Roadmaster Anti-Sway Bar Installed

Benefits of an Anti-Sway System

The Roadmaster anti-sway bar does for side-to-side movement what a good pair of shocks does for up-and-down motion. You will notice a marked improvement in your vehicle's stability as the bar works to balance weight transfer and reduce body roll. The anti-sway bar acts as a link between your vehicle's frame and its front axle, using the axle as a brace to more effectively balance the shifting weight of your vehicle as you maneuver it. Lubricated bushings allow just enough pivot and rotation to compensate for the pressure placed on one side of your vehicle when it goes into sudden maneuvers, hits crosswinds or encounters shifting weights.

The TruTrac System

Rut tracking occurs when your vehicle hits an uneven patch of pavement and is, consequently, pulled into that rut and off of the smooth pavement. With larger trucks and motor homes, this problem can be difficult to correct because you have to work even harder to steer back onto the road. With Roadmaster's TruTrac system, rut tracking is a thing of the past. The unique Trac rod attaches to the front axle of your vehicle, essentially holding it in place to prevent jarring and any unnecessary shifting. In addition to minimizing rut tracking, the TruTrac system helps to end driver fatigue by eliminating wander, which is the "loose steering" feeling that causes you to oversteer.

Roadmaster Anti-Sway Polyurethane Bushings

Superior Construction

The Roadmaster anti-sway bar and TruTrac rod are both made of 4140 chromoly, a chromium and molybdenum steel alloy. This type of steel is considerably harder and stronger than the standard 1020 steel that is typically used in suspension applications. In addition, the larger diameter of the anti-sway bar increases its torsional roll stiffness. The result is a bar that is not only stronger than the competition, but also nearly 30 percent better at resisting sway. The polyurethane bushings and grommets used at the attachment points in both the anti-sway and TruTrac systems are durable yet flexible, ensuring that the system is neither so rigid nor so malleable that it becomes ineffective.

2006 Workhorse W-Series

The good is that the parts are first class, and it works very well. Even being mechanically inclined, the directions could use an upgrade. Needs more help where the spaces go.

Donald J.


Excellent, only wishing Id had it before the first of 3 trips cross country trips. Made the RV much safer. Highly recommended on all RVs


I installed these anti-sway bars front and rear because I was fighting crosswinds and passing semi-trucks, very exhausting driving. Made a huge difference. Our old Newmar (Workhorse) had no sway bars at all.


The anti-sway bar and trutrac bar make a huge difference (with the rear anti-sway bar). Installation was straightforward, the parts all fit well.

2004 Workhorse W-Series

when I decided to upgrade my w22 workhorse suspension on my 36 ft Coachman Santara , the concern was sway and control on the interstate surrounded by the big rigs from 50 to 70 mph, My Coachman would get to be a hand full due to cross and push winds.
I installed the front and rear roadmaster sway bars, front and rear trac bars and a reflex steering stabilizer.
1) Roadmaster Rear Anti-Sway Bar - RM-1259-109
2),Blue Ox TigerTrak Rear-Axle Stabilizer TT2601
3), Roadmaster front Anti-Sway Bar - RM-1259-106 with trac bar
it now drives ai a far more relaxed condition , should have done it year ago


I installed this about a year ago, it helped the ride some, but the handing it really helped, You had to have hands on all the time, reminded me of a wreck looking for a place to happen, it is not for someone that can't do hands on installation, the instruction has a lot to be desired so if You can't use tools, hire someone to install, mine was missing a lot of bolts and nuts which was easier for me to run to Alabama Bolt and buy than it was to sit waiting on them to send re[placement, I would recommend this for anyone with a WorkHorse W22 or W24 undercarriage on your Motor Home......I also would recommend the kit for the rear, when installing this, like I said it helped, but nothing like what the rear did, read about it on that Kit


Amazing. Can't believe I've been literally rolling around the country without this. Can't wait to install the rear one now. Suspension is so tight. Awesome

2004 Workhorse W-Series

Instructions with pictures could be better.
The instructions are for the sway bar only then the trac stabilizer as another kit. Seemed like it was to generic of instructions.


It really added stability and made my motorhome more manageable to drive.


This has been one of the best improvements that I've made to my RV and I was able to install it in an afternoon. It helps with handling on bumpy roads and windy conditions. All RV's should have these.


Amazing performance upgrade


Great knight and day difference very happy with the purchase.


An outstanding product! Built to last. Great powder coat finish!



fast shipping. easy to install.




I have a 2017 Ford F350 Super Duty SRW, and we haul a heavy truck camper (Lance 1055.) I have Stable Load Uppers and HD airbags, but wanted to add a sway bar to add that extra layer of control, even though my truck has handled the camper well over the last 2 years and 10,000 miles. My truck did not come with an OEM sway bar installed, so I needed this kit that included the End Links too.

The Roadmaster Rear Sway Bar and End Links sold on etrailer are top quality products. They are robust and well made, with quality hardware to match. The product deserves a 5-star, and even unloaded, my truck handling improved right after installation, with improved cornering and no real impact on ride quality in my opinion. I have not yet loaded up our camper or towed our boat, but I have no doubt this sway bar will substantially reduce sway and will improve control and handling when the camper is loaded.

So why 4 stars and not 5?

1. I researched this product and the installation in detail. I planned on installing it myself and expected to find plenty of detail on etrailer's site, or Roadmaster's site, or the internet. My most pressing question was about where to mount the end links, and the orientation of the sway bar arms since I wouldn't be using the OEM end links. That information was no where to be found on the etrailer site, Roadmaster's site, or in any installation manuals. For a product and supplier that has likely sold lots of these to Ford Super Duty owners, I was surprised to find how little info was out there. The installation video on the etrailer site was helpful, but did not include any information for the end links, as they had a 2015 Super Duty and used the OEM end links already installed. I contacted etrailer and they told me to contact Roadmaster for more info on where to locate the end links with this kit.

2. I contacted Roadmaster. They told me they had no instructions and that despite my truck already having the cut-outs for the OEM bracket that attaches the OEM end links to the frame, that none of those holes may work for me. So they suggested I connect the sway bar brackets to the axle first and then see where the arms would line up with the end links. The tech also suggested that it wasn't critical that the end links were perpendicular
to the frame, but that I should try install the end links to allow the arm of the sway bar to hand as close to parallel as possible. No bueno. When I installed this the 14" end links (center hole to center hole) didn't allow for the arms to hang parallel to the frame. And I don't think it matters as the orientation of my sway bar and the arms looks about like every video or picture I could find on the internet of this year/model truck and this sway bar kit. It seems to function fine.

3. Installing it was a bear, especially the way they instructed me to. And I had to make some modifications to fit my truck, as the sway bar arms were rubbing up against my airbag mounting brackets. I got it installed, but the thin instructions turned what should have been a 60 minute job into 2 1/2 hours. A bit frustrating.

All in all, this will do the job intended and will provide me with peace of mind next time we load our camper. I am a bit frustrated that there were zero installation instructions specific to my year/make/model of truck given it did not have an OEM sway bar and the end links had to be installed with a bit of guesswork. You will also note in my pictures that I had to mount the end links to the sway bar arms differently on each side to make the bar fit around my air bag mounts.


Fairly easy install. Drilling the hole in the frame was decent started with a 17/64 pilot hole then the 17/32 final hole. Take your time and let the drill do the work.
Do be aware of the hole placement on the drivers side as there are brake lines and wiring there.


This product arrived on time, and is as described in company literature. I have installed the sway bars and the sumo springs on my 2019 Ford E3 26 foot Thor motorhome. Installation is fairly straightforward. Having said that, I am a retired farmer and I am quite familiar with this type of work. Having the proper tools makes the job go much quicker and easier. Installation of the front sway bar took a little under an hour. The rear sway bar is a bit more complicated to install, but he can be easily accomplished by someone of average mechanical skills, equipped with the proper tools. I strongly recommend removing the rear wheels to facilitate installation of the springs and the sway bar. I have not driven my motorhome yet, but will be taking an extended trip in March. I am looking forward to an improved ride.


Solid-built sway bar. Helps stabilize in wind while driving. Using on 2016 Thor Vegas 25.3 RV, notorious for suspension and driving issues. Using front anti-sway bar as well with Safe-T-Plus steering stabilizer.


Very heavy duty sway bar. Using it on a 2016 Thor Vegas 25.3 RV. Much thicker than original and still holding up fine. Helps to stabilize in high winds and passing trucks. Also added the Safe-T-Plus stabilizer to keep wheels from wandering.


This sway bar is the real deal. Easy to follow instructions but I had it installed because I'm lazy. It took one hour labor


OH My! If you are thinking about getting one for your P32 wide body. Please don’t hesitate. It REALLY Works. Take the white knuckle effect out of driving. EASY installation! Easy Ordering from etrailer. Roger helped me get through the buying process and shipped to my house in 2 days! Thank You!!


First, Eric was a great help throughout the purchasing and installation. I watched the tutorial numerous times and set up my tools. I bought a 3/4 inch torque wrench at Harbor Freight and a 4 ft galvanized pipe at Home Depot. I followed the instructions and the tutorial to the letter. The bar and mounting plates are heavy, so be very careful. This job isn't for a beginner, but if you are somewhat mechanically inclined, you can install it. The 300 Ft. Lbs torque of the 8 nuts took everything out of me. LOL...I adjusted the end links twice, and it leveled out great. Now, I will do a test run and see how it improves the handling of my motorhome. Its a 2022 Entegra Vision 29S.


This should have been original equipment.It ( 1995 Safari Trek) now drives like a completely different vehicle! I added Sumo Springs on the rear .These 2 items together are well the money. I installed both alone by myself (67 years young).

    The only difference between Roadmaster front anti-sway bar # RM-1259-105 and # RM-1259-106 is that the latter, # RM-1259-106, also includes a Roadmaster TruTrac front axle track rod that keeps the front axle in line. It would be more stable than a new anti-sway bar alone. I have included a link to the instructions for both.

    The front trac bar that comes in the Roadmaster Kit # RM-1259-106 that you referenced will do the same job as a steering stabilizer but won't be as effective. For the best of both worlds I recommend going with the front Anti-Sway Bar # RM-1259-105 and the Steering Stabilizer # RM-RBK13-RSSA.
