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 rear 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.


Roadmaster Anti-Sway Polyurethane Bushings

Superior Construction

The Roadmaster anti-sway bar is 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 anti-sway applications. In addition, the larger diameter of the 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 are durable yet flexible, ensuring that the system is neither so rigid nor so malleable that it becomes ineffective.

Hellwig doesn't list a heavy duty sway bar for my '09 Silverado 2500HD 4x4 so I went with this one. Helps tremendously with my heavy Arctic Fox truck camper.



by:

This sway bar has really helped when towing my 33' travel trailer!



by:

it helps with the sway when my truck camper is installed. Air bags also help with keeping the truck level when driving.

Received the Roadmaster Rear Anti-Sway Bar. Overall the product quality was very good and appears to be well constructed. Took about 2 1/2 hours to install. The only negative I have on the product was the instructions for installation was not very clear on what way the sway bar should have been installed - suggestion - turn the sticker around on the sway bar so you don't have to read it upside down for proper installation or put an arrow on the sticker pointing to the ground.



by:

The install was pretty straight forward and not very hard. I haven't been able to use it with my truck camper yet, but I that it will give me an excellent ride. Nice heavy duty item, I was/am impressed with it!



by:

This product is extremely stable with side winds. I’m not chasing my rv to stay in my lane.

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.



by:

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.

All the contents were delivered in the package. The kit fit perfectly as designed. Ordered for a Ford F-350 Super Duty. Truck handles great!



by:

Was told from etrailer that this was going to be a quick plug and play but no this was to be installed on a class c ( no drilling) but no , ustraps had to be adjusted did not fit and struts would not reach had to drill chasis



by:

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.



by:

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!!



by:

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.



by:

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.



by:

I am happy to finally have the rear anti-sway bar installed. Noticed the difference right away. I will order the front anti-sway bar soon. I have the skills to install the anti-sway bar, but did not have the heavy tools to do the job. Paided a local shop 2hrs labour, well worth it.



by:

I watched your video on the installation of the rear sway bar which I found to be helpful. I used an adjustable strap to level the sway bar before aligning and drilling for the links. Looking forward to a road test soon. Thank You



by:

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



by:

Your installation video was helpful. The front bolts on the the hangers required heating to break them loose. The factory was generous with blue lock tite. I might add the front bolts require a 18mm socket. Looking forward for a road test. Thank You always

  • How To Determine Correct Rear Anti-Sway Bar For 2008 Chevy Silverado 150
    Ok, so I checked with Roadmaster and both rear anti-sway bars are potential fits for your 2008 Chevy Silverado 1500, and the correct one to fit your truck will depend on the diameter of your current OEM sway bar. These trucks came with different size anti-sway bars so what you will need to do to ensure a fit is measure your current sway bar's diameter. If it is 1" diameter (which I think is the most likely option), you will need the Roadmaster Rear Anti-Sway Bar # RM-1109-176. If you...
