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.

Lousy because my sway bar is sitting on the floor in the corner of my basement. I ordered the bushing kit and it arrived without the metal straps that secure the bushings to the vehicle. After I contacted your company I was told I had to contact the chevy dealer, who of course, have nothing that fits. Their sway bar is nowhere near the diameter of the one i purchased. I've spent the last year searching swap meets for the items I need. Your product looks like it would be nice, but as it is, it's terrible. It's terrible, your company is terrible and it is highly doubtful I would recommend you to anyone.

Great product. Solved my body roll problem on my lifted Tahoe. I broke the factory one but this one holding up to the abuse quit well.

I can’t believe how well it works!
LT Tire’s and this made a massive difference when towing.

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.

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!

The last thing to upgrade my front suspension on my 2018 Winnebago Aspect 27k. Money well spent! Easy installation, the ride greatly improved. Etrailer shipped this fast and I'm very pleased. Thanks.

Each component was felt the improvement but all together it’s been major improvement & experience

Free from the roller-coaster ride my 2022 thor motorhome had with the factory bars.I have questions about why these companies don't install the suspension while building the rv.

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: Thom03/13/2024
After reading all the information regarding fitment for my 2001 Freightliner Chassis I purchased this rear anti sway bar kit which had a side note stating that if your chassis had different u bolts, which my chassis does I could contact Roadmaster engineering direct for the correct parts. I did contact them directly and they referred me to e trailer, who referred me to Roadmaster, pass the buck game. So after a year I have a half installed anti sway bar kit that is useless and unreturnable because it was half installed waiting for answers that never came. A waste of my time and hard-earned money NOT HAPPY.
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: 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: Lawrence 04/27/2023
Item shipped quickly and the installation was fairly easy in my opinion. Have not been able to drive the RV yet but I'm sure this upgrade will improve the handling.
by: Robert 05/02/2024
The antisway bar was a great investment. Between Etrailer'S videos and the packaged instructions, the installation was straight forward. Great product.
by: Steve 04/26/2024
I installed a front and rear sway bar and they solved the problem. Before that I had a serious problem with cross winds and semis passing. No more white knuckles!
by: Jeff05/10/2024
Front Sway bar by Roadmaster: Great. BUT the provided new bushing that fits in the factory bracket is too thick and needs to be trimmed to fit right. BOTH of these issues SHOULD NOT have to be tolerated by a buyer of what is supposed to be an expensive quality product!!! The staff is superb but they asked me for a PRODUCT review and both brands are not impressive on the hardware.
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: Brian 02/25/2024
As most p30 owners, handling has been an issue. I have had my 1990 motorhome for 24 years and have white knuckled it for most of the time. I have added a trac bar, new rear springs, air bags on the rear. All have had some improvement. I was hesitant about the cost/effectiveness of a new front sway bar. I am here to say that the larger sway bar made a big improvement in handling. I was very concerned about the cost. But glad I pulled the trigger. It handles quite flat and has had some improvement with sway.
by: Greg07/19/2018
I purchased a Roadmaster antisway bar to replace the stock bar on my 2012 Pleasureway Excel Motorhome which is on a Ford E350 chassis. I did the install myself and instructions were very clear and was not too difficult to do. Handling is much improved, I have noticed less body roll when turning or going over bumps. I have included photos to show the difference between the stock bar diameter and the beefier Roadmaster bar.
etrailer shipped promptly and customer service was great.

It really seems like it was tough installation. I would like to help and I have a few questions to ask. Did your 2008 Chevy Suburban have the factory sway bar on it? I know that you would be reusing some of the factory hardware along with the bushings that come with the new sway bar to install it. Is it the factory end links that you need?
