Nothing throws off your confidence behind the wheel like feeling the body lean or sway through turns. The 1-5/8" diameter Roadmaster front anti-sway bar ties the front axle to the chassis, balancing the weight transfer that happens when you corner or hit uneven pavement. The result is flatter handling, quicker response, and a steadier feel when maneuvering through curves or crosswinds.
This bar is built to take serious stress without bending or fading over time. It’s made from thick 4140 chromoly steel—tougher and harder than the standard 1020 steel used in most sway bar setups. That extra strength gives it about 30% better resistance to sway, keeping the vehicle planted and composed even when loaded or pushed through sharp turns.
Instead of soft rubber, the system uses polyurethane bushings and grommets at the attachment points. These resist oil, gasoline, and ozone, so they don’t squish or crack like rubber can. Less give means more consistent support and a tighter feel on the road. The bushings are lubricated to allow just enough movement for smooth rotation without sacrificing control.
There’s no drilling required to get this upgrade in place. The bar comes with heavy-gauge mounting hardware, clear instructions, and bushing lubricant for a straightforward install with basic tools. It’s designed to work with most aftermarket accessories, so you can add it to your setup without interference or extra modification.
Long stretches of highway or gusty conditions don’t have to mean fighting the wheel. By minimizing side-to-side sway, the Roadmaster front anti-sway bar keeps steering steady and predictable. You’ll notice less wandering in crosswinds, smoother tracking when passed by trucks, and an overall calmer feel behind the wheel.

Thanks Kim
The product was excellent, and the order process from E trailer was effortless.
If you are very handy with tools, you can do this yourself...but I wouldn't suggest it unless you are up for a challenge.
This is a great product, everything you need and vary simply to install took me around 4hr including a couple of trips to the store for tools. I also installed Sumosprings and what a huge difference.
The handling of my Class A was night and day difference with the bars on. Passing 18 wheelers were so much easier to handle as I felt very little push/pull.
Ordered during the pandemic, when everything was already backed up, but etrailer stayed on top of it and got my parts to me. Nothing but a positive experience with ordering and getting shipped.
Not to bad to install I did it at 73 year old. I first I did was lay out bolts nut were they go. Then I gather all the right at the tools to stop running back for tools. Everything went well. It took me about 4 hours to complete. Test ride went well I could see big difference. Next will be rear sway bar.
What I really like when order the part it was out of stock My salesperson call Roadmaster had drop ship. I had the part in 5 working day. There's no BETTER SERVICE then that.
I have a 2007 Winnebago Voyage 33V workhorse frame . I spent a lot of money trying to get this RV to handle correctly. I thought that the Workhorse frame had little sway to it and concentrated efforts to track bars front and rear and new steering box and a steering damper but had little improvement. My last effort was sway bars, front and rear and WOW what a difference!!! I ordered from E Trailer and to my surprise on day two it was sitting at my front door. Instructions were easy to understand and install wasnt difficult, took a couple of hours to put both on. I drove yesterday pulling a 27ft enclosed trailer in winds of 25 mph with gusts to 50 and was "Blown Away" by how stable the RV was after installing these sway bars. Easy one handed driving in the worst of conditions. I now am finally happy with my RV and look forward to next years cross country trip. Thanks E Trailer, I have bought several products and always appreciate the quick delivery and your follow up email to see if everything went well, its rare today to have your level of support.
Ordering was easy and my order arrived promptly and etrailer kept me up to date on the shipment!
No more boat on the water rocking. I installed front and rear sway bars, EXCELLENT Glad I did!
I cannot believe the improvement I got from this upgrade. 85% less roll and sway! MUST have. Very easy install in my driveway.
I have a 20210 30" forest river with the Workhorse W22 chassis
We purchased these a year and had them installed right after the lock downs started (of course), so have not down a lot of traveling. We did manage a couple of short trips though.
Before the Pandemic hit we would travel North during the Summer driving around 400 miles between stops. My wife would get up to fix our launch and I would have to tell her every time the road turned or there was a bump coming up, so she could hold to something to keep her from falling over. After we had the Front and Rear Anti-Sway Bars put in I have not had to tell her what is coming up. She say that she could hardly tell when I had to take a curve. I should tell you that we have a 2004 Class-A Gulfstream. We are so glad that we had these installed, wish we did it sooner.
Good product and well-made aftermarket equipment. Good improvement in overall roll and sway. Easy to follow instructions made installation much easier than expected.
Highly recommend
Usual excellent service— sway bar delivered on schedule. I’m in the process of installing the front swaybar for my Bounder and I will update once install.

The frint and rear stabilizer bars are great. Reduced sise to side sway abt 80. No longer cringe when passed bt 18 wheeler rigs. Needless to say increased drivability significantly. Not sure why not standard on larger rigs by Fleetwood.
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.
After a year of usage, I couldn't be happier with the Roadmaster front and rear anti-sway bar kits. The rear kit for my W22 chassy, the mounting hardward would not fit properly. I call Roadmaster directly and they custom built the mounts, painted, and shipped within days.

a quick fix it to install sway bars front and rear.
I did this and just came home from 2400 mile trip.
installed rear only before we left, then at our destination installed front.
the drive back it handles wayyy better and it sits level now.
""your results may very-use at your own risk. ""
from etrailer.com
rear = RoadMaster 1259-109.
front = RoadMaster RM-1259-105 with RM-590063-00 bracket kit.
i'm sure over time they will flex and stress and start to lien again.
But for now it looks much happier. ( and level )
and i'm very happier with performance and drivability
Seems the big bars help distribute the load to both sides,
you can drive it with one hand now.
and when a truck passes, it's very manageable.
( this could be part the tires on it )
these can be installed in about 6 hours pretty easy.
The hardest thing is drilling the 8 holes in frame. ( 4 front 4 rear. )
We had to shift 2 brake lines over via and small bracket and covers lines with old fuel like to act as wear buffer.
