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. For a front anti-sway bar you can use # RM-1139-176 which will replace the factory sway bar. And for the rear you can use # RM-1139-117....

This is confirmed to fit this chassis and it will do a great job of minimizing sway and driver fatigue by improving stability and drivability of the RV. It will mount to the rear axle and frame with the included hardware. For a front sway bar you can...

    I recommend starting with the Roadmaster Rear Anti-Sway Bar, # RM-1139-147. This will reduce side-to-side movement for a noticeable improvement in your vehicle's stability and reduced body roll. For the front, I recommend the Timbren Front Suspension Enhancement System, # TFEF350.

Once the folds are compacted, the stacked barrel...

  • 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...

  • Suspension Upgrades Available to Prevent 2014 Ford E350 Van From Wandering In Lane
    As long as your E-350 van doesn't have the OEM steering dampener installed, you'd use the Roadmaster # RM-RBK2-RSSC you'd looked at. The two best investments in the handling issues with the long wheelbase Ford E-Series vans is installing a steering stabilizer and a rear anti-sway bar. The steering stabilizer is where I recommend folks start, because the majority of the time the steering stabilizer does the trick but if it doesn't completely solve the wandering issue the addition of an...
