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.

2015 GMC Sierra 3500

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



After one year I can tell you all that this sway bar really helps in windy conditions with my Wolf Creek 890 on the bed. Less lean and easier to counter the gusts of wind you get when passing large trucks.

2019 GMC Sierra 2500

Product arrived in a timely fashion. It works as noted on the website.


Good product



Great product

Volkswagen CC

The Roadmaster was easy to put on and works good, At this time I have a large Truck Camper (Lance 1172) on my GMC 3500HD DRW CC right now, but in spring I will be towing our a 43ft Voltage Toy Hauler.


Works well. Knocked out 50% sway going over a curb and helps considerably on the highway during high wind.

2011 Chevrolet Silverado

This ant-sway bar has changed the ride and the handling of the truck I wish I had got one sooner..


Very pleased with both the quick service etrailer provided, and also the sway bar. It was at my door in 48 hours! The rear sway went on a GMC 3500HD dually which carries a very heavy truck camper, and it pretty much eliminated sway out of the system. Highly recommend!

2019 GMC Sierra 2500

Second rear sway bar I've bought for Cevy trucks. Looks like it'll be perfect. Got it installed, because of overhead (arctic fox) camper. Had one before with our old '09 truck, and this is the same application, only newer 3/4 ton truck. Helps with camper sway allot.


Well the sway bar was fine,had to offset just a little 1/4”due to the after market rearend cover.also had to turn axle clamps downwards a little.

2014 Chevy Silverado

does very well work but they lacked some parts in the box and there were parts that were unrelated

Silverado 2014 2500HD long box


Great product . Makes my pickup with 9' camper ride great . Corners like there isn't a camper on .


Best decision in a long time


Great product, really can tell the diff erence


great is a good day project










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.
