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.

  • Best Way to Control Sway on a 2018 Thor Motor Coach Gemini 24TX
    I do have options for you to help control sway on your 2018 Thor Motor Coach Gemini 24TX but they do not make a steering stabilizer for this chassis to my knowledge. Instead, I recommend adding a rear anti-sway bar like the Roadmaster Rear Anti-Sway Bar for Vans part # RM-1209-131. The rear anti-sway bar is actually going to do more for you in regards to sway control compared to a steering stabilizer. The rear anti-sway bars are also typically the most beneficial enhancement that you can...

  • How To Improve the Ride on a 2014 Mercedes-Benz Sprinter 3500 Chassis
    The SumoSprings Maxim Custom Helper Springs like part # SSR-336-47-1 do indeed offer a better ride quality when compared to the SumoSprings Solo Custom Helper Springs like part # SSR-338-47 which is what I assume you are referring to. However, the SumoSprings Maxim Custom Helper Springs will only work for you if you have the standard axle configuration and not the 2" spacer (see photo). If you do have this spacer which most Sprinters do then you will want to consider the Roadmaster Rear...

  • 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...

  • Recommended Rear Anti-Sway Bar For 2013 Mercedes-Benz Sprinter Motorhome
    We do offer rear anti-sway bars for your 2013 Mercedes-Benz Sprinter. If you have a 2500 the rear anti-sway I recommend is part # RM-1209-128. Using this bar helps reduce the effects of crosswinds and shifting cargo or passing vehicles. It attaches to the rear axle and chassis and includes the mounting hardware. If your motorhome is a 3500, the rear anti-sway bar you would need is part # RM-1209-120. I have attached a photo that shows how the anti-sway bar is normally attached on a...

  • Recommended Suspension Upgrades for 2020 Tiffin Wayfarer to Help Fight Sway
    In order to minimize sway on your 2020 Wayfarer Class C, I recommend starting with the Roadmaster # RM-1209-131 since sway begins at the rear of the coach. Adding a rear sway bar is, in most cases, the quickest and most common way to combat sway that is experienced from passing trucks and wind gusts-it's usually the first upgrade that owners go with on the coach. This rear-sway bar has a 1-1/2" diameter and is made from a stronger and thicker steel than the stock 1-3/8" sway bar currently...

  • SumoSprings for a 2019 Thor Quantum KM24 Motorhome
    The correct SumoSprings for your 2019 Thor Quantum KM24 motorhome (on the Sprinter chassis) are the following: Front 500 lb - # SSF-106-40 1,000 lb - # SSF-106-47 Rear 900 lb - # SSR-338-47 1,400 lb - # SSR-338-54 I recommend going with the 1K and 1.4K kits because they will give you more support and I've never heard of someone complaining that SumoSprings have made their ride harsh so you don't have to worry about them being rated too high. I would like to mention one other thing...

  • Installation of Roadmaster Rear Anti-Sway Bar # RM-1209-131 in 2015 Mercedes-Benz Sprinter
    There is no set number of washers that should be left over after installation of the Roadmaster Rear Anti-Sway Bar # RM-1209-131 on your 2015 Mercedes-Benz Sprinter. Roadmaster does not specify this in their instructions since vehicle manufacturing tolerances can vary among production years and even between different vans of the same year. The linked photo shows the installation point for the 9/16-inch washers. You will install one on the outboard side of the end link and as many as needed...

  • Recommended Suspension Enhancement for 2019 Jayco Melbourne on a 2018 Sprinter 3500 Chassis
    The correct Roadmaster anti-sway bar for your 2018 Mercedes-Benz Sprinter 3500 chassis is part # RM-1209-131. This does require some drilling but it also retains (and enhances) your OEM anti-sway bar. You'd actually be pretty surprised at how much adding even just a thicker anti-sway bar can improve the handling of your motorhome. You are definitely looking in the right place when you mention the SumoSprings to help with enhancing your ride as well. I recommend adding SumoSprings # SSR-338-47...

  • Sway Bars & SumoSprings For Reducing Body Roll 2017 Winnebago View 24G On Mercedes Sprinter Chassis
    Adding the additional rear Sway Bar # RM-1209-131 is going to provide you with more stability over just replacing the factory bar with the Sway Bar # RM-1209-120 on your 2017 Winnebago View 24G. Combining both of the bars with the Front # SSF-106-47 and Rear # SSR-338-54 SumoSprings will greatly increase the overall stability of your Winnebago and cut down on the body roll.

  • Rear Stabilizer Recommendation for 2020 Tiffin WayFarer Class C Motorhome Built on Sprinter Chassis
    The biggest improvement you'll make is with a new rear sway bar like the part # RM-1209-131 which is the correct fit for your 2020 Tiffin Wafarer Class C built on a Mercedes Sprinter Chassis. We don't offer a front bar or steering stabilizer but the rear bar will make a huge difference in ride quality and stability.

    For your 2022 Mercedes Sprinter 3500 Class C we have rear sway bars like the Roadmaster part # RM-1209-131 but we do not have any front sway bar options. The rear bars make the biggest improvement in ride quality though so that would be still a really great recommendation I could make.

  • 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...

    The best anti-sway we have for your 2011 Mercedes-Benz Sprinter 3500 chassis is the Roadmaster Rear Anti-Sway Bar part # RM-1209-131.

  • 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.

    I recommend the Roadmaster Rear Anti-Sway Bar, # RM-1209-131 for your 2016 Winnebago Navion Motorhome built on the Mercedes-Benz Sprinter 3500 chassis. This Roadmaster anti-sway bar is made of 4140 chromoly which is considerably harder and stronger than the standard 1020 steel commonly used in OEM installed components. In addition, this has a larger diameter that also increases its torsional roll stiffness along with polyurethane bushings and grommets. We do no have a steering stabilizer...

  • Rear Sway Bar Recommendation for 2015 Mercedes Benz Sprinter Class C Chassis Pleasure Way
    The difference between the two Roadmaster sway bars is the specific 2015 Mercedes Sprinter you have. The part # RM-1209-128 is for the 2500 van and cutaway models but yours is the 3500 Class C model so the rear sway bar is the part # RM-1209-131. At this time there isn't a front sway bar available, but the rear sway bar is the one that makes the biggest difference so the one I recommended would still be a great option to improve your ride quality.

  • 2014 Thor Citation Sprinter 3500 Class C Sway Bar Recommendation
    When it comes to sway bars the biggest thing to consider is the diameter of the bar as that plays the largest factor. However, if the Hellwig you are looking requires you to remove the factory sway bar the Roadmaster would end up having the edge since it allows you to keep the factory sway bar and then provide additional sway bar support via adding an additional one to the setup. Roadmaster is also made of cadmium-plated 4140 chromoly steel and is made in USA.

The Roadmaster Rear Anti-Sway Bar for Vans # RM-1209-120 is a factory sway bar replacement that is 1-3/8 inch diameter. The Roadmaster Rear Anti-Sway Bar for Vans # RM-1209-131 is also an option that fits your vehicle, but this one is 1-1/2 inches diameter and retains the factory sway bar for more stability.

  • Are New Shocks Required When Adding Anti-Sway Bar and SumoSprings To 2013 Mercedes Sprinter 3500?
    As long as the shocks on your 2013 Mercedes-Benz Sprinter 3500 are still in good shape, there is no reason to replace them. However if they are worn out you will notice quite a difference once the replacements are installed. We do not sell shock absorbers for vehicles so I do no have a recommendation on which ones to get, though an OEM replacement would be preferred. If you have not already decided on which sway bar and SumoSprings you plan on ordering I recommend the Roadmaster Rear...
