Most Popular Rear for 2021 Ford F-150

The guarantee to fit my 2016 F150 Ford was not correct. Mounting brackets to frame were too small. I had to contact Roadmaster and they expedited the correct brackets to me and everything bolted up properly. It does help with sway and especially with body roll on cornering.

Absolute love this sway bar. Truck feels very planted and stable. Purchased to improve towing stability consistently tow 20” cargo trailer at near gvwr. I can literally feel sway bar engaging as trailers sway or making corners.

The anti sway bar helped a lot, but my Fleetwood could use a little more help. Probably needs the front end too. I installed the model made for coaches a year or two newer and it went on much easier than the unit requiring frame drilling and coil spring recounting. I ordered both to cover myself, didn't open the kit for older chassis and sent it back - for full credit, except for shipping, which is fair. Trailer met each promise - product, dates, and return of the unused unit. 5 stars for service 3 stars for eliminating the sway. ETrailer provided EXCELLENT videos for installation, and did everything they said they would! My wife is happy and I'm her hero. That's always worth 5 stars!

I spoke with Jameson, he understood my issues and recommended 2 stabilizer bars. They were delived on a tight time-frame. These ba4s made all the difference in the handling of my Newmar Baystar Sport. THANK YOU FOR YOUR EXPERTISE!!

excellent service

Did not fit our 2014 Sunseeker with air bags. It contacts the rear differential. We contacted etrailer and right away they emailed us a label to return the item, and placed an order for a Hellwig anti sway bar which fit perfectly. They're customer support is top notch.

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.

Made a world of difference especially in wind and passing or being passed by large trucks. If you're a handy person you can install it yourself in a couple hours. I did, in the driveway.

I didn’t realize our motorhome had an OEM sway bar already installed which was left in place. Etrailer selected one for us that was heavier and more appropriate for our unit. Instructions were a bit to be desired but once installed made a world of difference. Their staff is very knowledgeable and didn’t try to sell me more than I needed. Thank you Etrailer.

The package arrived in a timely manner, just as promised. The installation went as described in the instructions and everything fit well. It improved the handling quite a bit. I already had installed “Sumo Springs” last year (worked great) and the sway bar controlles the sway even more. One thing I can add is, get a long 1/2” drill bit (8” long) to help with drilling the front bracket holes. The drill chuck on my drill, hit the link tabs, causing me to drill at a slight angle (horizontal holes). The biggest problem I encountered is that the bar contacts the exhaust pipe (1/4” gap) and makes noise when driving (see photos) . I have a diesel and the exhaust pipe is about 3” in diameter, which doesn’t help. I’m trying to figure out how to resolve this issue. I will update when I do.

This is the best upgrade we made on our 2017 mercedes Thor motor coach. Prior to installation it was a bear to drive in wind or even going around turns. This sway bar made 100 percent better drive. Well worth the money

Sway bar operates fine. However, the installation took over 10 hours due to rivets on the leaf springer hangers vs. bolts and with 80gallon fuel tank between the frame Camping World had real issues grinding the rivets and replacing them with bolts! In 2008 apparently GM used two methods to install leaf spring hangers. Even with advance research this was not well documented as a consideration and one roadmaster had limited knowledge of when I encountered the problem. etrailer did not stand behind this issue they left me to resolve and did not offer a return and credit. I have bought from etrailer prior with good results including best price match guarantee however have not purchased anything from them since this issue!

Can't recommend Enough...combined with front sway bar kit turned our Chevy Kodiak 5500 motorhome into a Corvette..night and day difference...can't believe I drove all those miles without one...

Originally, I was sent the wrong linkage for my 2022 Ford E-450. I found this out after installing the sway bar. The etrailer rep wouldn't just send me the correct linkage and I would send the ones sent by mistake back. The only way to get the correct linkage would be for me to uninstall the sway bar from the vehicle, package the complete assemblies and then return the large/heavy assembly back. At this point etrailer would then send me the correct linkage included in the correct kit. I didn't have the time to deal with all that so I resolved the incorrect linkage myself. Hope this helps, Don C.

About a year ago I upgraded the front and rear anti-sway bars on my 2017 26A class C Winnebago on a F450 cutaway chassis. This is the simply the best upgrade to date. It eliminated the body roll and awkward handling in a crosswind as well as the snake like movements experienced when passed by semi trucks. The addition of the Roadmaster anti-sway bars has allowed us to travel 70 to 75 mile per hour on the interstates with confidence and has reduced the fatigue of a long days drive.

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.

With about 600 miles pulling the RV, we are mildly impressed with how well our three-quarter ton tracks down the highway while pulling the RV. Well worth the upgrade. However, etrailer needs a video on adding the hangers. There are no instructions that come with the kit that cover the hangers. The hangers have different size bolts, the shorter ones fit inside the frame.

Have only taken a short test drive . But seems better not as much rocking side to side ! Would have been better as far as shipping goes , if the grease was in something else so it did not get broken open ? It gets on everything including the instructions !

Best thing I have done to improve the driving and handling of our RV. Thanks to ETRAILER for helping me get the right parts and their professional support helping me return the wrong part I ordered.

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.

The antisway bar I purchased was relatively easy to install, and the service department was quick to respond to inquiries. It made a dramatic improvement in driving the motorhome, handling in wind, curves and semi truck winds was quite improved.

Installed this on a 2021 Thor Magnitude rv and it made a good difference in the sway I get when towing a car. Great upgrade.

It's working fine. My only concern is that the original Ford parts that these heavy duty anti sway bars attach to the trucks suspension aren't strong enough to support them.

The product seems to be high quality but the instructions are not that great to mount the drivers side frame mount for the link . Not to easy to drill the holes to line up on the inside of the frame unless you drop the fuel tank to mark & drill them . I didn’t want to do that so my holes were a bit off & I ended hogging out the bracket some on one side to get the bolt to go through . Also didn’t know if the bar would clear my Banks rear diff cover & etrailer would have been willing for me to return it including shipping at no cost if there were clearance issues . Great customer service.

The sway bar makes a huge difference in the way the vehicle handles with a camper in the bed. Installation was a little bit tricky keeping the bolts straight through both sides of the frame. Under all I’m very happy.

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.

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

I have a class A motorhome, F53. I installed a Roadmaster rear anti-sway bar 1 3/4" diameter, a Roadmaster reflex steering stabilizer, 4 new koni shocks and 6 new tires. Now, it feels well planted on the road ! Its a combination. Very happy !

I have no more sway on our 2005 Fleetwood Southwind Class A after installing this sway bar. However, I must be honest, When I went to install this sway bar, I found that both of the bushings and one of the brackets that attached the factory sway bar to the chassis were completely missing. I replaced the bushings and bracket at the same time that I installed this Roadmaster HD sway bar. I can't honestly tell whish fix or the combination made the difference.

Finished installing somo springs and rear antiswaybar couple of days ago. Products seem to be of excellent quality and installation was relatively easy. Have not been able to get out on the road due to Covid-19 but hopefully will be able to travel in a couple of weeks.

Installed roadmaster anti sway bar on 2005 Fleetwood Southwind. Easy install works great, drives much better. Already have a track bar and a roadmaster front sway bar. Thanks for the quick shipping

The kit arrived in about 3 days and was complete. I installed this myself as I am pretty handy. Hardest part was getting to where the brackets attached to the frame for drilling. There was also a junction box of some sort that I had to loosen to access the holes to put in the bolts. Other than that, it was pretty straight forward as far as installation. If you're not mechanically inclined. I would suggest having it installed. It does make a huge improvement as far as tail wag and uneven pavement are concerned. I will be installing to front anti sway bars in the next month.

I submistted a review for both front and rear kits. Both etrailer and Roadmaster are great companies to purchase products. Roadmaster made custom parts and sent them within days.

This upgraded rear sway bar positively changed the drivability of my Class C RV to where I'm no longer fighting to keep it between the lines of the road - period!! I upgraded the front and the same time. The installation was a little harder than I thought it would be, however, in the end it was worth it! I took a lot of photos, so hopefully it will tell my story. I wasn't expecting to have to drill out existing threaded holes in the factory mounting location, as you'll see in the photos. However once completed, drilling through the rear frame section was a breeze. By the way, do yourself a favor and buy a new 1/2 drill bit before attempting this installation. I did need a second hand with installing the frame connector bolt, as it was difficult to hold the sway bar with one hand and install the bolt with the other. It's a tight fit where the stabilizer bar link fit between the frame and leaf spring. And by the way, watch yourself on any exhaust hanger bolt! I bumped into it more times than I want to remember, so just be careful. Bottom line: the manufacture of this 2013 Chevrolet 4500 series had no idea this was going to be turned into a 31' RV; therefore, it was necessary to upgrade the sway bars. As I previously stated, it makes it pleasure to drive, and when I arrive at my destination I'm a much happier camper! If you're thinking about upgrading this part of your suspension, don't just sit there, just do it! You'll thank yourself in the end!

Dramatically improved the cross-wind stability when combined with front bar. Big investment in Material and Installation labor on both bars ~ $1800. Local shop charged $250 to install the front. A RV center installed the rear for $400. Roadtrek Popular 210 on Michelin Tires handles stunningly well for a 9000 pound gross weight vehicle. Also mounted upgraded shocks all around and replaced deteriorated bump stops on front. Replaced front sway bar attachment links with Chevrolet OEM for $85 for the set of two. B-class Built on Chevrolet 3500 Express Cargo Long Chassis by RoadTrek Canada.

The sway bar is good quality and probably does help with the cornering and the wind buffing from the semi trucks on the freeway. The negative side is the bolts supplied adapter kit were under sized diameter to the point of ratting when you walked back and forth in the camper. To correct the problem I had to drill the poorly punched holes in the shackle to a true 1/2" then purchase new bolts and lock nuts that fit the bushings. After all the labor and expenses the sway bar has worked as intended with no noise. The other thing I had not considered was how much traction you loose on uneven ground but that is the trade off with better highway control.

Part fit perfectly, corrected excessive sway in my 2018 sprinter campervan, 144 inch wb, tall.
