Features to know about

Flatter Cornering: Rear Bar Reduces Body Roll

Few upgrades make as big a difference in control as a solid rear sway bar. The 1-1/2" diameter Roadmaster bar ties the rear axle to the chassis to balance weight transfer and cut down on lean in turns. Built from thick 4140 chromoly steel, it’s considerably harder and stronger than the 1020 steel that comes stock, so it resists flexing and keeps the rig level through curves, quick maneuvers, and uneven surfaces.

Steadier Highway Tracking: Cuts Sway from Crosswinds and Passing Traffic

That uneasy drift when a semi blows by or a crosswind hits is where this setup shines. By minimizing side-to-side movement, the bar keeps the vehicle planted and centered, reducing the effort it takes to hold your line on long stretches. Less correction at the wheel means less tension in the driver’s seat and a smoother, more predictable ride.

Durable Performance: 4140 Chromoly Steel and Polyurethane Bushings

This isn’t a part that gives up over time. The 4140 chromoly steel bar delivers superior torsional stiffness, and the polyurethane bushings outlast standard rubber by resisting wear from oil, gas, and ozone. Less give means more consistent support and better tracking, mile after mile.

Straightforward Installation: Heavy-Gauge Hardware, No Drilling Required

The kit includes the mounting hardware, lubricant, and instructions for a direct bolt-on fit. It attaches to the rear axle and chassis with no drilling, working cleanly alongside most popular suspension add-ons or accessories. Once it’s in place, you’ll feel the improvement right away.

Great instructions and nice, high quality fasteners.
Fitment was great and only minor adjustments to my Air lift air bags was needed.
I have a 2013 Ram 3500 Dually with:
-Torklift 30K hitch
-5” Exhaust
-Air lift 7500XL air bags.
The lower brackets for the air bags needed to be moved slightly and I had to cut the excess bolt off on the passenger side.

This is a complete game changer when using a truck camper Mine is an Arctic Fox 990. I would list this under a must have accessory when using a truck camper. Unloaded ride when you hit off camber bumps is slightly rougher, but hey its a Ram 3500 dually for hauling heavy stuff. Also the performance when carving twisty canyons with an empty truck is astonishing....Watch out Corvetts, here I come!

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.

I have taken a few trips with the Clatter Cabin now. It’s been enjoyable to drive. Since then I have replaced the exhaust from the engine back with 2 12 inch pipe. I was able to get the pre bent exhaust parts over the axle and clear your rear sway bar nicely. Now she purrrrs!

I have carried a truck camper for 7 years with just Timbrin blocks also from Etrailer and finally made the move to Roadmaster anti sway bars front and rear. Planning a trip to the west coast from Georgia next year and wanted all the help I can get for stability on the mountain roads. Have yet to test but Im sure it will be a noticeable improvement. When my wife takes the wheel so I can have a break she would see-saw the steering wheel to balance the load and it drove me insane. Hoping for relief for both of us.

Install looks great Steven! I can't wait for you to take it out for a spin so you can see the difference for yourself, it is amazing what a upgraded sway bar does to your ride, no more white knuckles for you, or your wife. What big stops do you have planned on your trip to the West Coast?

2025 Sprinter 2500 low roof WITH factory sway bar. Added this bar to control the terrible handling at the rear of these vans and it absolutely takes care of that. Be aware that you 100% need the retro-fit kit for this bar to be installed as the factory sway bar end links will NOT work. The retrofit kit that you need is the RM-590064-00.

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.

No complaints with the handling. This is a good sway bar!

After about a year with both the Roadmaster Rear Anti-Sway Bar and the TorkLift StableLoad Upper Overload Spring Upgrade on our truck camper setup, my experience has been mixed.

With the StableLoads, some of the mounting screws eventually fell out. I contacted etrailer expecting the issue to be handled under warranty, but instead of taking care of the replacement directly, I was referred to the manufacturer. Considering the age of the product and that it was purchased through etrailer, I was disappointed with how the warranty issue was handled.

As for the Roadmaster 1-1/2" rear anti-sway bar, it is a very solid and well-built product, but in our particular application I honestly haven't noticed a major difference in body roll while taking turns with the camper loaded. I have driven the truck both with and without it, and the improvement was much less noticeable than I expected.

Neither product is necessarily bad, but based on our experience, the improvement in handling hasn't been significant enough for me to strongly recommend them given the cost.

I prefer to purchase direct from most manufacturers due to tech support and service. However I find myself purchasing from etrailer.com more and more due to the positive experience, expert tech chat advice, fast shipping and great prices to name just a few. It makes all the difference knowing that you are communicating with a real person and not AI. The Roadmaster 1 3/8” rear sway bar has been my most effective purchase for my truck to date. The SuperSprings SuperSway Stops are right up there in effectiveness as with the rear sway bar. The rear sway bar and SuperSprings SuperSway Stops were very easy to install and I feel like I am driving a different truck. In combination, the two purchases have made the truck and camper feel like one vehicle; no longer does it feel like a truck with something in the bed. VERY stable on turns, twists, hills and angles. I cannot recommend these products enough.

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.

What I recommend is touching it up with a rust resistant paint like Rustoleum. We will be in contact with you about the damage. Please keep an eye on your email.

After a year and many miles I would give it a five star for sure. Made a great improvement over the stock anti-sway bar. With the rear and front RoadMaster anti-sway along with the RoadMaster steering stabilizer the E-450 33 foot class C motorhome drives like a dream. I highly recommend these three products. If not all at once then this order, 1st rear anti sway bar then 2nd front and then the steering stabilizer with the spring on it.

by:
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.

  • Anti-Sway Bar for 2023 Mercedes-Benz Sprinter 3500 Chassis
    Hey Brett! Yes, the Roadmaster Rear Anti-Sway Bar # RM-1209-131 is a confirmed fit for both your 2025 Winnebago View and, more specifically, the 2023 Mercedes-Benz Sprinter 3500 Chassis that the View is built on. This will be a great kit to eliminate the sway from semis and crosswinds, as well as body roll when turning corners or on on-ramps. The kit includes all of the hardware necessary for the install, but you will want to make sure you have a torque wrench (and other general shop tools)...

These will help improve ride quality by adding additional support to the factory suspension on your 2022 Mercedes-Benz Sprinter 3500 Chassis.

  • Recommended Anti-Sway Bar For A 2021 Mercedes-Benz Sprinter 3500
    If your 2021 Mercedes-Benz Sprinter 3500 is a van then yes, the Roadmaster Rear Anti-Sway Bar # RM43VR is the only compatible option. If your 2021 Mercedes-Benz Sprinter 3500 is a Class C motorhome then you also have the option of the Roadmaster Rear Anti-Sway Bar # RM-1209-131. The real difference between these anti-sway bars and the factory sway bar that came on your Sprinter is the thickness of the bars and the polyurethane bushings, which last longer than the factory rubber bushings....

  • Anti-Sway Bars For a 2023 Tiffin Wayfarer 25RW on 2022 Mercedes Sprinter 3500 Chassis
    Based on the information I could find on your 2022 Mercedes Sprinter 3500 cab and chassis it appears to come with a 1-1/2" rear sway bar. The Roadmaster Rear Anti-Sway Bar # RM43VR you found is designed to replace the factory bar but is a stronger steel than the factory unit so it will not flex as much. We do have the Auxiliary Sway Bar # RM-1209-131 which will mount in addition to the factory sway bar and can also be used with Bar # RM43VR above to give you the best reduction in sway.

  • Will Installing A Sway Bar On A 2020 Mercedes-Benz Sprinter 3500 Void The Warranty?
    Installing the Roadmaster Rear Anti-Sway Bar # RM-1209-131 will not void your warranty. Stuff like this is protected under the Magnuson-Moss warranty act. This states that unless the part added actually causes a problem, then installation and use of the part will not void the warranty. That said, the correct sway bar will depend on your vehicle. I see you entered a 2020 Mercedes-Benz Sprinter 3500 and there are two options available for this vehicle. I have both listed below. Cargo Van...

    I reached out to my contact at Roadmaster regarding your 2020 Sprinter 3500 and he said they only carry a replacement # RM43VR Rear Anti-Sway Bar. Since this is replacing the factory anti-sway bar with a thicker and more rigid bar, it is hard to imagine it causing a problem since it goes in the same location. They do not make anything for front anti-sway or a steering stabilizer. I hope this information is helpful.
