When a big gust of wind or a quick lane change throws your balance off, the 1-5/8" diameter Roadmaster front anti-sway bar keeps things level. It ties the front axle to the chassis so weight shifts are spread evenly through corners and sudden maneuvers. The result is a tighter, more predictable feel with far less body roll and less correction needed at the wheel.
Long stretches of highway or gusty conditions can make you fight to stay centered. This bar minimizes side-to-side motion and keeps the vehicle tracking straight, even when passing trucks or dealing with crosswinds. With the front end staying steady, steering feels lighter and you can relax instead of wrestling with constant sway.
Made from thick 4140 chromoly steel, this bar is considerably stronger than standard steel bars. The larger diameter adds torsional stiffness, which translates into up to 30% more resistance to sway compared to typical setups. That strength shows up in every turn—firm, controlled, and confident handling you can count on.
Instead of rubber, the system uses polyurethane bushings that hold their shape and resist damage from oil, gasoline, and ozone. They don’t squish out or soften over time, so you get consistent support and smooth pivoting where it counts. Less flex means more stability and fewer replacements down the road.
Everything you need comes in the box—heavy-gauge mounting hardware, bushing lubricant, and clear instructions. The design bolts directly to the axle and frame with no drilling needed. It’s a solid upgrade that works alongside other suspension components for balanced performance front to rear.
Ratings & Reviews
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.
Easy installation ,done by myself laying on my back in the driveway only took about 1 1/2 hours to do. I have a lift but didn't use it and I think it was easier on the ground for just one person. Sway bar made a big difference in the drivability of my 2003 E350 pleasure way class B
I'll upgrade the front factory bar to the HD Roadmaster bar soon
If you have issues with the handling of your Ford pleasure way start with this sway bar
Grate stuff. Easy to bolt up and figure out. Drive quality improved dramatically and less sway with trailers.
Just in the kit with the grease and red lock tight the hardware washers were one size to large so I got the right ones and installed all is well.
This is a must have for your Motorhome. What a difference in the ride of the coach through the highway washes, the side winds and the side drift of the big rigs. This bar reduces the coach movement by as much as 80% I would say. The installation is easy for someone who is mechanically inclined and still doable for DYIer as long as you have the tools ( standard 1/2” drive tool set, low speed high torque drill for the holes in the frame and a 250 plus ftlbs torque wrench). I would highly recommend this Anti-Sway Bar.
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.
After waiting 3 weeks the swaybar kit was drop-shipped from the factory. Received and discovered the bushing inserts were the wrong size (too small) for the bolts that were sent. Contacted Roadmaster support and provided them a photo and invoice as requested. The replacement inserts were approved and shipped out. I got metric bolts to go with the inserts I received. I will save the replacements for additional replacements.
The install was fairly straight forward.
Haven't had a chance to tow the 5th-wheel yet.
The anti sway bar is a big improvement when the truck bed camper is on. The installation took a bit longer than expected because the frame brackets don’t fit around an aftermarket B&W gooseneck hitch. I had to fabricate new top brackets and drill out the bottom brackets to widen the bolt pattern. Keep this in mind if you have a gooseneck hitch.
Received the product in a timely manner. The shipping company used I’d give a no star rating. I received the anti-sway bar bare out of a box or wrapper with the installation part box and a cut out piece of cardboard with the shipping label on it taped to the bare bar with about five yards of packing tape. The bar was scuffed, scratched and chipped with the RoadMaster label destroyed. I realize it’s going to be installed under the front of my motorhome but as much as it costed I would like to be the one to scratch and scuff it. If I was a company installing this on a customers vehicle I’d return it. I do not believe it was shipped from etrailer in this condition.
Great buying experience with ETrailer. Fast shipping and quality constructed part. Noticeable difference in controlling body sway. Very pleased with the bar and highly recommend Etrailer.
Excellent high quality product made a big difference in handling with heavy Artic Fox camper
Give poor rating regarding installation instructions
RM-1109-121 Rear Sway bar for 85 Chevyvan G30 RV. Install was pretty straightforward. I would mount the brackets to the frame first and then the sway bar to the axle. It’s easier to drill the holes without the sway bar getting in the way.
Before I replaced the shocks and upgraded the from sway bar and added the rear sway bar my G30 Chevyvan Winnebago was a wallow wagon. It took 110% focus to drive. Now it drives like a regular vehicle. Smooth. No leaning over when cornering. It’s night and day.
Britany is the BEST!!! Helpful and very professional. She kept me informed every step of the way.
No more getting pushed around by passing trucks! Easy to install as well.
Bar was out of stock when I ordered it. Took over a month before it got shipped. Not your fault. Got it and put it on. Easy job and it fits perfect. Took me about an hour fifteen. Motor home handles a lot better. That sway is gone.
Shipped same day ordered. Received several days later in great condition. Instructions from Roadmaster could have been better but got it installed myself.
The Roadmaster Sway Bar with Bushing Kit Anti-Sway was a great addition to my 2007 Chateau Chevy Diesel Duramax Motorhome. Stopped the sway. So glad someone told me about it.
I bought this product because my Super C was not confident and even felt unsafe. Spoke with Katy from etrailer, and they had the right knowledge to bring a viable solution. Now we ride with confidence and safety.
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.
Swaybar arrived 3 days sooner than expected! Super easy install.

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.
