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.

I have no more sway on our 2005 Fleetwood Southwind Class A after installing this sway bar. However, I must be honest, When I went to install this sway bar, I found that both of the bushings and one of the brackets that attached the factory sway bar to the chassis were completely missing. I replaced the bushings and bracket at the same time that I installed this Roadmaster HD sway bar. I can't honestly tell whish fix or the combination made the difference.

I ordered the sway bar on Thursday 8/15/2013 and received it on Thursday 8/22. That was very quick shipping for something as heavy as the kit. Price was the lowest I could find on the net. The list price is $980.00 found some places charge around $100.00 less then list plus shipping. Saved a lot by buying from etrailer.com. What surprised me was that etrailer.com was able to ship it right away, when I talked to Roadmaster they said the kit was out of stock and would be two to three week before it would be shipped, was told the samething by other's I checked with. Good experience shopping at etreailer.com, will be back.

I purchased a 2000 Itasca 35U on the Ford Chassis last fall. On the 250 mile drive home on the Coquihalla Hwy in BC Canada ( highway thru hell ) I was white knuckled and afraid this was not ever going to be enjoyable or safe drive.
Did I waste my money? No.
With a little research I found what I hoped would save my dream of hitting the road in this motor home. I found etrailer on line and they had everything I wanted and at the best price I could find anywhere.
I purchased the Roadmaster Front and Rear Anti-Sway bars for this Ford chassis and replaced all four shocks.
The " Roadmaster Products" transformed the drive better than I could expect or ask for. It feels safe and solid on the road! I am so thankfull.
etrailer earned my business and trust. If you are looking to feel safer and more in control in your motorhome, buy this package! I deserved to enjoy a safe and stress free ride and so do you.
In conclusion, etrailer and their Roadmaster products are a must for this motorhome.

I bought this kit with the intention of installing myself, but a quick review of the instructions convinced me to take it in to a shop instead. The installation is not particularly difficult, but was facilitated by some tools that I simply didn't have. In particular, you'll need a BIG torque wrench to retorque the U-bolts, and on a lesser difficulty level, you'll need a very compact drill and stubby bit to install the frame brackets. I could not get a straight path to the correct location with my drill. It took the shop less than an hour, and was probably much simpler for them since they could put the vehicle on a lift. Otherwise, no surprises. The install could be completed by a home mechanic, but would require at least one somewhat specialized tool - a torque wrench rated to around 400 ft-lbs. The Roadmaster instructions suggest reusing the old U-bolts if they are long enough. I called a different source for new U-bolts, and the tech there suggested that, whether the old bolts fit or not, I should probably purchase new bolts. Apparently suspension U-bolts are threaded in such a manner that they are not intended to be reused. News to me.

What a complete difference this made on my Class A motorhome. At highway speed, I am no longer pushed aside by the big rigs. The coach tracks straight a whole lot better, and body roll is improved. Installed it myself, with help from a buddy? Highly recommend this sway bar!
This is my second purchase from etrailer. Both flawless, with quick shipping.

Easy to install, but of questionable value. Reduction in sway was perceptible, but in the end it resulted in only modest improvement.

I bought both front and rear anti-sway bars for my 2015 Forest River Georgetown 364. After over 10K miles, I still say the improvement is only modest. It wasnt until adding Sumo Springs that I saw a significant improvement.

I installed the 1-3/4" sway bar kit. I have a 38' coach so wanted all the help I could get. Thus far the improvements to the handling have been very very welcomed. It's now a rarity that that I encounter any sway or push from passing trucks and barely noticeable sway from strong crosswinds. Now I don.t have to fight the coach constantly. Driving is much more relaxed.

Bought this a year ago. Arrived promptly. Installed with no real problems. I had to get a larger torque wrench to get the bolts tightened to specs. 5000 miles later, I have really enjoyed the improved handling. I also installed the front sway bar. I would highly recommend this to anyone.

Good price , got it fast that = happy customer . The sway control was easy to install drilling the frame takes a good sharp drill bit . The only problem I had was when I install the bar I install it upside down witch make it hit . When I called RoadMaster after a bit they told me to flip the bar over . I told them in the instructions they only say to install bar , no this side up or this side down so I put it with the RoadMaster name up . He said there was a running joke if the label was down it probably was rite . NO JOKE TO ME .

Great service. Shipped UPS 3 days. Arrived yesterday. Some of the packaging could be better, but overall I'm very happy. Haven't installed yet, I'll post some pictures of them later. Hopefully they will improve the ride/driving in my F53 chassis motorhome as much as Roadmaster claims.

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.

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.

This bar will not only outperform the stock bars on RVs but will also last longer. Check to ensure there is enough factory u-bolt available to accommodate the factory nut, washer and 1/2" plate.

Typically a rear sway bar makes a larger impact in ride quality improvement than a front one does. We tend to recommend people start with a rear bar since it makes the biggest difference.

view full answer... - Rear Anti-Sway Bar for 2011 Georgetown 360 Motorhome on a Ford F-53 V10 Chassis and 22K GVWRThe correct rear anti-sway bar for the 2011 Ford F-53 motorhome chassis V10 rated for 22,000 pounds is # RM-1139-149. Check to ensure there is enough factory u-bolt available to accommodate the factory nut, washer and 1/2" plate. If the u-bolts are not long enough, the # RM-590050-00 u-bolt replacement kit is needed; sold separately. I have linked a video showing an example installation for you.

I attached install videos for you to check out as well. I am not sure which Blue Ox sway bars you tried to install, but these two will fit and work well.

Typically the product that makes the biggest difference in body roll, handling, stability etc. is the rear sway bar, then the front sway bar, and finally the steering stabilizer. Suspension enhancement does help too but I wouldn't put it quite in the same category as the other products.
