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 A Closer Look at the Roadmaster Rear Anti-Sway Bar-RM77MR

Hi there, I'm Michael with etrailer.com. Today we're gonna take a quick look at this Roadmaster rear anti-sway bar. This anti-sway system attaches to the rear axle and to the chassis. It's gonna use the weight of the axle to brace the frame as it shifts and turns and that sort of thing. So it is going to help minimize your side to side movement for improved sense of overall stability. It's also gonna help diminish the effects of crosswinds, passing motorists, and shifting cargo.

It's going to allow you to execute your turns and quick maneuvers more confidently, and it will allow for a more level ride even on your irregular surfaces. This system is designed to fit the 2019 through 2022 International MV series trucks. It's also going to work with the NeXus motor homes that use the international chassis so the NeXus ghost and the Triumph as well as the Wraith there that you see on the screen. So this is going to work in conjunction with your vehicle's suspension system. It is engineered to avoid interference with most popular aftermarket add-ons and accessories as well.

It is made here in the USA of a one and three quarter inch thick, 4140 chromoly steel. So it is going to provide superior strength. They do use polyurethane bushings instead of the standard rubber variety, so it is going to be much longer lasting for you. The polyurethane is very durable and it resists damage caused by oil, gasoline, and ozone. And so having less wear is going to provide a system that is better supporting your shifting turns and all that to give you a more stability.

Now this does include heavy gauge mounting hardware as well as easy to follow instructions so you can get this installed properly. That also includes some bushing lubricant for you. This is also going to work with your front anti-sway bars. That is sold separately and it's gonna work for certain applications. So if you're wanting to get the absolute most out of your system, I would recommend going with a front anti-sway bar as well, as well as helper springs if you're wanting to have some support for your up and down motion and a steering stabilizer to help with your handling.

This is going to be capable of working with all those additional components if you're wanting to really soup up your ride, give you the most stability and comfort as you're going down the road. This does come with a limited lifetime warranty so if you we're to have any issues with it, you're more than welcome to reach out to us here at etrailer.com. But I think this is gonna be a a great option for you to make sure that you're a lot more stable as you're taking those turns experiencing those crosswinds and that sort of thing. And that completes our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.

  • Recommended Suspension Enhancement For A 2024 Nexus Ghost 33DS Class C Motorhome
    Hi Matt, For a 2024 Nexus Ghost 33DS on an International MV607 chassis you'll need the following components: Anti-Sway Bars: (does not fit models with optional air suspension system) Front # RM67MR Rear # RM77MR Steering Stabilizer # RM46MR We don't currently offer any shock kits that would be a fit with your motorhome but we do offer a few jounce springs from Timbren that can help stabilize and absorb road shock. For the front you'll need part # TMSR001 and for the rear part # TRED001.

  • Front and Rear Sway Bars For a 2019 Nexus Wraith Super C on 2018 International MV607 Chassis
    You will need the Roadmaster Front Anti-Sway Bar # RM-1179-121 and Rear Anti-Sway Bar # RM-1179-110 for your 2019 Nexus Wraith 33w Super C since it rides on a 2018 International MV607 chassis. The Front # RM67MR and Rear # RM77MR sway bars you found fit the newer 2019 International MV chassis. Roadmaster does not currently offer a steering stabilizer for your chassis. And as I see Safe-T-Plus does not have as stabilizer either I believe you will be stuck with the factory unit.

  • Recommended Front Anti-Sway Bar For A 2023 Nexus Wraith Super C Motorhome
    You're looking for the Roadmaster Front Anti-Sway Bar # RM67MR, which is a confirmed fit for your 2022 International MV607 Chassis. As for the shocks, we don't currently carry replacements or enhancements that are compatible with liquid suspension systems. I recommend reaching out to your local dealer or a mechanic shop to find the correct replacements for your motorhome. If you're looking for other enhancements we do offer a rear anti-sway bar # RM77MR and the Roadmaster Exact Center...

  • Recommended Anti-Sway Bars For A 2019 International MV Series Chassis
    For a 2019 International MV Series chassis the Roadmaster Front Anti-Sway Bar # RM-1179-121 would be the correct fit if it was a cutaway/van style. If you had a Class A Motorhome with this style chassis then you would need part # RM67MR. For the rear on the cutaway you would need the Roadmaster Rear Anti-Sway Bar # RM-1179-110, and for the Class A style part # RM77MR

  • Recommended Anti-Sway Bars For A 2023 Nexus Wraith 32W
    Hey Wiley, For your 2023 Nexus Wraith 32W you'll need the Roadmaster Front Anti-Sway Bar # RM67MR and rear # RM77MR. I did reach out to Roadmaster about the compatibility with your LiquidSpring suspension but they haven't seen it yet so they're not quite sure if it would interfere with the mounting of the sway bar. If you take some pictures of the area round the rear differential and show how close the crossmember from the LS suspension sits to the differential they can gauge if it will...
