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.

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.

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

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

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

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

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.

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

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

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

I have completed the circuit of upgrading my F-53 RV chassis with Roadmaster anti-sway bars and steering stabilizer, and I am completely satisfied. I cannot the RV manufacturers put a RV on the market without these or competing product as standard or optional equipment. The front sway bar and steering stabilizer were self installed. Additional help was needed for the rear sway bar due to the 200+ pound torque and frame drilling requirements. ps> The instructions for the front sway bar indicated using the original hardware, but I used the new hardware provided. 230805


Comments

After a year, I am completely satisfied with anti-sway bar and steering stabilizer, without these additions, I would have traded the RV.

Wow!! Service was great , they helped me get the parts I needed for my 08 bounder with the f-53 frame. I told them the problems I was having and they told me that a front and rear sway bar also the steering stabilizer would do what I needed for now. I had also replaced shocks and at the same time I did rear sway bar. They a lone was a remarkable change. A few days later the steering stablizer and front sway bar came in, installed them in a few hours. I took what used to be a boat on ruff seas, and wow I mean WOW. I was able to take roads that would have me white knuckle and I was relaxed. I could drive one handed. Keep up with traffic even on a high arced road. It now drives closer to my one ton every day driver. I don’t fight the road. I now enjoy the drive!! Thank you Etrailer for your help!! 662866

2016 Jayco Alante Motorhome

I ordered the Front Sway bar replacement, the rear sway bar addition & the Steering stabilizer for my 32' 2017 class A Jayco motor home. I have not yet installed the Steering stabilizer yet as it was on back order. As for the ordering & shipping of all the products I give an A+. Everything went well, I received a follow up phone call from the company right after I placed the order. They informed me of the back order on the steering stabilizer & even asked me if I still wanted it. All was received as intended. Now for the good stuff.... I only write a review on something if it made a tremendous impact & these 2 sway bars did just that. I drove 10k miles on my motor home before I told my wife, either we upgrade the chassis or i'm getting rid of it. Upgrading meant buying a diesel in my opinion which basically means your doubling the cost of not just the unit but the maintenance of it as well. So I spent the $1,900 on the 3 products. Probably the best $$ I've ever spent. My last trip without the new sway bars was just terrible. I just completed my first long trip with the new sway bars, what a difference they made. In my opinion motor homes should not be allowed to be sold without these upgrades. I believe it to be a safety hazard without them. I'll let you know how much of an impact the steering stabilizer makes after I go on a long trip with that. I paid $450 to have the 2 sway bars installed. I'm a very happy customer. 662252

I was amazed at the difference the anti-sway bars made on my 2017 Winnebago Sightseer motorhome. Before, the motorhome would rock back and forth and lean when turning and would be blown over to the edge of the road in high wind. Now, it's like driving a car. Well worth it!! 643654

2011 Tiffin Allegro Motorhome

The anti sway bar came in very solid packaging. It's a heavy beast but it can be installed by one person, two would be easier but not necessary. I laid out the new bar next to the old one and you can really see the difference. Much more beefy. The new bar has less of a curve which I'm sure adds to its overall effectiveness in sway control. If you watch the videos on etrailer it goes in exactly as they show, no surprises here. After install I took it for a test drive on one of our many bad roads here in PA and the ride is greatly improved. My wife commented how much better the ride was on the passenger side as she doesn't feel a lean like there was before. I'm very pleased with the improved stability. I would recommend this to anyone with the Ford F53 frame. I added this to a Tiffin 34TGA, 24K frame. This is my 3rd upgrade on this coach. I added the rear anti sway bar and the front steering stabilizer, all purchased from etrailer. Their customer support and install videos are the two main reason I shop here and will get my sumo springs from them in the spring. Oh and their prices are very competitive. 583917

Quick delivery arrived on time, installed the road master sway bar along with the reflex steering stabilizer and sumo springs on 2011 Thor hurricane 31j. Install was not bad did all the installs in a day and a half and like others have noted would be nice to have torque values. Results after install was nothing but positive. Return to center with the steering stabilizer dramatically improved steering control. Sway bar improved the top heavy roll during turns along with the sumo springs really makes a great improvement on ride comfort. Sumo springs also in my mind helped with isolation of road noise and reduced the harshness of road bumps. 474644

This is the best possible upgrade to a Ford 53 chassis. It is like driving a different vehicle and virtually eliminated the side to side sway. The steering stabilizer eliminates fighting with the steering wheel and make it much easier to stay in the center of the lane. It I could do only one upgrade, these stabilizers would be it. Well worth the cost. 312471

I contacted etrailer and a delightful young lady had the missing parts shipped the next day. The install went well with everything fitting well. I test drove the 2014 Fleetwood Bounder today and there is a noticeable difference in how it rides especially cornering. Much more relaxing to drive. I also replaced the front sway bar with the 1-3/4" 1139-144. 163509

  • 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. For that you would want...

  • Recommended Components To Improve Handling of 2017 F53 Chassis Motorhome with GVWR of 18,000
  • The best way to adjust handling on your 2017 Ford F53 18K chassis is to start with anti-sway bars. I recommend starting in the back with the Roadmaster Rear Anti-Sway Bar for Motorhomes # RM-1139-146. Then I recommend the Roadmaster Front Anti-Sway Bar # RM-1139-140. These will help the handling by reducing body roll and diminishing the effects of crosswinds and shifting cargo by balancing the weight transfer. Then to assist with keeping your motorhome in line, I recommend the Roadmaster...

  • Comparing the Air Lift LoadLifter Air Bags and the SumoSprings for a 2015 A.C.E. With a Ford F-53
  • Adding the steering stabilizer and the front sway bar is definitely the first couple of steps that you want to take to help stabilize your motorhome. If you haven't already picked one out I recommend going with the Roadmaster # RM-1139-140 which is confirmed to fit a 2015 Ford F-53. Although air bags like the Air Lift LoadLifter 5000 Air Helper Springs # AL57240 would help to support the suspension and ultimately your ride, I recommend going with the SumoSprings as they require no maintenance....

  • SumoSprings for a 2018 Forest River FR3 29DS 18000 lb GVWR on a Ford F-53 Chassis
  • SumoSprings will definitely help to improve the ride of your 2018 Forest River FR3 29DS. For your Ford F-53 chassis with an 18,000 lb GVWR you want part # SSF-170-40-2 for the front axle and part # SSR-184-40-1 for the rear axle. The two greatest things about about the SumoSprings is that they do not require drilling for the installation and once the installation is complete there is no maintenance that needs to be done. You can also install Front # RM-1139-140 and Rear # RM-1139-146...

  • Best Suspension Enhancements for a 2018 Ford F-53 Chassis
  • For your 2018 Forest River FR3 32DS on a Ford F-53 chassis, I recommend first adding a rear sway bar like the Roadmaster Rear Anti-Sway Bar for Motorhomes part # RM-1139-145. I would then recommend adding a steering stabilizer like the Roadmaster Reflex Steering Stabilizer with Mounting Brackets part # RM-RBK22-RSSA followed by a front sway bar like the Roadmaster Front Anti-Sway Bar for Motorhomes part # RM-1139-140. A rear sway bar will almost always be the first upgrade you want to...

  • Recommended Front and Rear Anti-Sway Bar for 2018 Thor Hurricane 29M RV
  • Your 2018 Thor Hurricane 29M RV is built on the Ford F-53 Chassis. For the front of your motorhome, I recommend the Roadmaster Front Anti-Sway Bar # RM-1139-140 and for the rear you can use the Roadmaster Rear Anti-Sway Bar # RM-1139-146. When installed and used together, these will do a fantastic job of minimizing sway and driver fatigue by improving the stability and driveability of your RV. There is not a sway bar from Blue Ox currently available that will fit your RV chassis. I...

  • Torque Specs for Roadmaster Sway Bars # RM-1139-149 and # RM-1139-140
  • If you check out the install instructions for both the Roadmaster Sway Bars part # RM-1139-149 and # RM-1139-140 all of the torque specs are listed for each step of the install. There are enough of them at various steps of the install that it would be easiest if you just view the install links to see each figure.

  • Anti- Sway Bar Recommendations for 2017 Forest River FR3 30DS
  • I did some checking and it looks like your 2017 Forrest River FR3 30DS is built on an 18k Ford chassis so for sway bars you'd want the # RM-1139-145 for the rear and then for the front # RM-1139-140.

  • 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...

  • Recommended Anti-Sway Bars & Steering Stabilizer for 2016 Forest River FR3 28DS on Ford F53 Chassis
  • Your Forest River FR3 28DS has a V10 and has a GVWR of 18,000 lbs. Because of the weight being in-between our fit guide weights, I reached out to my tech contact at Roadmaster to confirm that the Rear Anti-Sway Bar you need is # RM-1139-146. For your Front Anti-Sway, you will want # RM-1139-140. These anti-sway bars will work well with your motorhome to balance the weight transfer and reduce body roll. It also diminishes the effects of crosswinds, shifting cargo, and passing vehicles. Finally,...

  • Best Suspension Enhancement for 2018 Forest River Georgetown 31R5
  • According to my research your 2018 Forest River Georgetown 31R5 is built on a Ford F-53 chassis, which is what the parts you listed will fit. The best way to enhance the ride of your motorhome is to add a rear anti-sway bar as it will most effectively limit the side-to-side movement and create a more balanced driving experience. The correct rear anti-sway bar for you is Roadmaster Rear Anti-Sway Bar # RM-1139-145 though this will only fit if you are certain that your 2018 Forest River's...

  • 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. The extended u-bolts may not be needed if you have enough room on your...

  • Recommended Handling Enhancement Kits for F-53 Based Four winds Hurricane 34B Class A Motorhome
  • In general it is best to start anti-sway efforts at the front of the motorhome, to prevent such handling issues from then rolling through the entire vehicle. For a front anti-sway bar I suggest Roadmaster's # RM-1139-140 which works on both V8 and V10 models. This no-drill install replaces the OEM sway bar with a beefy 1-3/4-inch-diameter 4140 chromoly steel bar that includes polyurethane bushings that last a long time. This will usefully stiffen the front end response. Next up in...

  • You are certainly not alone in looking for a way to reduce the amount of sway and body roll when driving a motor home but there are great solutions to remedy those white-knuckle moments when going side-by-side with a semi or meeting crosswinds. The best way to reduce the sway and enhance the ride of your 2019 Winnebago Intent 29L built on a Ford F-53 chassis is to add a rear anti-sway bar, followed by a front anti-sway bar, and after that a steering stabilizer.

  • 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...

  • How to Improve the Handling and Ride Quality of 2018 Forest River FR3 32DS Motorhome
  • I did some research and your 2018 Forest River FR3 32DS is built on a Ford F-53 chassis and has a 20,500 GVWR. The F-53 chassis is notorious for the ride quality you described. The biggest improvement you'll make is with a rear sway bar, which for that you'd want the # RM-1139-145. Next biggest improvement will be with a front sway bar # RM-1139-140. SumoSprings will help too and are a solid choice. For that you'd want the # SSF-170-40-2 for the front and part # SSR-187-54-1 for the...

I checked with Roadmaster and for your Thor ACE that features a GVWR of 16,000 pounds the correct sway bars are indeed the part # RM-1139-140 for the front axle and # RM-1139-146 for the rear axle. Both of these components will do an excellent job of keeping the RV in line during travel and just improving the overall driving experience on the road by adding stability and control.

  • 2018 Thor ACE 27.2 Sumo Spring and Front Sway Bar Recommendation
  • Yes, you can use Sumosprings on an RV that has Roadmaster sway bars and/or a steering stabilizer. The SumoSpring Rebel part # SSF-173-40-2 would fit and work well for you. A front sway bar would help quite a bit as well. For that you'd want the # RM-1139-140 which will help quite a bit.

  • 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...

For the front, I recommend using the Roadmaster Front Anti-Sway Bar for Motorhomes # RM-1139-140 if your chassis is up to 16,000 lbs, but if it is 18,000 then use the Roadmaster TruTrac Front-Axle Trac Rod # RM-TRAC-F550.

The Rear Anti-Sway is the first step I recommend to give you a better ride and reduce sway. The Roadmaster Front Anti-Sway Bar for Motorhomes # RM-1139-140 is the correct fit and will further assist with the effects of crosswinds, passing motorists and shifting cargo.

  • 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".

These springs are made for models ranging from 16,000 to 22,000 lbs. These springs will mount both on top and bottom but are not connected. They will absorb the road shock, but will also allow full axle movement so you will have the best steering ability and traction. For the rear, I recommend the SumoSprings Maxim Custom Helper Springs # SSR-187-40-1....

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.

  • 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.

  • Your 2018 Thor Hurricane 29M is built on a Ford F53 Chassis and has a GVWR of 18,000 lbs. For this motorhome I recommend starting with the Roadmaster Rear Anti-Sway Bar for Motorhomes # RM-1139-146 because the rear sway bar has the most impact on the overall driving of the vehicle. You do not need to use a hoist to install the bar, but you will be removing a shock, so it will be much easier if you have a free moving axle, but it is not an absolute requirement. It is not a difficult installation,...

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.
