F350. No special tools or jacks needed for the installation. Now our Lance 850 truck camper doesn’t sway nearly as much as before. Big improvement. Very pleased!

- Anti-Sway Bar Recommendations for a 2008 Chevy Express 3500 MotorhomeFor the front and rear anti-sway bars that fit your 2008 Chevy Express 3500 Cutaway Chassis you will need the following: Front - # RM-1109-149 Rear - # RM-1109-175
view full answer... - Troubleshooting Noise Coming From the Rear of Vehicle When Turning CornersSounds like the bushings that connect the sway bar to the vehicle's frame may be worn out. With the bushing worn out there will be extra slop and movement in the connection causing the noise when making your turns. I recommend replacing the sway bar and bushings. With worn out bushings, the bar may have started to wear on the busing ends and just replacing bushings may only put a band aid on the problem. Our sway bars from Roadmaster come compete with new bushings and all the hardware...
view full answer... - Suspension Enhancement Recommendation for a 2007 Chevy Express Van to Fight Death Wobble.I spoke to my contact at Roadmaster and he informed me that to combat your death wobble they recommend you first start with a rear anti-sway bar like the Roadmaster Rear Anti-Sway Bar # RM-1109-175. He said that should fix your problem, but if not you next would want to get a Roadmaster Reflex Steering Stabilizer # RM-RBK17-RSSC that you referenced. My contact at Roadmaster did not recommend removing the coil either.
view full answer... - Could Roadmaster Sway Bar # RM-1109-175 Fit 2015 Roadtrek 190 with GeneratorAs long as the generator allowed the stock sway bar of your 2015 Roadtrek 190 the Roadmaster Sway Bar part # RM-1109-175 would also fit. I looked up pictures and it looks like there shouldn't be a problem as I was able to see the generator and the sway bar both fit at the same time.
view full answer... - Sway Bar Options For 2018 Chevy Express VanFor your 2018 Chevy Express Van 4500 you have both a front # RM-1109-149 and a rear # RM-1109-173 sway bar option. For the rear sway bar take a look to see what set up you currently have and choose between # RM-1109-173 or # RM-1109-175 to match what you have. Dave does a great job explaining the benefits and goes over the installation of the front sway bar so be sure to check out the video I've included for you!

The axle mounting kit (which is included with this part number) is indeed to allow for an attachment point and base on the axle. My contact did say that if the chassis was built before 6/2006 the kit should be needed. Take a look at the installation video I attached so you can see exactly how the bracket kit is used. If you can send...

The correct part number for the rear bar is the following: - Roadmaster Rear Anti-Sway Bar # RM-1109-175 A rear anti-sway bar like # RM-1109-175 is the best way to enhance the ride of your motorhome because it acts as a brace between the frame of your motorhome, and is constructed...
view full answer... - Rear Sway Bar Recommendation for a 2014 Forest River Sunseeker on a Class C Chevy 4500 ChassisYes, for your 2014 Forest River Sunseeker built on a 4500 Class C Chevy Chassis you would want the rear sway bar part # RM-1109-175. This is a 1-1/2 inch thick sway bar confirmed to fit your vehicle. The part # RM-1109-150 will also fit your RV but since it's a slightly thinner bar it wouldn't offer as much stability. The trade off between thinner vs. thicker is that thicker is more stable but may cause a slightly harsher ride if the vehicle is on the lighter side. For the size of your...

For instance, if you have the 2500/3500 Class C Cutaway you can use part # RM-1109-175. This also fits other versions such as the 2500/3500 Class C Van. Unless the OEM exhaust has been modified to allow installation of Thor RV components you should have no issue installing this on your RV. You can check with Thor using your VIN to confirm which base chassis you have and then...

I've attached an installation video to assist, but it does not have the generator in that location. I also recommend the front sway bar # RM-1109-149 which is also confirmed to fit.

view full answer... - Rear Anti-Sway Bar for Class C RV Built on a 2001 Chevy 3500 Express Van ChassisIt is most likely a Class C. For a rear anti-sway bar you would use # RM-1109-150. Since it is a 2001 Chevy 3500 chassis you will need an additional axle mounting bracket, # RM-590061-00, to complete the installation. I have included a link to the sway bar instructions for you. If it is rated as a Class B there are no confirmed fits listed.

Basically if the root cause is not addressed there is no guarantee that a steering stabilizer or other product would solve the problem.

view full answer... - Rear Sway Bar for Small School Bus on 2002 Chevy Express 3500 Cut-Away ChassisI spoke with my engineering contact at Roadmaster, who tells me that the # RM-1109-175 anti-sway bar is the correct choice for your Micro Bird Bus on a 2005 Chevy Express cutaway chassis. Because the vehicle was built before 2007, the # RM-590061-00 mounting kit will be needed.
view full answer... - Anti-Sway Bar for a 2002 Chevy 3500 Cutaway RVThere are several items to reduce sway, see link, that will fit your 2002 Chevy Cutaway 3500. If the existing bar has a 1-1/2 inch diameter then you can use # RM-1109-175 that you have referenced. If the chassis was built before June 2007, you will also need bracket kit # RM-590061-00. If the existing bar has a 1-3/8 inch diameter then you would use # RM-1109-150 and the same bracket kit listed above # RM-590061-00 for chassis built before June 2007.
