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 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.

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


The Roadmaster Anti-Sway Bar is of excellent quality. All of the parts are heavy duty and fit exactly the way they should. I have a 2003 Fleetwood on a Workhorse W22 chassis and considering the age all of the factory bolts and nuts came off without any issues. Installation was easy following the printed instructions and the online video. I really recommend this product.

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


I installed the front and rear Anti-sway bars with the steering shock.
I am 100% satisfied with the outcome and handling of my RV while driving down the road.
I would highly recommend the installation of these items on any RV


Comments
You just cant go wrong installing these kits to you RV. Next thing i looking to install is the air suspension kit and new shocks.

Was an fairly easy install with two people , has held up well so far . Helped stop sway with my top heavy truck camper load. At the time it was the only sway bar that fit the ram 3500 with 6.4 gas hemi due to exhaust system interference with other brands .

Sway bar has held up well since installation.

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


I recently purchased a 2011 Itasca Cambria 28 with only 10,500 miles. Our first trip made it clear that I needed to stiffen the chassis. Unfortunately Roadmaster Anti-sway bars are backordered, and though you should put those on first, I just installed the Steering Dampener. Easy installation though you need to be careful about seating the bushings. The videos are much better than the printed instructions. Already see a big difference in how much tighter the steering is. Can't wait for the bars to arrive. Disappointed to have to wait 4 weeks.


Comments
One year later, we have put over 22,000 miles on our rig, and added new tires. The ride is so amazingly better than without the steering stabilizer, and especially the anti sway bars. These additions are absolutely worth the time and money. I would strongly recommend them. You won’t regret it.

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


This is one of the best upgrades I have made to my 2016 F350 dually. The vehicle handles noticeable better while towing as well as without a load. I bought this stabilizer to help with body roll when cornering while towing my 19,000 lb 5th wheel. But I was surprised how well handling improved with an empty truck while driving down winding country roads. My truck now corners better than my wife’s Ford Escape (not exaggerating this). I state this a year after making this upgrade. If and when I buy a new truck, this will be one of the first upgrades I will make.


Comments
Still amazed at how well this anti sway bar improves the handling of my 2016 F350 DRW both while towing and unladen.

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


Easy installs on my 2004 E-450. The new Roadmaster 1139-115 front sway bar and the Roadmaster 1139-147 rear sway bar greatly improved the handling and cornering of the motorhome. I have aDraw-Tite 65001 front mount receiver mounted and there were no problems when installing the front sway bar.


Comments
It is actually a pleasure to drive! When cornering the motorhome would lean and things would slide around and i even had kitchen drawers open. The problems that i had no longer exist. The cost and the work i did to install were well worth it!

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


Relatively easy installation on my 2004 Ram 3500. It would have been easier if I had removed the spare tire. I only noted a few minor issues. The instructions say to mount the U brackets to the rear two holes in the shock mounts. However, on this truck the shocks mount one in front and one in rear. Therefore, the passenger side mounts in the rear two holes, but the driver side mounts in the front two holes. Otherwise all went well.

Great

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


Last year I installed the Sumo Springs (lighter load rated) front and rear and rear Koni FSD dampeners which helped noticeably on my 2017 Winnebago View 24J by stabilizing the ride.
I finally installed the Roadmaster rear anti sway bar RM 1209-120 immediately after receiving today. Absolutely worth the low cost for the major improvement in ride comfort and stability. These are direct bolt on replacements for the OEM Mercedes part and utilize the stock mounting bracket hardware.
For a total of less than $xxx I have completely transformed the ride of my Class C motorhome.

I’ve been procrastinating for years, I should have donne this modo à long long time ago. What a difference it made on my Kodiak based RV handling. Stop putting it off Do it now, you won’t regret it.


Comments
A year ago we installed a front Sway bar and Davis trueTrack. The combination of these component greatly improved the stability of our Super-C Motorhome. Strongly these components if you have stability issues with your RV.

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


Significant difference when making turns and going around curves. These twin I beam suspension have a tendency to follow uneven road surfaces, this pretty much eliminated a lot of that. Installed it myself with the Roadmaster end links and the only complaint I have is I had to enlarge bolt hole for the end link bolt, other than that, well satisfied. I also installed the rear sway bar at same time, highly recommend replacing the front and rear sway bars together.

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


11/2022 we were forced to leave Florida running from Hurricane Nicole. With 25mph cross winds and +15mph gusts our 2016 Vista LX, 31 footer, was a handful to say the least. Without eTrailers sway bars and bump stops we would have not been able to maintain our 50 to 55mph highway speed, better yet we probably would be in a ditch with other RV'S, 5th wheels and 18 wheelers. These items are amazing. I did have installed the Safe T Steer because eTrailer was way behind on their steering stabilizer. Thanks you eTrailer. BTW, if you are in the Indianapolis area I recommend Warner Springs on Bluff Rd. to do your install... Great people.

Definitely a big difference in the drive! I was expecting longer bolts that hold the sway bar.

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


The sway bar is high quality compared to the oem bar. I have a 2020 MBZ 2500 Sprinter 144. Basically, the roadmaster is three time the factory bar in terms of weight. And it shows. I took it on a ride down some winding roads and sharp turns and the back end feels much stiffer which equals control. I travel alot on Socal freeways to get to my destinations and it was very unnerving when driving next or passing freight trucks. I also pass through valleys and the winds can really making driving a bit uneasy. So, I anticipate this mod will add to my comfort level as well as my passengers. Time will tell. Now for some thing negative, well not quite but still some information buyers will need to know about installation. My van came with endlinks that were not compatible with the roadmaster. I knew this and order a set of end links for a 2019 model. Be aware that you will need new end links if you want to fit this bar to your 2020 model. At least that was the case for me. See pics. Overall, I'm satisfied and the cost is definitely worth the peace of mind.

just took a short trip with my motorhome about 300 miles with new anti-sway bars installed on front and rear axles, totally impressed with ride and handling remove sway from my motorhome about 75 to 80 percent.

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


--Etralier & Roadmaster Anti-Sway-Bar Review--

I
do not do product reviews--but am doing so here simply to express the AWESOME Customer Service, Articles, & Products at etrailer.com!

I have an old 1988 7.3 IDI (N/A Diesel) E350 transporter van (extended length with hightop) that I have spent a decade working on and just opted for front and rear Roadmaster anti-sway-bars.

I am so grateful I ordered them from etrailer! etrailer made the purchase process INCREDIBLE & the anti-sway-bars installed easily in an evening.

CUSTOMER SERVICE:

Via a private browser I inadvertently placed my order & received an error.

Hitting the "Live Chat" & within moments August from etrailer.com had answered saying my order was not in the system & it was safe to redo the order (which I did in a regular browser).

Just hours after placing the order (7 PM Pacific Time) I realized there was a third Roadmaster option (1 5/8" thick rear anti-sway-bar) I did not notice (see below for details of Roadmaster fit for the 1975-1991 Ford van, as I have worked out).

I again hit "Live Chat", at 7 PM!, & Matthew from etrailer within moments talked with a tech and confirmed I had (thankfully) ordered the correct part.

The next morning I awoke to an email from George at etrailer.com saying my order had been shipped and would arrive on Tuesday (~5 days across the U.S.).

The tracking link showed a map tracking the order as well who processed the order at etrailer.com (George), who gathered the order at etrailer.com (Cody), and who packaged (shipped) the order at etrailer.com (Michael)--with pics of the person.

The order arrived well packaged--from the factory I think--with only 2 cosmetic punctures (see pics if concerned--but for heavy (~36 lbs each) & awkward items across the U.S.--no complaints here).

Upon arrival, I received (what I assume is automated--but still) an email from Carol to follow up on the order.

Incredible!

ARTICLES:

Since then I have scanned some of etrailer.com's articles & they seem honest & insight-fully written (like the article discussing the cost/benefit, return on investment, of solar power*).

PRODUCTS:

There are also rather specialty products on etrailer I have wondered about but for lack of time have never researched (nor stumbled upon elsewhere). For example Kat's Heater Ether Start Fluid Injection System.**

Plus, from what I have gathered, they have product experts on-hand, with their names & pictures.

Do you know anywhere else with such customer service?!?!?

ROADMASTER ANTI-SWAY-BAR FIT
(for the 1975 - 1991 Ford Econoline van):

For fit, what I've worked out using the Roadmaster Fitmaster website*** is there are 5 variants for the 1975-1991 REAR anti-sway-bar & one item for the front (but do double check me!):

Part #1139-108 with a 1 3/8" anti-sway-bar: not for diesel
Part #1139-117 with a 1 1/2" anti-sway-bar: recommended for diesel E350 (what I contacted customer support over)
Part #1139-119 / RM83ZR with a 1 5/8" anti-sway-bar
Part #1139-108 with 1 3/8" anti-sway-bar: FOR auto-chain vehicles.
Part #1139-198 with a 1 1/2" anti-sway-bar: FOR auto-chain vehicle.

Part #1139-100 is 1 3/8" & is the only anti-sway-bar for the FRONT (I understand).

Unfortunately I have yet to test drive as I must tie several things down first & wanted to get this review out ASAP. But all reviews I have read say these anti-sway-bars are night and day difference.

SUMMARY:

In sum, there in no other company in the U.S, I have ordered from in over a decade that has done such a STELLAR job as etrader.com.

(And fixing/modernizing a 30 year old diesel van has required me ordering MASSIVE parts).

If etrailer is not one of the best companies in America, I do not know who is.

Order from etrailer with complete confidence.

THANK YOU so much etrailer!

Keep up the INCOMPREHENSIBLE job!

May you all be blessed,

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


The sway bar assemble was very easy to assemble. The directions were clear and all the parts were included. I would rate this as a critically needed addition if you plan to carry a camper in the bed of your pickup.

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


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.


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.

I purchased the Roadmaster rear anti-sway bar to help improve sway and cornering on my 2013 Fleetwood bounder 35K class A. Motor home. While towing my 26 ft enclosed trailer. It made a great improvement and would highly recommend it.

  • Rear Sway Bar Recommendation for 2000 Ford F-250
    The correct rear sway bar for your 2000 Ford F-250 is the Roadmaster sway bar part # RM-1139-153 which is a confirmed fit. This will help greatly with handling while towing. We aren't going to have a great suspension support system solution but we can offer you a setup that's actually better designed for towing. A weight distribution system helps with rear end sag by distributing some of the tongue weight up to the front axle. In doing so it reduces sag but also improves braking and handling. The...

  • Roadmaster Rear Anti-Sway Bar 1999 Ford Super Duty
    Yes, the Roadmaster Rear Anti-Sway Bar, # RM-1139-153 is designed to replace the existing part and designed to work with most aftermarket parts. This is a much stronger sway bar than factory, made with stronger steel than factory and increased to 1-1/4" diameter. Please see the attached videos for reviews and installation.

This is a thicker 1-1/4 inch bar that replaces the sway bar you currently have. No other parts needed to install it. Another option you might consider is the SuperSprings kit part # SSA22.

  • Are End Links Needed for Anti-Sway Bar on 1999 Ford F-350 With a 4-Inch Lift?
    Since your 1999 Ford F-350 has a 4" lift, the Roadmaster Rear Anti-Sway Bar for Pickup Trucks # RM-1139-153 is going to require you to use the End Link Kit for Roadmaster Rear Anti-Sway Bar # RM-590039-00. The spare tire will not need to be removed when using this Anti-Sway bar.

  • Do I Need End Links to Install a Roadmaster Rear Anti-Sway Bar on a 1999 Ford F350
    The easiest way to tell if you have a rear sway bar on your 1999 Ford F350 would be to just get underneath the rear of your vehicle and check. The sway bar will look like a thick metal bar that runs over the differential that will connect to the rear axle using u-bolts. If you do not have a sway bar you will need the end links like you mentioned, for that you will want part # RM-590230-00.

    While we have a good option for an anti-sway that will help with overall control of your 2000 Ford F-250 2WD, a steering stabilizer won't fit. The reason why isn't that they are too long or big, it's simply that the stabilizer won't physically fit because it installs in place of the steering damper which is there on 4WD options but not your 2WD. So the best option that will help keep your F-250 steady is a rear anti-sway bar, which does fit your 2WD 2000 Ford F-250: - Roadmaster Rear Anti-Sway...
