Best 2021 Ford F-150 Anti-sway Bars

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.

So far so good; after installation of the stabilizer the rv steering straight as expected. I have not going the highway yet but... locally; the rig is doing well... and doing very well sitting at the drive way looking pretty!... i have to revisit this review for the final test of 1000 miles. etrailer's staff is very helpful in communication and responsive through email support. I rather pay little more for the product with the proper guidance and advice from etraile'r staff. I included a few pictures after i installed the stabilizer at night. On the installation; the instructions doesn’t instruct you to put red lock tight on the nuts; but i put the lock tight on there anyway to reinsure the nut doesn’t come off due to vibration since the bolt and nut holding the bracket barely shows any treads after torque.

I bought this stabilizer for a 99 class A Motorhome. The steering stabilizer kit came quickly and complete. Instructions are easy to follow. The whole install took about 40 mins. Just a couple adjustments to center the steering up. I initially bought the stabilizer because in strong crosswinds the motorhome was hard to maintain lane control. The stabilizer has improved handling. You must also insure that other steering components are not worn. I recommend the Roadmaster Steering Stabilizer for older Motorhomes.

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

First, I did have to grind off corner of the plate that mounts under leaf spring bolts. It would not lay flush so I tapered one of the edges where it met the axel a little bit till it laid flush. I did buy a 3/4 inch wrench set but with an rv, it's good to have and will possible allow me to get the 22.5 inch wheels off in an emergency. This with a good solid 3' pipe and I was able to fairly easily break the leaf spring bolts free. I used boards to ensure the fronts tires were fairly straight, laying them alongside the tires and eyeballing to see where they lined up with the back tires which are about 4 inches wider than the front outside width. I mounted the steering stabilizer and took it for a test drive and it was good the first time, no additional adjustments needed. Feels good on the road, good around turns, and even at low speeds around the driveway, I did not notice any extra effort to turn the wheel due to the heavy spring on the stabalizer. Put about 75 miles on it and it feels solid and stable though no high winds or passing semi trucks yet. But my 2007 ford f53 22000 lb chassis under a holiday rambler admiral body has always felt pretty good. Just trying to make better, next up is the new koni evo fsd heavy duty shocks coming today.

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

No issues. Significantly helps steering.

I received my front anti sway bar (RM-1139-140) around noon on the day it was promised. The package was undamaged and all parts were contained within. After lunch I installed the bar in less than 30 minutes, which included the removal of the factory bar. I installed it by myself from the ground. Simple install although I did deviate some from the instructions to make it easier for me as the bar is heavy. Instructions say to attach the bar to the axle with the bushings and saddle clamps first, then bolt the endlinks. Instead I bolted the endlinks first then simply swung/rotated the bar to the axle and attached with the saddle clamps. I did not have to lift the heavy bar to the axle as the weight was already supported by the endlinks. Easier if doing the install alone in my opinion. About a week prior I had installed a Roadmaster Reflex Steering Stabilizer ( RSSA-RBK9). These 2 items greatly improved the steering and sway problems which were extremely bad in my 2013 Winnebago Vista 26HE. So bad that I considered the drive extremely stressful and dangerous. With these 2 parts added the drive is now 80 to 90 per cent improved. Very happy.

I waited to write the review because on my initial test after install I could not tell the difference on the drive since there was virtually no wind. Today it was blowing hard with strong gusts. Drove about ten miles on the highway at 75 to 80 mph into strong cross winds and some areas with road construction in progress. It really works. Completely improved the drive. I still feel the wind bursts, but no longer have to fight for control. Highly recommend. Word of caution: the instructions provided by Roadmaster are inaccurate for my Ford E350 Class B+ RV. I will try to attach pictures.

WOW ! What a difference this makes. I was constantly correcting the steering while going down the road on my 2019 Chevy 4500 chassis class C even with no crosswind or trucks passing. Took it out after installation and immediately noticed a big difference. Took it up to 65 and it was great. Can't wait to see how it is on my next trip. Should reduce the white nuckle experience and reduce fatigue. Not hard to install in the driveway. Didn't even jack it up. I didn't need to readjust it. I can't understand why a couple of reviews that said it did nothing.

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.

The Anti Sway Bar completely removed impact of Semi Trucks passing us on the highway. It also significantly reduces issues with wind. Even reduced sway related to rough roads.

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...

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.

Made a huge diffence on a 10k+ trip to Alaska. Installed both front and rear sway bars. Night and day difference. Lot safer and more comfortable driving experience!

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.

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 group at etrailer are absolutely great. UPS lost my order out of the box and delivered me an empty box. Called in to etrailer and they took care of the claim with UPS empty box was delivered on Wednesday I had a replacement on Saturday. Totally a five star service

Sway bar installed easily and at least helped my Tiffin Allegro drive predictably now. I cannot say exactly how much because at the same time I installed a rear track bar and replaced all four shocks with Koni golds. Together the package made the rv drive much better eliminating side to side sway and porpoising.

I bought this product because my Super C was not confident and even felt unsafe. Spoke with Katy from etrailer, and they had the right knowledge to bring a viable solution. Now we ride with confidence and safety.

I’ve been procrastinating for years, I should have donne this modo à long long time ago. What a difference it made on my Kodiak based RV handling. Stop putting it off Do it now, you won’t regret it.

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.
