When your rig starts to rock through turns or while towing, this 1-5/16" diameter 4140 chromoly steel bar brings things back under control. It ties the rear axle to the frame to balance weight transfer and cut down on side-to-side sway. The result is flatter cornering and steadier handling when the load shifts or the road gets rough.
Long hauls or windy highways don’t have to mean constant steering corrections. By minimizing sway and keeping the vehicle level, this rear bar helps you stay relaxed and focused behind the wheel. Crosswinds, passing trucks, and uneven pavement stop tossing you around so the ride stays calm and predictable from start to finish.
This setup skips rubber for polyurethane bushings that hold up against oil, gasoline, and ozone. They don’t squish out or break down like softer materials, so you get consistent support mile after mile. The bar’s silver vein hammer-tone powder coat and the black-coated brackets fend off corrosion and keep the hardware looking sharp for years.
No drilling or fabrication needed. The bar bolts directly to the axle and frame using the included zinc-plated hardware. Everything you need — from detailed instructions to bushing lubricant — comes in the box, so you can get it mounted and enjoy the difference right away.

Hello neighbors, it's Brad here at etrailer, and today I'm with Vern from Hellwig, and we have some sway bars here and I've put sway bars on my own personal vehicles for kind of more of a motor sport feel. And so something like this makes a world of difference. First turn, just everyday driving. But I've also installed larger ones. This is for an F53 RV chassis and you wouldn't expect an RV to make a huge difference with sway bars or think about performance, but they're top heavy. And the first thing you notice as soon as you put one of these on, just stabilize it.
So what exactly does a sway bar do You know, a sway bar really works to keep a vehicle level at all time. And a level vehicle is a safe vehicle. So you have, when you go into a corner or hit a curb, going over a curb, your vehicle wants to go side to side. And that sway bar actively works to bring you back to level every time. So how does one take a sway bar and get it mounted up to their vehicle So typically, it's a pretty simple.
It mounts in four places. So you can see here, here is the sway bar, it mounts to the axle and then at the end it mounts with end lengths to the frame of the vehicle. So for instance, the end link would attach to the end of the sway bar and this would attach to the frame. So at that point it's mounted in four places, it's secure and it works, the sway bar moves with the frame rolling on the vehicle. So how does this have movement As the vehicle rolls, the sway bar is really a giant spring that wants to return to levels.
So as the vehicle rolls from side to side, it works to bring it, the spring action works to bring it right back to the level place. So is it squeaky at all or is there any road noise that comes from it You know, they come from the factory with rubber bushings. Every vehicle is a front sway bar. It comes with rubber bushings. Rubber bushings are great for when they're brand new, but rubber deteriorates.
Hellwig supplies in every kit. Urethane bushings with bushing grease. And when you mount it on there, the biggest problem with polyurethane bushings is when they dry out, they squeak. When have a hammer tone finish here and it really has little divots in it. And when you grease these up and put the polyurethane bushing on it, they really do a great job of holding that grease in there forever. You should never have to re-grease it there. So there's a rhyme and reason to our hammer tone finish. Brad So it creates little pockets, basically, to hold that lubricant in rather than pushing it out and drying out. Vern Correct, a smooth finish would, it just washes out of there pretty fast. So that's why we do the hammer tone finish. Now sway bars, I'm a big fan of them, but many people want to use jounce bumpers or airbags to kind of counteract that sway. What's your take on that We still helper springs and one thing that a jounce bumper or a helper spring can do is they can help limit sway. So what they do is they bring it to it and they come to a stop. So it does limit the sway, but only a sway bar actively works to bring it back to level. We wish we had a product that did both, but you really need a sway bar to bring it back to level. So a sway bar's actively always there fighting against it whereas your downs bumper you do have to close that gap before it engages. And really, I mean it does limit how far the vehicle will sway over. So they can still use jounce bumpers or airbags in conjunction with an aftermarket sway bar. Yeah, absolutely. And if somebody wanted to run SumoSprings or even our helper springs, they work well together. Now Hellwig also offers the Big Wig series. What is that The Big Wig series is a larger diameter sway bar really designed for the 3/4-ton and one ton truck crowd. The Big Wig really shines when you have a cab over camper or anything that creates a vehicle to be top heavy and sway more so it's really designed for a working truck. You can still use the Big Wig even if you don't tow or haul loads too. It's our adjustability. Let's use the Big Wig for that. In fact, anytime somebody has a one ton truck, I always recommend the Big Wig. So adding sway bars, just kind of to wrap everything up. I've seen the difference. I've seen the reviews I've gotten to install sway bars and see before and after. It makes a world of difference. Hard to quantify. It's something, a feel that only the driver feels and it really makes a world of difference. So if you have that top heavy feel, whether it be from a muscle car and you just want a little bit better turn in, a little bit more tight feeling and just kind of a nice planted car for more grip, or you wanna make your RV just a better driving experience and everything in between, Hellwig probably has a product for you. You know, the one thing we hear over and over is when somebody puts on a sway bar, the difference is night and day. It truly is. And once you get one installed, you'll see we're not just talking. This is truly an awesome product. And the great part about suspension additives like this is, once it's installed, there's really no real maintenance and you get the benefits of it every time you drive. So Verne, thank you so much for coming out here and representing Hellwig and giving us a little bit of a insight into sway bars. Well, we appreciate being here and look forward to taking care of your neighbors.

Thanks for the help on determining if my sway bar link is ok to use on my 2001 Ford E350 or if it's at too much of an angle. Attached are a couple of pictures I took of my install.
Please let me know if there is anything additional I can provide.
Installed on 2026 F150 Tremor 402B. As the stock sway bar is even softer than the standard F150 HD bar to allow for more independant movement when offroading, this leads to increased body roll while onroad. The Hellwig sway bar exceeded my expectations for stabilizing and flattening the truck in turns. To have the trucks full offroad capability I just need to disconect the endlinks.Truck now handles incredibly well onroad, which is where is will mostly be driven. Installation was easy.
Ordering was simple with the help of Andy. Item was delivered a day early.
We purchased the Hellwig front sway bar. Have only driven the unit back to storage (about 4 miles) so haven't been able to experience the end product. Can't wait to hit the road and not sway into another lane from an 18 wheeler going by us
The instructions say to use the original mounting nuts on the new bracket. However, the holes on the bracket are too large requiring the use of washers to avoid the nuts from being partially in the holes. For the amount paid, you would think it would come with all of the appropriate mounting hardware. Not happy being delayed until a run to the hardware store for install.
I hope the ride is at least improved.
Thank you Etrailer and especially Gabby for answering a few technical and part number questions.The Etrailer YouTube tutorials were very beneficial in helping complete this DIY project, no problem! The upgrades with the Hellwig front and rear sway bars improved the handling and reduced the rock-n-roll sway across rough roads and in the corners as well as large trucks and busses passing by. The upgrades also included a Safe-T-Plus steering stabilizer. This Thor Freedom Elite 25’ E350 chassis now drives more like a big pickup truck instead of a large RV. Thank you Etrailer, Hellwig and Safe-T-Plus. We’re ready to hit the road for long trips with confidence!!
Super happy with the product and perfor mance,
I had to deal with Hellwig for a couple parts that had poor welds. Also felt that the shipping box was inadequate as there was a hole in the box and it was all taped up.
Easy to install , we will see the handle while driving
And delivery was on time
I’m 80 and installed it myself! Very straight forward installation.
Installed on a 2024 Sprinter 2500 Cargo Van 144.
The directions provided do not go with the sway bar ordered.The directions provided did not give any direction in installing the the metal sleeves into the eyelets and there is no possible way to to fit four washers into the the channel at where the sway bar arms attach to the sway bar.
As described , process was vey good. Installed already.
My next birthday will be the big 80. I had no trouble with the install
once I got under my van to see how this sway bar would fit. It took me about
an hour to install. It could not have been designed any better. I took it for a test drive with a side wind which effects my high top van. A big difference and I am very pleased.
In stock and fast delivery. Kit came with thread locker, grease and printed instructions. Quick and easy installation.
Works great!!
Fast delivery and fit perfect for my Mercedes sprinter 1500 2022
The Hellwig Rear Anti-sway bar was a perfect fit and took about 1 hour to install. The delivery was right on time as well. I highly recommend etrailer.
Box arrived damaged and missing some bolts. Had to run to hardware store to replace. Other than that product looks well built
What a difference from the original sway bar which looked so any by comparison. I would feel sideways wind gusts every time beforehand, necessitating firm handling, but after installing it this was hardly noticeable. Best upgrade ever.
I recently installed the Hellwig rear anti-sway bar in my 2018 Winnebago Revel (2017 4wd Sprinter chassis). Huge difference in the way the van drives. The front feels much more stable on twisty roads. There were two minor issues with the install instructions. 1. The instructions describe multi-piece adjustable end links. The supplied end links were one-piece and not adjustable. Fine by me--simpler, lighter, right length for my van. 2. The instructions say to put washers either side of the bushing in the clevis of the end link. That was not possible with the supplied 1/8" thick washers. I bought some 1/16" thick stainless steel washers from my local hardware store. Works for me.
Overall, well worth the expense for me.
The sway bar works amazing and still have nice comfortable ride with stock suspension. No more sway from the winds or off camber turns. Noah, from e-trailer was very knowledgeable and helpful with the buying and installation process! I have already referred to friends for their vans and a third one is on the way.
Hellwig makes a great sway bar, and etrailer has great service ! What more can you ask ?

Craig thanks for the kind words and we appreciate you choosing etrailer!
The sway bar is definitely beefy and well made. Now that it’s installed I’m pleased with it and hope it helps with cross winds. Two small issues with the install. First we were missing the 2.75” bolts and Hellwig shipped them to me FedEx two day no questions asked but still a delay. Second, the U-Shape brackets are way too tight. Watched a video on YouTube and the guy warned us on this. There is no need for it to be this tight. Need to flex out the U brackets to squeeze in the washers. It’s almost impossible. Lastly the boxing of the bar is inadequate, it needs to be secured in better.

Sorry about that, Dean. We do have the instructions for this sway bar attached to this page, but you also should have had the correct ones included. I will have our stock checked to make sure they are all the right ones in there. The sleeves are mentioned in step 5, but I will admit to them being a bit vague. What did you install this on and how many washers did you get in there?
