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.

Video Transcript for In-Depth Review of the Roadmaster Rear Anti-Sway Bar-RM84ZR

Hi there, I'm Michael with etrailer.com. Today, we're gonna take a quick look at this Roadmaster Rear Anti-Sway Bar. This is an anti-sway system that's going to mount to your rear axle and to the frame of your vehicle. This is going to help to minimize your side-to-side movements. So it's going to improve your overall stability of your vehicle. It's gonna diminish the effects of your crosswinds, your passing motorists, or giving your shifting cargo to help minimize the effort required to keep your vehicle in line.

So it is gonna help reduce driver fatigue and make it much easier for you as you're going down the road. This will allow for a level ride. Even if you are going over irregular surfaces, potholes in the road and that sort of thing, it's gonna make sure that you're staying nice and level. It's also going to help it make it much easier for you to execute your turns and quick maneuvers with confidence. You're not gonna feel that massive body roll like you normally would.

So this is designed specifically for the 2020 through 2021 Dynamax DX3 and Force HD motorhome with the Class C 8,000-pound axle, as well as the 2018 through 2021 Freightliner M2 with the Class C 8,000-pound axle, and the 2020 Newmar Super Star and Supreme Aire motorhome with the Class C 8,000-pound axle. So if you have any of those vehicles, this is designed to work for you. This is going to work in conjunction with your vehicle's suspension system. It's engineered to avoid interference with most popular aftermarket add-ons and accessories. So if you are gonna be adding multiple components, this will still work for most situations.

This is constructed of an inch and three-quarter inch thick 4140 chrome alloy steel. So it is gonna be very, very strong. We also have polyurethane bushings instead of the standard rubber variety, so it is going to be a much longer lasting system. It's gonna hold up better for you. The polyurethane is durable and resistant to damage caused by oil, gasoline, and ozone.

And less wear is obviously gonna mean it's gonna give your system better support. There's gonna be less give, so is gonna do a good job for you. This kit is also going to include all the heavy-duty, heavy-gauge mounting hardware, easy to follow instructions, and some bushing lubricant so that you can get everything lubricated properly. This will also work with front anti-sway bars that are sold separately, depending on your application. Not all applications will accept those, but if you want to add even more stability, some applications you can add on that front anti-sway bar. But this kit is made here in the USA, so you can trust it is gonna be made to the high quality standards that we've come to know and trust for products that are made here in the U.S. And it does also come with a limited-lifetime warranty. So if you we're to have any problems with it, you're more than welcome to reach out to us here at etrailer.com. We're always happy to work with our customers to make sure you're getting good quality products and having a good experience. So that's gonna conclude our look for today. Again, I'm Michael with etrailer.com. Thanks for watching..
