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 front 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.

2007 Volvo Cross Country

I have a 2007 Winnebago Voyage 33V workhorse frame . I spent a lot of money trying to get this RV to handle correctly. I thought that the Workhorse frame had little sway to it and concentrated efforts to track bars front and rear and new steering box and a steering damper but had little improvement. My last effort was sway bars, front and rear and WOW what a difference!!! I ordered from E Trailer and to my surprise on day two it was sitting at my front door. Instructions were easy to understand and install wasnt difficult, took a couple of hours to put both on. I drove yesterday pulling a 27ft enclosed trailer in winds of 25 mph with gusts to 50 and was "Blown Away" by how stable the RV was after installing these sway bars. Easy one handed driving in the worst of conditions. I now am finally happy with my RV and look forward to next years cross country trip. Thanks E Trailer, I have bought several products and always appreciate the quick delivery and your follow up email to see if everything went well, its rare today to have your level of support. 443464

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


Comments
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

Sway bars are still working great. Would not have another RV without them.

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


I put this on my 2015 Winnebago view. I left the stock swaybar and added this one to the front of the rear axle. It was the single biggest improvement that I did to the suspension. I can't believe Winnebago sells the RV without this upgrade. It improves handling in the wind or turning corners tremendously. 258934

I just installed the roadmasteranti sway bar 1209-131 on my 2013 Winnebago via.The vehicle is a 2012. it fit well and road test good. I had to shorten the exhaust about 9 inches because it interfered with drivers side arm other than that its good to go. 108043

I am thinking about adding the 1209-131 to my 2011 Winnebago Via 25Q. Which model Via do you have? Im hoping I wont have to modify the exhaust on my Via Q. Thanks.

I put the sway bar on a 2012 25t I did shorten the exhaust about 9 inches I think 2 or 3 inches would have been good. That was easy to do, as new as they are just take exhaust loose at first coupling pass the elbow slide it out and take some off the piece that goes to the inside. Worked well for me. Going from our drive onto the blacktop road in front of our place was all it tuck to decide it was worth the effort. It fit very well. Thanks Mack. PS I am 75 and 240 Made a man door step for drivers door .It works well Love it. Mack

I have a 2000 dodge van 3500. Roadtrek versatile. The installation of Sway bar 1129-111 was somewhat easy. Except for connection to the Fram rails. Vinyl cover on driver side fram rail and propane lines next to rail on both sides. It would make installation Easter to remove rear tires and support vehicle on Jack stands on level ground. After driving for several miles the sway bar performed well. Would recommend rear sway bar to help stabilize your vehicle. Thank you 386045

Very well constructed fit and finish are top of the line. I have not tried this yet because I need a 21mm crows foot wrench for my torque wrench(200 ft-lb) for the cross tube bolts. I am hoping that it will minimize fishtailing from our tow car, as well as controlling sway. 398602

It took a little effort on the phone to figure out which sway bar was needed for the motorhome I have. I was skeptical about the right one being sent but it was correct and installation was a couple of hours. It fit perfectly and really dampened the body roll we were having. Worked great, service and delivery was fantastic. This was the first time I have used etrailer.com and am very happy with their product and willingness to help. I'll be using them again and I highly recommend them. 356110

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


This is the first of three pieces I wanted to install on my Rig. (budget permitting) The advice to start with this rear sway bar first was spot on. Since this augments the existing sway bar and doesn't replace it, It really does makes a difference. I chose to have it installed by my local RV Shop, since they had all the equipment and tools to do it right. I paid them $225.00 for the install. The tech reviewed the installation video and was pleased I had all the torque data. I might tackle the front anti-sway bar and the Reflex Steering Stabilizer by myself, but this was more than I cared to tackle on my own. Those existing U-bolts are a beast to deal with for this do it yourselfer and I was glad to let him handle it. 669629

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


Installed this on my 2015 Ford F350 to help with truck camper sway. Super easy install for a Ford F350 if you already have the pencil thin stock sway bar. The Roadmaster model 1139-173 is the one you need since you can reuse your end links. The bar was packaged well. I was looking at the Hellwig Big wig first since it is cheaper and comes with new links. But it is extremely difficult to remove the existing link above the fuel tank. Also the Hellwig is a thinner bar. It came packaged very well and arrived only a few days after I purchased it on Etrailer. Overall very happy with the results. The truck corners well under load and sway is all but gone when fully loaded with the camper. 579086

The rear sway bars on my Tiffin motor home were so small that trucks almost knock us over. Has the new sway bars fixed the problem? No, but 80% of the sway we were getting is gone. Still needs track bar, and Sumo air bag helpers. Probably the best purchase so far for what we are trying to accomplish. Recommend them highly. 570979

    The only difference between Roadmaster front anti-sway bar # RM-1259-105 and # RM-1259-106 is that the latter, # RM-1259-106, also includes a Roadmaster TruTrac front axle track rod that keeps the front axle in line. It would be more stable than a new anti-sway bar alone. I have included a link to the instructions for both. As far as the front and rear anti-sway bars being different diameters, it will not be a factor since the front and rear axles are independent of each other. Also...

For the best of both worlds I recommend going with the front Anti-Sway Bar # RM-1259-105 and the Steering Stabilizer # RM-RBK13-RSSA. The trac bar is a piece of metal that adds stability while the stabilizer uses a spring to push you back to a neutral position.
