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.

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

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

Fit and finish are excellent, good work. This should minimize sway far better than the factory bar. I am hoping that it will handle more like a sports car or the 3500 RAM LONG HORN that it is replacing. 398607

Winnebago vista 08. I believe this improvement was the least productive in improving my ford F53 chassis. My existing bar was already or close to the new bar diameter. The install was quick. Delivery was quick. Pricing was ok but they exceeded in having all three items for my rig. 406453

2015 Fleetwood Roadmaster

I purchased this kit and the Roadmaster rear anti-sway bar kit for installation on my 2015 Fleetwood Flair, 26-foot. Before purchasing, I called Roadmaster to make sure this kit could be installed on my small RV, as they make smaller kits for smaller RVs. They indicated it could be installed, and I'm glad I went with the heavier kit. The install took maybe an hour, with the only glitch being some difficulty getting the poly bushings and brackets over the new bar. I called Roadmaster, and the tech noted that the brackets DID look to small, but with some jiggling and finesse, the bolts should fit, and they did. My only irritation with this, and the rear anti-sway bar kit, is that the Roadmaster instructions do not provide ANY torque specifications for bolts to be replaced, either Ford F53, or kit specific, so be prepared to make some calls or go on an Internet search to find the right torque specs. 224319

I thank Cathy T great help she gave me. I installed the front and back anti sway bars on my 2016 George Town Motorhome. It has the ford f-53 chassis and a Dana 150 rear end. I use road master RM-1139-145 on the rear and RM-1139-140 on the front. Thanks to Cathy T she set me up with the right parts. I don't have any more body roll and the 18 wheelers bearly push me over now. If not at all. The front bar also cut down on wheel pounding. I have a much smother ride. I also have the road master reflex steering stabilizer Rm-BK9-RSSA. 293767

I received my front anti sway bar (RM-1139-140) around noon on the day it was promised. The package was undamaged and all parts were contained within. After lunch I installed the bar in less than 30 minutes, which included the removal of the factory bar. I installed it by myself from the ground. Simple install although I did deviate some from the instructions to make it easier for me as the bar is heavy. Instructions say to attach the bar to the axle with the bushings and saddle clamps first, then bolt the endlinks. Instead I bolted the endlinks first then simply swung/rotated the bar to the axle and attached with the saddle clamps. I did not have to lift the heavy bar to the axle as the weight was already supported by the endlinks. Easier if doing the install alone in my opinion. About a week prior I had installed a Roadmaster Reflex Steering Stabilizer ( RSSA-RBK9). These 2 items greatly improved the steering and sway problems which were extremely bad in my 2013 Winnebago Vista 26HE. So bad that I considered the drive extremely stressful and dangerous. With these 2 parts added the drive is now 80 to 90 per cent improved. Very happy. 263320

We almost didn't purchase our 2014 Allegro Open Road MH because during the test drive, I didn't like the significant sway as we made turns. I read online testimonies about sway bars and we we installed them. It has made a HUGE difference in the way our MH handles. So definitely recommend them to all MH owners! 893787

  • Sway Bars and SumoSprings for 2018 Winnebago 26 Intent Ford F-53 Chassis
    The general consensus with the Airtabs is that they are more of a gimmick than anything else. I would not recommend them for you. If you've already installed the Roadmaster sway bars part # RM-1139-146 and # RM-1139-140 as well as a steering stabilizer the next thing I'd recommend is SumoSprings # SSF-170-40-2 for the front and # SSR-184-40-1 for the rear and you'll have your motorhome handling very nicely.

For 15,700 lb, 18,000 GVWR models less than 34 feet long, use # RM-1139-146 which would install in conjunction with the existing sway bar. For 22,000, 24,000 or 26,000 lbs, use # RM-1139-149. The...

  • Sway Bar Recommendation for 2018 Winnebago 26 Intent to Improve Ride Quality
    Your 2018 Winnebago 26 Intent is built on a Ford F-53 chassis that is somewhat notorious for being hard to handle on the highway. The biggest improvement you'll make is with a new rear sway bar. Which for that you'd want the Roadmaster bar part # RM-1139-146 which is a confirmed fit. Next biggest improvement is with a front sway bar which the part # RM-1139-140 you referenced is the correct fit. With these two bars and your current stabilizer you'll have a much better ride quality.

  • Why Does Rear Sway Bar Replacement of Motorhome Help Ride More than Front Sway Bar
    The front of motorhomes are pretty standard for the chassis designers. Since most of the weight of the motorhome body will end up on the rear axle it's harder for chassis manufacturers to anticipate how to build the rear sway bars. We've found that by tightening up the rear of the vehicle with an aftermarket sway bar like the # RM-1139-149 the biggest improvement is made. Front bars like the part # RM-1139-140 do help but it's not as drastic of a difference.
