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.

  • Anti-Sway Bars and SumoSprings for 2015 Forest River Sunseeker 2290S
    Hi Mike; does it actually have E-450 on the motorhome? I'm asking since it is listed online as an E-350. If it is an E-350 you can use the Roadmaster Rear Anti-Sway Bar - 1-5/8" Diameter # RM83ZR and Roadmaster Front Anti-Sway Bar - 1-3/8" Diameter # RM-1139-189. If it is an E-450 you need the # RM-1139-163 for the rear instead. If you have auto chains let me know since that changes which sway bar will fit. For SumoSprings I recommend the SumoSprings Maxim Custom Helper Springs # SSR-106-47-1...

  • Which Roadmaster Rear Anti-Sway Bar for 2009 Fleetwood Tioga 31m Class C on Ford E-450 Chassis
    I have a solution for you, but the Roadmaster # RM-1139-163 is not the correct fit for your 2009 Fleetwood Tioga. Instead, you'll need the # RM-1139-147. I've linked an installation video of this for you to check out, as well.

  • Anti-Sway and Stabilization for 1997 Thor Residency Coach
    Your 1997 Thor Residency chassis is the F-53. The F-450 chassis is found on the Class C Motorhomes but the coaches are the F-53 chassis even with the smaller wheels tucked further under as you stated. I recommend you start with the rear sway bar then the front sway and then the steering stabilizer in order of importance for the most help. The correct parts for your coach specific so you will want: -Roadmaster Rear Anti-Sway Bar # 1139-144 -Roadmaster Polyurethane Bushing Kit for 1-5/8"...

  • Recommended Front and Rear Sway Bar for 2018 Jayco Redhawk 29XK on E450 Super Duty Chassis
    I'll start out by saying that we don't offer Hellwig products, but in my experience Roadmaster parts have a bit more durable components (bushings, etc.) and are generally a bit easier to install; both do a great job once they're installed but the quality of components and ease of installation of Roadmaster parts makes them a bit better in my opinion. It sounds like you're wanting to add front and rear sway bars to your 2018 E-450 Class C Jayco Redhawk 29XK and Roadmaster gives you some...

  • Best Rear Anti-Sway Bar for a 2017 Jayco Greyhawk Motorhome
    Yes, the thicker the anti-sway bar is the more support it will offer thereby decreasing body roll and sway more. I recommend the larger 1-5/8" diameter anti-sway bar for your 2018 Jayco Greyhawk 31FS, the Roadmaster Rear Anti-Sway Bar part # RM-1139-163. The above rear anti-sway bar will be the most beneficial upgrade you can make to your motorhome as this is typically the weakest point from the factory therefore will offer the biggest increase in ride quality.

  • Roadmaster Anti-Sway Bars for 2014 Fleetwood Jamboree Sport 31M
    You are correct, the rear sway bar part number you need for your 2014 Fleetwood Jamboree Sport 31M Ford E450 is the part # RM-1139-163. Then for the front sway bar you'd want the part # RM-1139-189 and you'd be set. These will make a huge improvement in the ride quality of your motorhome so you'll be really happy with them.

  • Which Roadmaster Rear Sway Bar for 2019 Ford E450 Class C Chassis on 2020 Coachmen RV
    I have a solution for you, but the # RM-1139-163 you were looking at is not the correct sway bar, as that one was designed for Emergency vehicles. There is a Roadmaster Rear Anti-Sway Bar that is designed specifically for the V10 Engine and Class C chassis on your 2020 Coachmen with part # RM-1139-147.
