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.

  • Recommended Anti-Sway Bar For A 2021 Mercedes-Benz Sprinter 3500
    If your 2021 Mercedes-Benz Sprinter 3500 is a van then yes, the Roadmaster Rear Anti-Sway Bar # RM43VR is the only compatible option. If your 2021 Mercedes-Benz Sprinter 3500 is a Class C motorhome then you also have the option of the Roadmaster Rear Anti-Sway Bar # RM-1209-131. The real difference between these anti-sway bars and the factory sway bar that came on your Sprinter is the thickness of the bars and the polyurethane bushings, which last longer than the factory rubber bushings....

  • Recommended Suspension Enhancement For 2022 Thor Daybreak On 2022 Mercedes-Benz Sprinter 3500
    I recommend using the SumoSprings Solo Custom Helper Springs for the Front Axle # SSF-106-47 and the Rear Axle # SSR-338-47. These will help improve ride quality by adding additional support to the factory suspension on your 2022 Mercedes-Benz Sprinter 3500 Chassis. Since the springs are progressive they will also help the shocks to reduce road vibration and shock that can cause damage to the components in your 2022 Thor Daybreak. The Roadmaster Rear Anti-Sway Bar # RM-1209-131 is an...

  • Anti-Sway Bars For a 2023 Tiffin Wayfarer 25RW on 2022 Mercedes Sprinter 3500 Chassis
    Based on the information I could find on your 2022 Mercedes Sprinter 3500 cab and chassis it appears to come with a 1-1/2" rear sway bar. The Roadmaster Rear Anti-Sway Bar # RM43VR you found is designed to replace the factory bar but is a stronger steel than the factory unit so it will not flex as much. We do have the Auxiliary Sway Bar # RM-1209-131 which will mount in addition to the factory sway bar and can also be used with Bar # RM43VR above to give you the best reduction in sway.

  • Will Installing A Sway Bar On A 2020 Mercedes-Benz Sprinter 3500 Void The Warranty?
    Installing the Roadmaster Rear Anti-Sway Bar # RM-1209-131 will not void your warranty. Stuff like this is protected under the Magnuson-Moss warranty act. This states that unless the part added actually causes a problem, then installation and use of the part will not void the warranty. That said, the correct sway bar will depend on your vehicle. I see you entered a 2020 Mercedes-Benz Sprinter 3500 and there are two options available for this vehicle. I have both listed below. Cargo Van...

  • Anti-Sway Bars for 2020 Sprinter 3500
    I reached out to my contact at Roadmaster regarding your 2020 Sprinter 3500 and he said they only carry a replacement # RM43VR Rear Anti-Sway Bar. Since this is replacing the factory anti-sway bar with a thicker and more rigid bar, it is hard to imagine it causing a problem since it goes in the same location. They do not make anything for front anti-sway or a steering stabilizer. I hope this information is helpful.
