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 black powder-coated 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.

Wow, This sway bar is big, heavy, beefy and strong. I saw all the great reviews but was still surprised when I got it. Installation was straight forward but I did have to have a mechanic shop jack the RV up and take the huge bolts of the U-bolts because my impact wrench was not strong enough. I've only put a few mines on it since I installed it but I have already noticed a difference. 679596

I just received the product, which weighs in at "Over 70 pounds" according to the UPS tape attached, and will be returning it unopened once I receive the Return Authorization slip. Please note that this action had to be taken because of "Operator Headspace"on MY PART !!! I failed to properly read the requirements and limitations in their advertisement. The 1139-143 is for a motorhome with the Ford F-53 for an up to a max of 34 foot motorhomes. Mine is a 37 foot and need the one for 18,000 to 24,000 lb. My mistake and the correct one is on the way thanks to the help from the wonderful service personnel at etrailer.com. Great service for less than smart people like me...

Installed on a Tiffin Allegro 31SA by Whited Truck and RV Center in Auburn, Maine. The Roadmaster anti-sway bar and associated parts are rugged and of high quality. Installation time was about 3 hours; drilling the frame to secure brackets took the longest time. This anti-sway bar improved handing and reduced sway, especially on rough secondary roads. 137563

Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars


Good anti-sway bar. Installation was made difficult by being unable to easily remove the OEM anti-sway bar. Although this item was intended to go on a near-new 2015 motorhome, the original retaining bolts were very difficult to remove. However, installation of the RM 1139-140 was relatively easy and completed in about an hour by one person. If two people did the task, it could be done in half that time. The only disappointment, and it was significant, is that there was no mention of torque values for the mounting bolts. 223089

After a year of use over about 8,000 miles, I have to say the improvement they made are moderate at best even considering I put them on the front and back.

Great customer service from purchase to delivery. Kept informed all the way by George with fast shipping. Sway bar was quick and easy to install on my 2018 Windsport, about 1 1/2 hours by myself. Considerably heavier than original, helps reduce sway as advertised. Great experience with company would purchase other items in future. 483047

Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars


RM-1209-131 delivered a day earlier than promised. Installed on 2018 Winnebago 24V View on 2016 Mercedes 3500 sprinter chassis. Good fit had to modify the exhaust which exits on shotgun side ahead of wheels which was to close to the long links. Drove 20 miles to my indoor storage. Quite a reduction to side to side sway. Handles like a different vehicle (better). Can’t WAITE till our next trip. Tulsa auto spring did the installation. Mikes custom muffler shop did the exhaust modification. Do believe l made the right decision not to tackle the job on my own $250 to install. $120 for exhaust modification. In Tulsa, Ok wouldn’t, go anywhere else to get the job done. 715992


Comments
Driven 7500 miles wind trucks and mountains out west. Went from scary ride to more like my f150. Can’t believe Winnebago doesn’t do this at the factory prior to delivery. It would improve their sales probably so much that the cost would be absorbed.

    We have rear sway bars that are a fit for your 2017 Ford F-53 chassis but you cannot use the front bar you have on the rear. If your RV is less than 34 feet long you would want the part # RM-1139-143 or if longer than that part # 1139-144. Typically a rear sway bar makes a larger impact in ride quality improvement than a front one does. We tend to recommend people start with a rear bar since it makes the biggest difference.

  • Products to Improve Steering and Handling of 2015 Tiffin Allegro 32SA
    According to Tiffin some of their motorhomes are build on the F-53 and the F-59 chassis. If you have a 2015 Ford F-53 chassis you would want the rear sway bar part # RM-1139-143 as that will give you the biggest difference in handling and steering. For a steering stabilizer you would need part # RM-RBK4-RSSA for if your GWVW is less than 26k. If more than that you would need part # RM-RBK22-RSSA. If you have a F-59 chassis we do not have any sway bars or components that would fit.
