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 cadmium-plated 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.

Video Transcript for Roadmaster Front Anti-Sway Bar Review

Speaker 1: Today we're going to be taking a look at Roadmaster's line of front anti-sway bars for motor homes. You want to refer to our fit guide to find the appropriate sway bar for your vehicle.And this is what a typical sway bar's going to look like when it's installed. Yours might be slightly different depending on your chassis, but this'll give you an overall idea of how it'll look.Your sway bar will attach to your front suspension and your frame to help reduce sway when going down the road. You may experience sway when going over uneven terrain, hitting potholes, on windy days, or when passing by large traffic.Sway causes driver fatigue, because you're constantly having to fight to maintain straight line on the vehicle when it's swaying back and forth. This'll help reduce that sway, allowing you to have more energy when you get to your destination so you can do the things you enjoy doing.The polyurethane bushings will help dampen against vibration, and they're also resistant against road grimes, oils, and UV rays. The bar itself has a black powder coat finish to help resist against corrosion.This sway bar's made of 4140 chrome alloy steel, which is going to be significantly stronger than the typical 1020 steel that's used on your factory sway bars.Compared to most factory sway bars, it's going to have a larger diameter bar.

It's going to help increase torsional roll stiffness. This means there will be less twisting in the bar, making for a more stable, smooth ride for you. This will also make for safer travel. In the event of an evasive maneuver or a quick turn, the reduction in body roll that you'll get with this bar installed will help you maintain control of the vehicle, and can help reduce rollover.And now we'll take our anti-sway bar out on our test course. And when we go into our alternating bumps, you can instantly feel a difference in the amount of sway.

It's a lot more stable side-to-side than what it was before, making it much easier to maintain control of the steering wheel.And then we'll head into our straight bumps. And when we hit those, there's a definite difference in how much forward and aft movement we had before. It's definitely a more comfortable ride than what we had, and again it's easier to maintain control of the steering wheel.And now we'll head into our slalom, where we can really test out the sway capabilities. So if we had some evasive maneuvers, how our motor home would react. And it's a massive difference.

When turning, there's hardly any sway. I feel much more confident taking nice sharp, evasive turns.After owning this product for a year, our customer Wayne J. checked in and had to say, "It's an excellent product. Well made, great instructions. Easy install with proper tools.

Made an incredible improvement in the handling of our 35-foot motor coach with an F-53 chassis. Would definitely recommend to anyone wanting to greatly decrease sway in a coach."And that completes our look at Roadmaster's line of front anti-sway bars for motor homes.

Roadmaster Front Anti-Sway Bar - RM-1139-148

Average Customer Rating:  4.8 out of 5 stars   (368 Customer Reviews)

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.

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

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

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

I just received the sway bar today and was delivered very expeditiously. I do want to thank the etrailer staff for providing great service. I want to especially thank Conner L for working with me patiently to expertly advise me what I need to correct a sway issue I'm have with my RV coach. Conner is very well versed in RV technical knowledge and was a great help in suggesting options. My entire experience was very fluid through out the whole process. The assembly arrived quicker than anticipated and the shipping web site kept me informed as to where the shipment was each day. I'm looking forward to the benefits of my sway bar assemble as soon as it is installed. I am also looking forward to my next etrailer purchase. Thank you again. 545192

I purchased a Roadmaster antisway bar to replace the stock bar on my 2012 Pleasureway Excel Motorhome which is on a Ford E350 chassis. I did the install myself and instructions were very clear and was not too difficult to do. Handling is much improved, I have noticed less body roll when turning or going over bumps. I have included photos to show the difference between the stock bar diameter and the beefier Roadmaster bar. etrailer shipped promptly and customer service was great. 543343

The roadmaster antisway bar is still working great! As a side note, I also had installed professionally the Roadmaster Active Suspension. Between these two products, my motorhome now drives like it’s on rails. Anyone with the same Pleasure Way model should seriously consider both of these products.

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


Because I have an older rig- (97 Fleetwood Jamboree, 31 ft, class C) I wasn't able to find many reviews of the Roadmaster's improvements of this particular generation coach. Install was fairly straightforward, and on my initial short test drive I was very impressed. The rear of the whole rig was tight with way less body rolling, and handling on the highway has improved as well. After my short test drive, it was apparent that I will need to install the front anti- sway bar at some point as well. The rear is tight now, but the front still floats. I considered some other spring upgrades, but I'm happy I choose to start with the Roadmaster anti-sway bar. If the cost was lower, I would order and install the front now. 677752

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


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

Drove it from Texas to California and back. It handled like a sports car compared to before. My Son and I did the work ourselves.

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


I ordered both the Front and Rear anti-sway bar upgrade kits. The install on my 2016 E450 was quite simple, and accomplished easily in my driveway. The kit for the front was a simple remove and replace the OEM bar. The rear kit required drilling two holes to accomodate new mounting points. Other than that, it was also simply a matter of removing a few bolts, and replacing the factory bar. Some minor nits associated with the kits. The washers included in the kit for the rear didn't fit the bolts, also included in the kit. And, the instructions for the front kit didn't include torque specs for the bolts. A quick trip to the local hardware store, and a call to Roadmaster tech support solved the respective problems. Oddly, the Roadmaster tech guy read me THEIR instruction over the phone, and they DID include the necessary specs. I've intalled these kits on two different motor homes now. They work GREAT, and I highly recommend them if you're towing and it feels like the vehicle has a bit more roll than you like. HOWEVER, I would note that the difficulty of installation can vary widely. If you're planning to install yourself, I highly recommend downloading the instructions in advance, and crawling under your vehicle to check on accessibility. For the E450 kit, you'll have to be able to get under there with a drill, and not drill through any cables/lines that may run along the frame rails. You'll also have to be able to get a (typically somewhat large) torque wrench up in there. My experience suggests this can be nearly impossible on some vehicles without access to a grease pit or lift. Good luck! 302774

After installing this front and rear sway bar my RV, it handled much better when in windy conditions and being passed by large trucks. The front sway bar install was very easy. The rear sway bar was much tougher and ultimately I had to have Camping World install that one. It took them about an hour and half to install just the rear sway bar. This was installed on a 2014 Chevy express 4500 frame. 336983

After purchasing a 2017 Winnebago Sunova 36 Z, I realized there were several handling issues that needed to be dealt with to make the drive more comfortable. I researched and then asked the experts at etrailer to narrow down part numbers appropriate to my F53 chassis. With their guidance, I purchased "sumo- springs" front and rear, a "Roadmaster" steering stabilizer, and finally the "Roadmaster" rear sway bar. The addition of these parts has made the coach far more comfortable to drive. Not only does e trailer provide great assistance ordering coach-specific parts, but they provide awesome installation videos that are a great help. Thanks etrailer!! 522622

2017 E-450 Class C RV. I just received the road master front anti-sway bar: RM-1139-176, rear anti-sway bar:RM-1139-147and steering stabilizer: RM-RBK24-RSSC . I unboxed everything and Wow! what a difference compared to the other items. My son and I decided to go ahead and install the steering stabilizer- RM-RBK24-RSSC and it took us right at an hour. we would stop and watch the e-trailer video to make sure we were doing a proper assembly. It is a very helpful tutorial. The only concern I have is how close the tie-rod end of the steering stabilizer is to the radiator hose. It looks like it could come in contact. What we are going to try is to get a old radiator hose and cut a section out of it and wrap around the area where the contact could occur. I will post an update when we get the sway bars installed 350488

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

Product arrived quickly as usual with etrailer. The etrailer video was more handy than the accompanying instructions from Roadmaster. etrailer provided videos for both the early E450 and the later chassis installations. While essentially the same, there was a small difference of enlarging an existing hole on the early frame in my case a 2006 and having to measure to locate the hole on the later. It would be nice if Roadmaster included a parts diagram to help with assembly instead of small not clear pictures. I thought the parts package was short two half inch washers, I supplied them from my stock. The fittings on the Roadmaster bar are much heavier than the stock components. Installation is on a 2007 Coach House, motorhome. Took it for a test drive, big difference in handling. 460014

The sway bars really improved the handling characteristics on my RV (32 foot class A). The back and forth sway during and after cornering has been greatly reduced. 570016

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


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

Review from a similar Roadmaster 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.

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

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


I ordered both the Front and Rear anti-sway bar upgrade kits. The install on my 2016 E450 was quite simple, and accomplished easily in my driveway. The kit for the front was a simple remove and replace the OEM bar. The rear kit required drilling two holes to accomodate new mounting points. Other than that, it was also simply a matter of removing a few bolts, and replacing the factory bar. Some minor nits associated with the kits. The washers included in the kit for the rear didn't fit the bolts, also included in the kit. And, the instructions for the front kit didn't include torque specs for the bolts. A quick trip to the local hardware store, and a call to Roadmaster tech support solved the respective problems. Oddly, the Roadmaster tech guy read me THEIR instruction over the phone, and they DID include the necessary specs. I've intalled these kits on two different motor homes now. They work GREAT, and I highly recommend them if you're towing and it feels like the vehicle has a bit more roll than you like. HOWEVER, I would note that the difficulty of installation can vary widely. If you're planning to install yourself, I highly recommend downloading the instructions in advance, and crawling under your vehicle to check on accessibility. For the E450 kit, you'll have to be able to get under there with a drill, and not drill through any cables/lines that may run along the frame rails. You'll also have to be able to get a (typically somewhat large) torque wrench up in there. My experience suggests this can be nearly impossible on some vehicles without access to a grease pit or lift. Good luck! 302768

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

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


Two reviews - 1 for the product. 1 for etrailer. Product: Prior to purchasing this front sway bar, the corresponding rear sway bar, and the reflex steering stabilizer, driving our Thor FE30 was frequently a white knuckle experience. Our journey has frequently taken us on I-40 and I-10. Both roads are subject to high cross winds. Additionally, there is heavy semi-truck traffic on these Interstates. Our RV was difficult to control in both of these situations. Frequently we were pushed outside of our lane. The installation was super easy on all of the components thanks to the etrailer videos. I was concerned about my drill being able to fit into the tight space to drill the holes necessary for the rear sway bar. I bought stubby drill bits and that worked perfectly. I did not even need to lift the RV off the ground for any of the components. So far I have taken the RV on I35 twice. It was quite windy both times. It was like driving a completely different RV. No wandering out of the lane. The steering felt much more in control. etrailer: This is the second purchase that I have made from etrailer. Both experiences have been fantastic. Both times I contacted etrailer to make sure that I was getting the correct parts and all of the necessary components. Christina J helped me with the suspension and did a great job. The product reviews and installation videos are fantastic. I will continue to be an etrailer customer/fan. 475335

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


While not the transcendent experience some of the other users had, this did make a noticeable difference. My star rating represents a product doing exactly what it was supposed / advertised to do. I was told the rear anti sway-bar would eliminate 65% of the movement. And that is an accurate description of the improvement. It was most noticeable on uneven roads and highway ramps. When the coach would have rolled 3-4 times, it's now 1 time. And, on long sustained curves the degree of roll is less. I paid to have it installed. After looking at it installed, it would have been easy to do on my own. I recommend the anti sway-bar for anyone looking to reduce body roll. 443092

Installed easily in about 30 minutes. I took it for a test drive in a 35mph crosswind and it seemed to handle great but I am anxious to take it on the freeway. My only suggestion is that Etrailer list measurements with the product description because the front sway bar that my motorhome called for didn't fit and I had to return it and get a different one. 359473

Road master RM-1139-176 and road master RM-1139-147 front and rear sway bars for 2017 Ford econoline 450 - on 26xd Jayco Redhawk. Bought this Class C motorhome brand new. When I test drove it I knew I would have to replace the factory bars. They were way undersized. It was actually dangerous to drive and when we hooked up our flat tow it was really bad. When I installed the road master sway bars front and back it was really unbelievable at the difference it made. It actually made driving this class c enjoyable. Very stable. The bad sway is gone. Pulling my tow is now safe to do. These bars are expensive but I felt if it would help my swaying problem it would be worth it. My dealings with etrailer has been very positive and the videos they produce for installation is spot on. I highly recommend these sway bars. Also it took me working alone in my driveway about 3 hours to install the front and back bars. 464338

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.

  • Sway Bar and Steering Stabilizer Recommendations for 2019 Tiffin 34PA, 26K F-53 Frame
  • The 2019 Tiffin 34PA, 26K F53 chassis is built on a 2018 year Ford F-53 frame so the correct rear sway bar would be the part # RM-1139-149, the correct front bar would be the part # RM-1139-148, and then for a steering stabilizer you'd want part # RM-RBK25-RSSA and you'd be set.

The anti-sway bar will use the weight of the axle as a brace against the chassis so that pressure to one side of the motor home is countered by the sway bar. It minimizes the side-to-side movement that cargo shift, wind or passing trucks can cause. On some applications longer u-bolts are required to install this kit. For...
