Minimize sway and driver fatigue by improving the stability and driveability of your vehicle. The bar on this sturdy, effective anti-sway system mounts to the front axle and to the frame to balance weight transfer and reduce body roll.

Specs:
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.
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.

Awesome service and delivery! Second time purchase at etrailer. Ships very fast to Canada ! Thanks again 870978
the roadmaster sway bars and the expert assistance from etrailer have transformed my motorhome which I was ready to sell to one that I can now enjoy driving. The swaying has stopped and it feels more secure on the road. Thanks again! 836890
Very happy with all the suspension parts I have received from them fast shipping . I will be ordering more from them in the future . 824908
I just received the sway-bar today. I haven't installed it yet so no review at this time. However, I would like to write a review on E-trailer. The first sway-bar got lost in transit by UPS. I informed E-trailer and they immediately sent another one. It was fast and no hassle. Thank you E-trailer. 784336
We love our Roadmaster suspension upgrades on our new 2019 Newmar Canyon Star 3722. 783184
etrailer was very helpful and professional to work with. I ordered the wrong parts and they assisted me on what parts I needed and made the return process for the wrong parts very easy. Keep of the great work! 766103
Helped my Thor Outlaw from side winds ...wish I could install the rear sway bar 746456
This has help reduce excessive sway of my motorhome and reduce driver fatigue. I have a 2017 Allegro. A local repair shop install it for me in about an hour. 732626
With the RM-1139-148 rear sway bar installed it definitely handles better than the stock chassis. However when you get up over 65 MPH it starts to give you the same characteristics of the stock chassis just not as bad. I'm glad I installed it because even over 65 It's still better than stock. 732171
handling is 100% better my F-53 chassis is actually drive able 731004
This Sway bar is a must add on if you own a motor home. I have a Tiffin 32sa and it handled better compared to most models that I have test driven but I wanted a better ride. I added this and a new rear sway bar system and the ride is like night and day. We also have the factory Sumo springs which is a plus as well. No more rolling into the turns. I also added a steering shock damper. No more drifting. All in all it was worth the money and saves on driving fatigue when on long trips. I highly recommend all items mentioned. 704948
bought the rear stablizer works great , hopeing the front one will to , have great confidence it will after the way the rear one did. 696070
Got delivery in a timely manner. All items were as advertised and installation hardware was complete. The Sumo Springs and heavy duty sway bars made a SIGNIFICANT difference in the ride and handling. Would have no problem ordering from this company again. They were also very helpful and patient on the phone. 669576
Sway bar arrived quickly. Instructions were not very detailed. For my Motorhome, Winnebago Adventurer (37F), I did not need the extra bolts, nuts and washers supplied and found no reference as to where they were needed. My original sway bar was attached with 6 bolts total. Have not test driven the Motorhome to verify for myself if sway has been reduced - hence the 4 stars vs 5. BUT, the bar is bigger and hopefully will help with that. Have not installed the rear bar yet. 640357
The sway bar was the right choice For the Ford Chassis RV. It really took the sway and darting out of the Coach. It was installed on a RB37 Thor Toy Hauler Coach. john 616347
I had these installed and they worked OK. Helped with the sway, but stiffened up the front so the ride was a little rougher. 572636
This was installed along with new rear sway bar. This required a little more effort as it was not exactly a mounting match, it was ordered and was supposed to be but wasn't. The bushing brackets didn't line up to the axle mounting holes, they were offset about 1& 5/8 inch on center and caused the bushing to sit right on the curve of the sway bar. I had to make 2 adapted brackets to allow it to fit the axle mounting holes properly. It wasn't a big deal as I have machine shop and engineering back ground. It along with the rear vastly improved the sway and handling of the RV. 502716
I ordered on Wednesday it arrived Friday morning . Installed in less then a hour. I also got the rear sway bar from in etrailer just as fast. Good customer service. 501850
I've purchased several items from etrailer, most recently the front and rear sway bar for a F53 chassis, and the products have arrived quickly and usually the shipping is included. Very happy with the site and service. 483222

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
Vince L - 08/30/2016Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars
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
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
