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 Rear Anti-Sway Bar Review

Speaker 1: Today we're gonna be taking a look at Roadmaster's Line of Rear Anti-Sway Bars for motorhomes. You want to refer to our fit guide to find the appropriate sway bar for your vehicle.The large size and heavy weight associated with motorhomes can cause drastic amounts of sway when driving down the road. To help create a safer ride, and reduce driver fatigue, we can minimize the sway by adding an additional rear sway bar. So when making basic maneuvers or sharp turns, you'll minimize the risk of a rollover.Also, when driving on windy days, on uneven pavement, you can get a sway affect going back and forth, and you'll have to compensate for that with the steering wheel to maintain and safe, straight path.This additional bar will help reduce that amount of sway, making it easier to maintain control of your vehicle and reduce vehicle fatigue, 'cause you're not having to compensate as much.The Polyurethane Bushings will help dampen road vibrations, and additionally stand up to corrosive road oils, salts, and UV rays. The bar is made up of 4140 chrome steel, where most factory bars are only made of a lower strength, 1020 steel.And to maximize your reduction of sway, Roadmaster recommends you also get a front anti-sway bar. Using our fit guide at etrailer.com you can pick out the appropriate rear and front end anti-sway bars for your motorhome.Now we'll take our anti-sway bars out on our test course.

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 then it was before, making it much easier to maintain control of the steering wheel.And then we'll head onto our straight bumps. When we hit those, there's a definite difference in how much forward and back movement than 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 onto our slalom where we can really test our the sway capabilities.

So if we have some evasive maneuvers, how our motorhome would react. And it's a massive difference. When turning, there's hardly any sway. I feel much more confidence taking sharp, evasive turns.Our customer David S purchased both front and rear Roadmaster anti-sway bars, and had this to say."I installed front and rear sway bars on my 2006 Itasca Suncruiser after making a winter trip to Florida from Ohio. We made a return trip this past winter, through the smoky mountains etcetera.

The improvement in handling was so noticeable, my wife noticed it from the passenger seat. I highly recommend both of these products. I have a workhorse w24 chassis. Crosswinds and semi-push was very minimal. One handed driving in most situations in the norm now, and driver fatigue was minimal.

Driving the coach is much more enjoyable."And that completes our look at Roadmaster's line of rear anti-sway bars for motorhomes.

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. 670674

2017 Winnebago Sunova Motorhome

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

I purchased this part because of the rocking on my 2011 Tiifen 34TGA built on the Ford F53 frame. After searching I found this on etrailer and I have to say the video and customer support from etrailer is outstanding. The part came quickly. The install is straight forward as the video shows but be prepared for some hard work. Getting the bolts off the frame after years on the road requires a lot of muscle, my 12 gal compressor and Harbor Freight air wrench was not upto the task. You will need a torque wrench that goes upto the 300 ft/lbs required for the plate install. We had to use our legs to get to 300. After installing I took a long test drive and the difference in handling is amazing. Much less rocking and more stable. I would recommend this anti-sway bar to anyone with this Ford frame. 509803


Comments

After a year of use the product is still rock solid and keeping my unit from rockin and rollin on the highway and local roads. I still recommend this for your MH on a the Ford F53 chassis.

Both sway bars made an incredible difference in the handling of my Winnebago Vista 27N. I also purchased a steering stabilizer and no longer have to fight my steering wheel to stay on the road. I am literally able to drive with just a couple fingers on the wheel. The rear stabilizer wasn’t the correct one for my Vista, cause I ordered one for 22,000 pounds, and it didn’t quite fit properly until I made a couple modifications. I did have to order the extended u bolts for the rear axel as well, and the hardest thing for me was removing and reinstalling the nuts on the u bolts. Overall I’m thrilled, makes driving much more pleasurable. 571969

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

Purchased Roadmaster front & rear anti-sway Bar and a Reflex steering stabilizer for a 2019 Winnebago Vista 27N. Heidi, etrailer.com customer representative, was extremely helpful assisting me with the order. Products were delivered in three days. The difference in which the RV rides with anti-sway bars and stabilizer installed is incredible. Much smoother ride with very little rocking. The RV is a lot easier to control when taking a turn. High winds and passing 18 wheelers are no longer an issue. The RV stays on course with very little effort on my part. Highly recommend these products for any RV no matter the size and a shot out to etrailer.com for their outstanding customer support attitude. 575252

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. 708174

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



- RM-1139-149
by:

Really improved handling in curves. No longer tips or leans over even if I drive in too hard. It's a challenge to do yourself due to the necessary torqueing but it can be done. I'm now wanting to get the front sway bar replacement. 666785

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

All I can say is these guys know their stuff and are more than happy to share their wealth of experience with you prior to purchase and after the purchase. They will not leave you hanging and wondering how, when, where-ing your purchase. They have how-to videos, knowledge base articles, and vehicle match algorithms that all help you pick and install the correct product for your vehicle. The shipping is surprisingly fast........fast fast. My confirmation email said it would be 7-8 days and the packages arrived in two days. When I complete the install I will update this review with fit and performance data. So buy with confidence! Paul 581052

I had my local Ford dealer install the Roadmaster Anti-Sway Bar along with Sumo Springs. They have really changed the handling characteristics of my gas powered Allegro 36LA. I now enjoy driving the RV along with the ride we get. The RV hardly moves when a semi passes and I can steer with one hand in light crosswinds. I would really recommend this set up for other gas drivers. 557424

The Road Master rear sway bar is Great but only because of etrailer with their installation video. The written instructions that come from Road Master are less than vague and incomplete.

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


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

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


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


Comments

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

  • Sway Bar and Steering Stabilizer Recommendation for 2016 Ford F-53 to Improve Ride Quality
  • The biggest ride improvement you'll make on the Ford F-53 is a rear sway bar. Next you'd want to do a front sway bar and then finally a steering stabilizer. Doing all three of those will make a night and day difference. For a rear sway bar you would want the part # RM-1139-149. For a front sway bar you then would want the part # RM-1139-140 and then steering stabilizer # RM-RBK4-RSSA. If you still want more at this point then Sumosprings would be the way to go.

  • Recommendations for 2017 Mirada Select Motorhome on Ford F53 Chassis with Sway Issues
  • The 2017 Coachman Mirada Select 37TB is built on the Ford F53 chassis. To reduce the sway, you are absolutely on the right track with the parts you are requesting. I recommend the following parts: Roadmaster Rear Anti-Sway Bar for Motor Homes # RM-1139-149 along with the Extended U-Bolt Kit # RM-590050-00 if the factory bolts are not long enough to accommodate the factory nut, washer, and a new 1/2 inch plate.

  • 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. This would make a massive improvement in the ride quality of your motorhome.

  • Suspension Enhancement That Fits the 2018 Thor ACE 27.2 GVWR 16000 on Ford F-53 Chassis
  • I think I can help make some confirmations for you and we'll go one-by-one on fits for your 2018 Thor ACE 27.2 with a 16,000 lb GVWR built on a Ford F-53 chassis. - Roadmaster Rear Anti-Sway Bar for Motorhomes # RM-1139-149 is NOT a fit as it is designed for vehicles with a chassis GVWR of 22,000, 24,000, or 26,000 lbs. Instead you would need the Roadmaster Rear Anti-Sway Bar # RM-1139-146 (assuming your Thor is less than 34 feet long). - Roadmaster Front Anti-Sway Bar for Motorhomes...

  • Rear Anti-Sway Bar for 2014 Fleetwood M-35K Class A Motorhome Built on Ford F-53 V10 Chassis
  • The 2014 Fleetwood Bounder M-35K Class A motorhome is built on a Ford F-53 V10 chassis and has a GVWR of 22,000-lbs. For this motorhome the correct rear anti-sway bar is Roadmaster part # RM-1139-149 which installs without drilling and that works along with the factory anti-sway bar which remains in place. Please refer to the two linked video for more on this product's features and installation. Part # RM-1139-145 is for RVs with a lower GVWR.

  • Recommended Sway Bar Upgrade for 2017 Jayco Precept on Ford F-53 Chassis
  • The Roadmaster Front Anti-Sway Bar # RM-1139-140, which is confirmed to fit the F-53 chassis that your Jayco Precept is built on, features the same 1-3/4 inch diameter as the existing Hellwig Sway Bar that you have installed. The Roadmaster model is a great sway bar, but it is unlikely to provide much improvement over the already upgraded Hellwig unit on your Jayco RV. For this reason, I do recommend looking at adding a rear anti-sway bar. A rear sway bar will actually make the most...

  • You are correct in that you will want to be looking at fits for the 2011 Ford F-53 chassis as opposed to the 2012 year. For your Class A motorhome with a V10 you will want to use the Roadmaster Front Anti-Sway Bar # RM-1139-140 which is 1-3/4" in diameter, and the Roadmaster Rear Anti-Sway Bar # RM-1139-149 which is 1-5/8" in diameter.

  • I reached out to my contact at Roadmaster and confirmed the parts that will fit your 2017 F53 26000lb chassis. My recommendation for a steering stabilizer is the Roadmaster Reflex Steering Stabilizer with Mounting Brackets for Class A Motor Homes, # RM-RBK22-RSSA.

  • Recommended Suspension Upgrade for 2018 Fleetwood Bounder 36D on Ford F-53 Chassis
  • I strongly recommend both front and rear anti-sway bars, and for your 2018 Fleetwood Bounder 36D on a Ford F-53 chassis with a GVWR of 22,000 lbs and a V10 engine the correct rear anti-sway bar is the Roadmaster Rear Anti-Sway Bar # RM-1139-149 while the front anti-sway bar is # RM-1139-140. For the rear bar you may need to use Extended U-Bolt Kit # RM-590050-00 if you find the square OEM U-bolts on your Bounder are too short. The Extended Kit gives you U-Botls which are 15-3/4".

  • Recommended Suspension Enhancement Kits for Winnebago Vista 35B Built on 2014 Ford F-53 Chassis
  • Aftermarket anti-sway and stabilizer products usually deliver substantial handling improvements over the OEM components on Class A motorhome like yours that is built on a Ford F-53 V10 chassis. Generally the priority is rear anti-sway first, then a front sway bar if still needed, then the steering stabilizer. There certainly could be cases where this priority may not apply but it is more often than not the best way to proceed. All such items for your 2014 F-53 are shown on the linked page. For...
