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.

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.



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:

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:

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:

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.

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:

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).



by:

Replaced the anti-sway bar on our 2019 F350. No special tools or jacks needed for the installation. Now our Lance 850 truck camper doesn’t sway nearly as much as before. Big improvement. Very pleased!



by:

The last thing to upgrade my front suspension on my 2018 Winnebago Aspect 27k. Money well spent! Easy installation, the ride greatly improved. Etrailer shipped this fast and I'm very pleased. Thanks.



by:

Major driving experience I upgrades my 2020 Thor Motor Coach KW-29 with front & rear sway bar, front steering stabilizer shock, All 4 front/rear Koni shocks, & Rear End stabilizer to chassis all together best investment on my RV improvement handling, body sway when 18 wheeler passing u up minimizing body sway from minor to none at all, reduce fatigue while driving course correcting steering reducing stress. Each component was felt the improvement but all together it’s been major improvement & experience



by:

Free from the roller-coaster ride my 2022 thor motorhome had with the factory bars.I have questions about why these companies don't install the suspension while building the rv.



by:

E trailer is.my go to place for anything towing trailering etc Absolutely the best products as well and the best service and the best people!!!!



by:

I installed both front and rear Road Master anti sway bars on our last RV and they made a tremendous improvement in handling. It was easy for me to install by myself in my driveway on out Coachman Leprechaun 319MB. I highly recommend this product.



by:

Item shipped quickly and the installation was fairly easy in my opinion. Have not been able to drive the RV yet but I'm sure this upgrade will improve the handling.



by:

After reading all the information regarding fitment for my 2001 Freightliner Chassis I purchased this rear anti sway bar kit which had a side note stating that if your chassis had different u bolts, which my chassis does I could contact Roadmaster engineering direct for the correct parts. I did contact them directly and they referred me to e trailer, who referred me to Roadmaster, pass the buck game. So after a year I have a half installed anti sway bar kit that is useless and unreturnable because it was half installed waiting for answers that never came. A waste of my time and hard-earned money NOT HAPPY.



by:

This is on a 2004 Dodge 2500 with a 2500 lbs truck camper, Dirt bike on a hitch rack, and 2 mountain bikes on a front rack. The sway bar definitely helps. This one fit well around my stupid 5" exhaust that was installed by the previous owner. The Hellwig would not clear it. I have the Timbren SES and wedges in my leaf springs as well. The sway bar is a nice addition to those items. What I really notice is that when making emergency maneuvers or going off road, the truck corrects quicker than before and feels safer and less likely to tip over. I would not say the bar by itself will solve all of your issues, but couples with other remedies, it will help make your top heavy overloaded ride feel safer. With all my additions, I can confidently go the speed limit and often times well above through the Colorado mountains with no issues.



by:

The antisway bar was a great investment. Between Etrailer'S videos and the packaged instructions, the installation was straight forward. Great product.



by:

On my 2021 Mercedes Benz class C Tiffin Wayfarer this rear anti-sway bar fit perfect. I didn’t have to make any modifications to the exhaust. With help I had it installed in 2 hours and 50 minutes. The pictures on the instructions could have been clearer to understand.



by:

I installed a front and rear sway bar and they solved the problem. Before that I had a serious problem with cross winds and semis passing. No more white knuckles!



by:

Front Sway bar by Roadmaster: Great. BUT the provided new bushing that fits in the factory bracket is too thick and needs to be trimmed to fit right. BOTH of these issues SHOULD NOT have to be tolerated by a buyer of what is supposed to be an expensive quality product!!! The staff is superb but they asked me for a PRODUCT review and both brands are not impressive on the hardware.

    For a 2024 Entegra Vision 27A with a V8 engine and F53 chassis you'll need the Roadmaster Exact Center Steering Stabilizer w/ Custom Brackets for Class A Motorhomes # RM63RR.

  • Recommended Suspension Enhancement For a 2023 Entegra Vision 29S On 2022 Ford F-53 V8 Chassis
    I have a better solution for you as the Timbren Front # TFFF53B and Rear # TFRF53A will create a very stiff ride for your 2023 Entragra Vision 29S. I feel their jounce springs are great for commercial applications and extreme weights but with the delicate trims and construction of your cabinetry the SumoSprings Front # SSF-170-40-2 and Rear # SSR-184-40-1 are going to be a much better option. These are constructed of a microcellular urethane which is much better at absorbing shock and will...

  • Which SumoSpring Helper Springs Fit a 2023 Coachmen Pursuit 31BH on Ford F-53 V8 18K Chassis?
    For your 2023 Coachmen Pursuit 31BH you will need the Front SumoSprings Rebel Custom Helper Springs # SSF-170-40-2 and Rear SumoSprings Maxim Custom Helper Springs # SSR-184-40-1. If you were to select only one to install first I recommend the rear springs since that is where the majority of your weight sits and they will help to reduce the amount of body roll you feel. If you are looking to get the best ride quality I have seen dramatic increases by adding both the SumoSprings above...

  • Steering Stabilizer, Sway Bars & SumoSprings For 2023 Entegra Coach Vision On Ford F-53 18K Chassis
    Yes, the Roadmaster Exact Center Steering Stabilizer # RM63RR is going to be superior to both the Bilstein and Safe-T-Plus steering stabilizers for your 2022 Ford F53 V8 18K Chassis under your 2023 Entegra Vision RV Motorhome. The Roadmaster has tandem gas struts that help to keep the steering centered rather than just dampening the travel like the shock type stabilizers you get from Bilstein and Safe-T-Plus. In my experience combining the steering stabilizer with the Front # RM72MR and...

  • Recommended Anti-Sway Bars for a 2022 Coachmen Pursuit 27XPS
    I checked with Coachmen and the 2022 Coachmen Pursuit 27XPS is actually built on a Class A V8 Ford F-53 Chassis which we do offer front and rear anti-sway bars for. For this, I recommend the Roadmaster Front Anti-Sway Bar part # RM72MR and Roadmaster Rear Anti-Sway Bar part # RM-1139-149. These will both do an excellent job of helping reduce body roll and the subsequent sway caused from this. I also recommend adding the Roadmaster Exact Center Steering Stabilizer part # RM63RR which will...

This adds a 2nd sway bar to the rear of your chassis. The Roadmaster Front Anti-Sway Bar # RM72MR will replace your front sway bar with a stronger unit.

  • Does The Roadmaster Front Anti-Sway Bar # RM72MR Come With All Necessary Hardware
    The Roadmaster Front Anti-Sway Bar # RM72MR is only going to come with two 5/8" shackle bolts for the end links and would require you to reuse the factory M14 bolts and clamps that should've been on your motorhome. If they truly are not there you would need to get in contact with REV Group, Inc. (the manufacturer) to determine what the length of the 5/8" bolts need to be or you could get some that are a few inches in length and cut them down as needed and get the some locking flange nuts...
