Features to know about

More Control on the Road: 1-3/4" Rear Bar Reduces Body Roll

Nothing makes driving feel more stable than cutting out the side-to-side sway that knocks you around in turns or gusty wind. This 1-3/4" diameter Roadmaster rear anti-sway bar mounts to the rear axle and frame to balance weight transfer and reduce lean. Built from thick 4140 chromoly steel, it provides a stronger brace than standard 1020 steel, increasing roll stiffness and keeping your rig level through corners, lane changes, and uneven pavement.

Less Effort at the Wheel: Stable, Predictable Highway Handling

Crosswinds, passing traffic, and shifting loads can make long drives exhausting. By linking the chassis to the rear axle, this bar steadies the frame and minimizes the constant steering corrections that wear you out. The result is steadier tracking and a more relaxed drive, even on windy stretches or rough highways.

Durable Construction: 4140 Chromoly Steel with Polyurethane Bushings

Strength and longevity come from the details. The 4140 chromoly bar resists flex and twist far better than softer steels, keeping its shape and performance over time. Polyurethane bushings replace standard rubber, holding up against oil, gasoline, and ozone. They don’t squish out or deteriorate, so you get consistent support and a solid, responsive feel mile after mile.

Straightforward Installation: Mounting Hardware and Lube Included

With no drilling required, this anti-sway bar bolts directly to existing points on the rear axle and frame. Heavy-gauge mounting hardware, detailed instructions, and bushing lubricant are included for an easy bolt-on install. Once in place, it works seamlessly with most suspension upgrades and aftermarket accessories for a balanced, confident ride.

Video Transcript for Manufacturer Breakdown - Roadmaster Anti- Sway Options

Hello neighbors, it's Brad here from Etrailer and today, I'm with Jeff from Roadmaster. And today, we're taking a look at what you can do to your coach to enhance the suspension. So a lot of coaches out there, real top heavy feeling and people think, "Well, it is what it is. It's a big bus, you know, how do I improve this" But that's not necessarily the case. Roadmaster has a few different options to help make a better ride, overall. Definitely, it definitely does.

So typically, we educate our customer to let 'em know that yes, you can improve your ride or you can get that GT version suspension with your motor home. And how we do is we basically have to find out what's the root of the problem, okay. So typically, when a customer comes up to us, the very first thing they say is, "Hey, I'm constantly doing this when I'm going down the road." That that just means so many different things. So we actually ask a few more questions. "Hey, do you tow a vehicle behind your motor home Does it get worse when you put that motor home behind, or that vehicle behind the motor home And when it does, is this getting worse as well" And when the answer is yes, yes and yes, then we kind of know that the issue is tail wag at that point.

And that's usually fixed by a product called a track bar. And what it does, it just locks the rear axle in place. So it's not moving side-to-side. It's only moving straight up and down like it should, okay Or the next thing that I typically ask my customers is, is "Whenever you go in and out of turns, does it feel like the coach wants to roll over to its side" Most of the time, the answer is yes. And typically, the reason why is because when that coach or when the chassis was manufactured, they really had no Earthly idea what the final output was gonna be, how tall it was, how much weight was gonna be on it.

So you actually took center of gravity from probably a foot and a half, to a foot off the ground and all of a sudden, you're six feet off the ground or eight feet off the ground. We're putting air conditioners, solar panels, satellite dishes, everything else on top of these things. And we just need to drastically improve that. So how we do that in this case, is we upgrade the sway bars. In some cases, we're doing a remove and replace.

In other cases, we're actually piggybacking, adding a second sway bar to the rear or to the front of the coach. So sway bars are something predominantly, you see on passenger vehicles. And when I started working here, putting a sway bar on an RV, I go, "Well, I mean it's the same concept, why not" But seeing the difference, I've done sway bars on my own personal vehicle and the first turn you take, you go, "Oh, that's a lot better." Definitely. It's no different on an RV, in fact, it might even be. Jeff Much more noticeable. Yeah, absolutely, 'cause. Or before driving, it does feel like it's gonna topple over and you don't necessarily get sports car handling, but it's more response on the steering, it's more direct and you just feel a little bit more planted, more, honestly, confidence when driving. Yeah, and a lot of our customers are reporting back up, you know, they're saying up to a 60% increase in how they feel that their coaches is handling. And that's what we really like to hear and that's where we're trying to aim for. We wanna give that customer their vacation the minute they start out of the driveway and not once they get to their destination. Yeah, and so as far as sway bars, there's rear sway bars as well as front sway bars, correct Correct. So why would someone choose one or the other or should they go with both Typically, we suggest both. In some cases, yes, you can start off with the rear, but like I said, again, we like to suggest both because we're actually tuning the bars for the weight of that vehicle that it's gonna carry. So to have an upgraded bar in the rear and not one on the front, kind of does it a little bit of injustice. That's fair. Now something else too, as a long drive that's gonna wear you out is, is fighting the steering wheel back and forth and you guys have a way to fix that, correct Absolutely, we sure do. So once we turn and look at all the issues that the customer has, we determine what the issues are, we start talking to the customer and we resolve 'em by doing track bars, sway bars, the last and final thing that we usually recommend is a steering control. So basically, what the steering control does and essentially, is put center force pressure on a tie rod. So that way we're trying to hold that vehicle in a straight line. So if the customer has road ruts, if they turn around and hit potholes in the road, high winds, it's an assistance for that customer to keep in a straight line on their coach. Yeah, and that's, again, one of the installs, many of the installs that I've done is the steering stabilizer. And again, that's one of those, "Does it really make that big of a difference" Well, just going through our parking lot and cutting it, you let go of the steering wheel and it kind of still just tracks that way, whereas the steering stabilizer, you can see the steering wheel go back to center and then, when you're just going down a straight line, it just feels like it's in a nice natural groove. Jeff Yeah, sure does. So it's definitely a lot more comfortable, especially, you know, putting a lot of hours on the road or doing any twisty-turvy, you know, curvy roads out there, it's just gonna help balance it and kind of counter steer a little bit for you, bringing it back to center. That way, you're not having to fight that wheel back and forth. Now with both of, you know, our front sway bar, rear sway bar as well as the steering stabilizer, that's gonna get you a really good ride. And I think overall, better drivability, these also still work in conjunction with other suspension enhancements that you can add on as well, so you can really deck out the suspension of your RV. And I think it's. You'll be a believer once you start doing these, you're just gonna enjoy driving it more, I believe. Exactly, it brings the vacation back and the fun back into RV-ing. Yep, absolutely. Well, this was a look at some of the Roadmaster suspension components to just get your coach going down the road a little bit safer and a little bit more comfortable. Thank you Jeff from Roadmaster, for taking the time to break that down for us. All right, thank you.

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.

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

by:
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.

2022 Ford E-Series Cutaway
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.

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.
by:
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.

2022 Ford F-350 Super Duty
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.
by:
The products itself is good. Works well. But you would think when you spend $800 for something, the directions could be very detailed. There could be a complete video of it being installed. They don't give you specs for torquing any of the bolts and some very lousy pictures with a small amount of instruction. You can do better Roadmaster you want to charge me a lot of money for something then give me great detail on in installing it as well.
by:
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.

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

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.

I love this sway bar, and love the service and overall experience with etrailer. My F350 came with factory sway bars front and rear, and I'd replaced the rear bar several years ago, and was impressed with the difference it made. So, more recently I ordered the front bar to replace the smaller factory unit, and it again made a wonderful change for the better. Our Bigfoot truck camper is tall and heavy, but our rig handles wonderfully and has essentially no sway or rock in traffic or on bumpy roads. I highly recommend this sway bar.

The two Roadmastercsway bars weve been using continue to impress and perform like they did on day one. Driving back across the country with some days having stiff criswinds continually we rode comfortably and never had handling or steering issues. I remain adamant that these are undoubtedly the best products on the market for this application and welcome any questions. For reference my truck is a 2018 F350 crew cab DRW, 6.7 diesel 4x4 long bed with Bigfoot 3000 series truck camper. Get the Roadmasters!

I have a hard side slide in camper in the back of my pickup. This is the first time I installed an Anti-Sway Bar of any kind. It took me about 6 hours to install. But it works, and it works really well. I'm glad I took the time to install it.

Easy to install by myself in the driveway. I replaced both the front and rear anti-sway bars and the improved handling characteristics were noticeable immediately. Fantastic product!

2018 Ford F-53
Installation was 6/10 in difficulty only because of obstacles in the way of the top bolt on the passenger side end link. This was a step up to a 1 3/4" bar from the factory 1 1/2" bar. The end links were much beefier than the factory ones.
Initial test drive - I was impressed that the front roll on curvy roads was greatly decreased. This has been a significant improvement to driveability.

@BrookeM The air conditioner compressor, hoses, and hardlines were the obstacles. I may have saved some time and effort if if I had a right angle impact tool or maybe a wobble extension with a more compact impact gun, or even a fine tooth rachet. I was turning the upper endlink bolt one click at a time. My advice for any project, that I failed to follow this time... :(, is to dry run through the install to make sure you have what you need to do the job. You may have the right size sockets and wrenches but do they fit and effectively work in the space they need to? It's worth 10 or 15 minutes to do so and usually results in some new tools in your tool chest that you'll be thankful for on future projects.
