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.

  • Helper Springs, Steering Stabilizer, and Anti-Sway Bars for RV Built on 2013 Ford F-350 V10 Chassis
    To start I actually recommend Timbren rear helper springs # TFER35092B because they were specifically designed for RVs built on the 2013 Ford E-350 van chassis, have a lifetime warranty, and cost less than the SumoSpring options. They are rated at 3,600 pounds. For a steering stabilizer use the Roadmaster Reflex steering stabilizer # RM-RBK24-RSSC.

    Adding Item # RM-1139-117 on your 2017 E-Series Cutaway motor home may or may not require holes to be drilled in the frame rails for the end links.

Both sway bars working together will provide the best reduction in body roll.

  • Why are There Two 1-1/2 inch Diameter Roadmaster Sway Bars for 2017 Ford E-350 Cutaway
    The reason there are two 1-1/2 inch diameter Roadmaster sway bars that fit your 2017 Ford E-350 is that the # RM-1139-198 is for versions of the vehicle that have automatic snow chains that deploy and the part # RM-1139-117 is for the versions that do not have the chains. So based on whether you have the snow chains is how you'd pick which set to go with!

  • Suspension Enhancement for Motorhome on 1989 Ford E-350 Chassis
    The Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88138 is indeed the correct kit for your 1989 Ford E-350 chassis. The air springs will certainly help to level out the rear of the RV and stabilize the suspension for reduced sway but it's important to keep in mind that this and all other similar kits are designed to work with suspension systems that are in good working order. This simply means that while the springs will provide benefit you likely won't get the chassis up to...

  • Should Front or Rear SumoSprings be Added to 2015 Thor Motor Coach First
    When improving the ride for your 2015 Thor Motor Coach 24C on a Ford E-350 chassis the best thing to do would be to install all of them. The SumoSprings replace factory bump stops and the sway bar replaces your factory sway bar. If you had to choose just one I recommend installing the rear SumoSprings # SSR-130-54 as they will help with both the sway and the jounce as opposed to just sway with the sway bar. Next I would install the front SumoSprings # SSF-106-47 as it will help with the...

For your 2021 Thor Daybreak 22GO on a E-350 chassis you'll need the Roadmaster Exact Center Steering Stabilizer w/ Custom Brackets # RM47MR.
