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.

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

Installed on MB Sprinter 3500 RV. Corrected sway and yaw when being passed by big rigs. Install directions were confusing. Called Roadmaster, they sent better instructions and talked with installer and solved the issue. 643712

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 received my order, but all the parts wasn't with it. All I got was the bar and the two bushing and brackets that mounts the bushing to the frame. All this came in one long box. According to the picture there are suppose to be more parts. I thought this is an expensive part for no more than I got with it. $ 600.00 for a bar really!! 211264

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

I have a class A motor home on an F53. They are scary to drive. Called Noah at etrailer.com. He knew just what I needed. Front sway bad, rear sway bar and steering stabilizer. Had them installed today and took about 100 mile drive. Wow, what a difference. Delivery was really fast and no one could beat them on price. I would use roadmaster products again.

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

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


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 product is great. The change in handling of my Ford F53 based motorhome is like day and night. The sway ( those of you who have an F 53 know what I’m talking about ) is so much more tolerable and no more white knuckles. The installation was straightforward but wasn’t as easy as it looked in the instructions. The torques were killer and took three of us to get done. The product does what Roadmaster clams it will do and I’m happy with the anti sway bar. 664236

  • Recommendation for Reducing Side to Side Body Roll on a 2003 Chevy Tahoe 4 Wheel Drive
    What I recommend to reduce roll is add some Timbren suspension enhancement. Part of what this system was designed for was the reduction of side to side roll. For a 4-wheel drive 2003 Chevy Tahoe, for the rear we have # TGMRG25C and for the front # TGMFK15A. What this system will do is reduce the space between the axles and the factory bump stops so it will not travel as far side to side. The spring will compress and the more tension put on it the more resistant it will be. I have included...

    An anti-sway bar is designed to help prevent body roll whether it be caused by turns or by cross winds, so it would certainly help in your situation. Taller vehicles like your Tahoe are more susceptible to cross winds due to the large surface area of the side of the vehicle.
