Roadmaster Anti-Sway Bars - RM-1109-158
Highlights
- Custom Fit for Your Vehicle: Tuned to your suspension for better control and stability.
- Reduces Sway: 1-5/8" chromoly steel bar balances weight transfer to cut body roll and lean.
- Handles Crosswinds: Keeps the front end steady against gusts, passing traffic, and shifting cargo.
- Less Driver Fatigue: Steadier steering reduces correction effort for smoother, more relaxed travel.
- Improves Cornering: Maintains level control through turns and uneven pavement for predictable handling.
- Uses Existing Connections: Mounts to front axle and chassis with included heavy-gauge hardware.
Features to know about
Better Control on the Road: 1-5/8" Front Bar Reduces Body Roll
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.
Less Fatigue on Long Drives: Smoother, More Stable Handling
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.
Built for Strength: 4140 Chromoly Steel Construction
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.
Long-Lasting Components: Polyurethane Bushings that Resist Wear
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.
Straightforward Install: Heavy-Gauge Hardware and No Drilling Required
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.

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.

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.

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.

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.

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.

- Front and Rear Sway Bar and TruTrack for 2008 Jayco Seneca 36MS KodiakHey Phil, so your 2008 Jayco Seneca 36MS has a diesel engine so the correct TruTrac part is the # RM-TRAC45-5500 which is compatible with the front sway bar part # RM-1109-158 and rear bar # RM-1109-157. The front bar and the TruTrac do not attach to the same U-bolt so there wouldn't be any interference there either.
view full answer... - Recommended Suspension Enhancement for a 2008 GMC C5500 MotorhomeSteve, it sounds like you could benefit big time from a steering stabilizer # RM73RR if your GVWR is above 22,000, or # RM36RR if it's 22,000 or less. This is not going to work with your OEM suspension so you'd have to remove the factory one, but it is going to help keep your steering tight and prevent it from wandering all over the road. You're also going to need the mounting kit # RM-RBK5 to actually mount it to your vehicle. To further improve your suspension, you can also add a...

view full answer... - Recommendations to Prevent Sway on 2006 Jayco Seneca MotorhomeOne way to fix sway problems on a motor home is to brace the rear axle, to eliminate excessive axle side movement. The Roadmaster, # RM-1109-157, and similar products, mount between the rear axle and the chassis and hold the axle in place. This will greatly reduce rear end sway. Part # RM-1109-157is the correct part for the 2006 Chevrolet Kodiak. Adding a front sway bar is also an option. For a front bar, you can use # RM-1109-158. You could also install a steering stabilizer, # RM-RBK5-RSSA....
view full answer... - Front and Rear Anti-Sway Bars for 2009 Chevy Kodiak C4500From my research it looks like the Life Line is simply the box atop your 2009 Chevy Kodiak C4500, which would actually be the chassis. The anti-sway bars will not actually replace your Chevy's bars, they attach to the axle and chassis, which is why they do not look the same as yours. For an '09 Chevy Kodiak C4500, the correct Rear Anti-Sway Bar is # RM-1109-157 while the correct Front Anti-Sway Bar is # RM-1109-158.

For maximum stability you can also use the Rear Anti-Sway Bar, # RM-1109-157. These will fit the 4500 and 5500 models with or without the Granning Air Ride.

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.
