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 rear axle and to the frame to balance weight transfer and reduce body roll.
Features:
Specs:
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.
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.

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 rear axle and to the frame to balance weight transfer and reduce body roll.Excellent customer service- something sorely missing in todays world! The quality and delivery of the product were top notch. I will definitely do business with etrailer in the future.
Went in place with some efforts,
Pictures could have been clearer
Weight was great
Dramatically improved the cross-wind stability when combined with front bar. Big investment in Material and Installation labor on both bars ~ $1800. Local shop charged $250 to install the front. A RV center installed the rear for $400.
Roadtrek Popular 210 on Michelin Tires handles stunningly well for a 9000 pound gross weight vehicle. Also mounted upgraded shocks all around and replaced deteriorated bump stops on front.
Replaced front sway bar attachment links with Chevrolet OEM for $85 for the set of two.
B-class Built on Chevrolet 3500 Express Cargo Long Chassis by RoadTrek Canada.
Amazing results. Now a little tricky to install for sure but for two men, about an hour or three. After a year, holding up perfectly!
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.
Helped the handeling of my motor home s ignificantly
Nice product. But Hardware was missing and I had to go buy parts. Is a bit more work to install than you would think. Also the directions are terrible, better hope you can visualize. I did by myself but sure would be easier with 2 people. Took me 3 1/2 hours
EXCELLENT PRODUCT, EXCELLENT SERVICE, AND QUICK DELIVERY!
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 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.

Very nice High Quality Anti-Sway Bar!
I picked up the end links and fabricated the frame mounts for the end links.
Turned out great and made a very significant improvement in the ride and stability.
Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars
Very straightforward installation and all the parts were of high quality. This is a substantial, solid sway bar. My RV feels a lot more solid on the road in curves etc. Very satisfied with the product.
Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars
I purchased the rear anti sway bar and end link kit because my 2017 Ford F350 single SRW did not come with a rear sway bar from the factory. The sway bar came with instructions and fits the truck well. The end link kit did not come with instructions, so I had to find an existing hole in each side of the frame to mount them to. Although there is a larger hole in the frame above the hole that I was mounting the end links through, there is not enough room to put a wrench on the nut inside the frame. So I welded the nut to a 1"x2"x3/16" steel plate. Then I was able to slip the nut/plate assembly into the frame and tighten the bolt. Additionally, there are no bolt torque specs, so I torqued the 1/2" bolts to 80 ft-lbs, and the 3/8" bolts to 60 ft-lbs. I have to hope that is sufficient. Of course, I shouldn't have to hope. That information should be included in instructions, and the nut/steel plate assemblies (or some other option) should be included in the end link kit. Although the finished product appears to be good quality, I gave it 3 stars due to the incomplete end link kit.

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
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
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 .
Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars
This sway bar is the real deal. Easy to follow instructions but I had it installed because I'm lazy. It took one hour labor

Once again e-Trailer exceeds our expectations! Their customer support is top notch! Kyle was very helpful with our order and followed up with an email to also advise us our delivery was made today along with helpful videos.
We can’t wait to get front & rear sway bars installed on our Class A Motorhome!
Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars
I have not been able to get it installed, it is too difficult for my me to do in drive way, the front was easier. I have however installed the front anti sway bar and Roadmaster stabilizer. very happy with handling improvement
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.
Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars
I added the Roadmaster Auxiliary Anti-Sway Bar to my 2022 Isata 3, built on the 2021 MB Sprinter chassis. Before it was added, there was significant sway on uneven roads, and major rolling in and out of driveways. My wife complained constantly about the sway, which is apparently much more prominent in the passenger seat. I am very pleased with the improvement in the ride and my wife says the passenger experience is significantly improved.
I was amazed that etrailer.com shipped my order within an hour of placing it and it arrived within 2 days! I took the (very heavy) box to a local hitch shop that is an authorized Roadmaster dealer. Even though they had never installed one before, they completed the job in the amount of time that etrailer.com estimated.
I just completed an 800 mile trip and I am very pleased with this addition to my RV!
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.
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.
