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 front 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.

Took 6 weeks for Roadmaster to get my anti sway bar order made and sent to me. It fit up okay on our 2003 Fleetwood Discovery MH on a 2002 Freightliner XC chassis, and was easy to install. The combination of this larger sway bar with a blue Saf-T-Plus steering stabilizer made the 38' MH pulling a Tandem Tow HDXL dolly trailer with a Teryx4 SXS and a Buick LeSabre on the dolly, total length 68' so much easier to steer and handle on windy days and with passing semi truck trailer buffeting. Also helped with handling on uneven roadways with ruts and dips. I'm pleased sfter 7,800 miles and 1 year of use with this larger 1 3/4" diameter sway bar compared to the stock bar.

2014 Thor Palazzo Motorhome
Fairly heavy duty compared to stock on my 2014 Palazzo 33.2 Freightliner chassis; appears to be about 5/16” thicker. Install fairly straightforward; I loose fit the U-brackets first (contrary to the directions) then swung it up to the endlinks- this is easier for a one-man operation.
Holding off on 5th star until after test drive with forthcoming steering stabilizer.
So far etrailer has been top notch; very informative relative to order status.

worth every penny, i no longer cringe when semis are approaching.

2018 Freightliner XC-Series
Somewhat thicker and heavier duty than the stock anti-sway bar. Note: the threaded ends of the of the end link rods are longer than stock so after installing, make sure that they do not contact hoses, wires, etc., attached to the frame.

Received the roadmaster swaybar for my Motorhome on time and in excellent condition..
etrailer had the best price available!!
can’t wait to get it installed…

Fleetwood
This heavier duty sway bar for the Freightliner XC XCS chassis when combined with the REAR stabilizer was just the thing my Fleetwood needed.
Prior to this replacement bar (and the rear added bar), the back end of the RV would sway in the most unpleasant way. It was like driving on ICE. You had to watch INTENTLY!
After these bars were installed, body lean was dramatically reduced and the driving on ice feeling was GONE. This much reduced my stress level when driving!

2007 Freightliner XC-Series
The 1 3/4" bar is much stronger and heavier than the stock sway bar. Took longer to get the old bar off than it did to install the new one. The quality of the new bar is far better than the stock one and the mounting hardware and bushings are excellent . Had to reuse the old bolts for the bushing clamps but everything fit fine. Very pleased with the kit and the price was about $100 cheaper through E=trailer. Quick shipping and great customer service. Thanks !!! G

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

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!!

I installed both front and rear Road Master anti sway bars on our last RV and they made a tremendous improvement in handling. It was easy for me to install by myself in my driveway on out Coachman Leprechaun 319MB. I highly recommend this product.
by: Man Bear Pig05/31/2023
This is on a 2004 Dodge 2500 with a 2500 lbs truck camper, Dirt bike on a hitch rack, and 2 mountain bikes on a front rack. The sway bar definitely helps. This one fit well around my stupid 5" exhaust that was installed by the previous owner. The Hellwig would not clear it. I have the Timbren SES and wedges in my leaf springs as well. The sway bar is a nice addition to those items. What I really notice is that when making emergency maneuvers or going off road, the truck corrects quicker than before and feels safer and less likely to tip over. I would not say the bar by itself will solve all of your issues, but couples with other remedies, it will help make your top heavy overloaded ride feel safer. With all my additions, I can confidently go the speed limit and often times well above through the Colorado mountains with no issues.
by: John 11/22/2022
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.
by: George07/13/2023
On my 2021 Mercedes Benz class C Tiffin Wayfarer this rear anti-sway bar fit perfect. I didn’t have to make any modifications to the exhaust. With help I had it installed in 2 hours and 50 minutes. The pictures on the instructions could have been clearer to understand.
by: Richard 10/28/2022
Great addition to my class b rv. Improves handling and stability noticeably, minimal impact on ride quality. Combined with a 1 3/8 front bar the van handles like a sports sedan! Good instructions and relatively easy install, some brackets did not exactly match in my application but were easy to modify.

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.

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.

We ordered the front and rear swaybars and the steering stabilizer for our 22’ motorhome. Unfortunately we weren’t able to install the rear swaybar because of stuff in the way but we did install the front and steering stabilizers. It definitely improved steering a lot. There is less wandering than before and it was just more relaxing to drive. I not sure which component is more responsible for the improvement but I suspect both helped. I only wish we could have installed the rear swaybar as well. Definitely a worthwhile improvement.
by: Robert S.04/27/2023
Installation was straightforward and fairly easy to install. The instructions were clear which helped to get the anti-sway bar installed without any damage or incident during the process. What a difference it makes while driving. Great product.
by: Robert09/18/2023
Great simple installation. Looks great with my Banks Differential Cover. So much more heavy duty than stock. Truck rolls so smooth down the road, like it should. Installation about an hour, worst part was taking the old factory stuff off. Glad I did this improvement! Well worth the $.
by: John 11/22/2022
I was skeptical, but after driving the RV the sway bar made a significant difference. The product greatly reduced body roll when going around curves and turning. It also took the oversteer out of the vehicle. It is a definite improvement over the factory OEM. Well pleased.

view full answer... - Will A Steering Stabilizer Or Anti-Sway Bar Help Correct Play In The Steering Wheel Of A MotorhomeIf you're having lots of play in the steering wheel then a steering stabilizer would be the correct choice over an anti-sway bar, which would be more useful for correcting body sway of the motorhome. For your 2014 Fleetwood Excursion I recommend the Roadmaster Reflex Steering Stabilizer with Mounting Brackets for Class A Motor Homes # RM-RBK18-RSSA. This is going to attach to the tie-rod and help stiffen up the movement for less play. You can still replace the factory front anti-sway...

Sway bar and steering stabilizer make significant difference- drastically reduced does not completely eliminate cross wind drift and rut corrections.
