Features to know about

Better Control Through Turns: 3/4" Rear Anti-Sway Bar Reduces Body Roll

Sharp corners or quick lane changes can make a vehicle feel loose and unsettled. This solid 3/4" diameter chromoly bar ties the rear axle to the frame to balance weight transfer in every turn. The result is a flatter, more predictable ride that feels planted through corners and more stable during sudden maneuvers.

Steady Ride in Wind and Traffic: Keeps the Vehicle Level

Crosswinds and passing trucks don’t have to push you around. By minimizing side-to-side sway, this rear anti-sway bar helps the suspension hold a straighter line. That means fewer steering corrections, less wandering, and an easier time keeping things steady even when road and weather conditions change.

Less Fatigue on Long Drives: Smooth, Predictable Handling

Constant steering corrections can wear you out fast. With this bar controlling rear-end sway, the ride stays level and easier to manage mile after mile. It reduces the effort needed to stay in your lane, so you arrive more relaxed and confident no matter how long the drive.

Long-Term Strength: 4140 Chromoly Steel and Polyurethane Bushings

This setup isn’t built like a stock system. The sway bar is made from thick 4140 chromoly steel for superior strength and finished in a corrosion-resistant silver vein hammer-tone powder coat. The brackets wear a matching black powder coat, and the polyurethane bushings resist oil, gasoline, and ozone. That means less wear, more consistent support, and lasting stability over time.

Simple Installation: Mounting Hardware and Lube Included

No drilling required. The bar bolts directly to the rear axle and chassis using the included zinc-plated hardware. With clear instructions and bushing lubricant in the box, it’s a straightforward install that gets you back on the road quickly with a noticeable improvement in handling.

Video Transcript for Hellwig Big Wig Rear Anti-Sway Bar Manufacturer Discussion

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.

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!!

Glad to hear you are liking it, Mark! It's amazing how much stuff like this can help the overall experience! ^___^ What's the first trip you have planned now that you upgraded?

by:
2017 Ford Expedition
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.

Apologies for the inconvenience Jason, We definitely understand the frustration of having to unexpectedly run to the hardware store, especially when the instructions make it sound like you have everything needed to install. We appreciate the feedback and we hope the improved ride quality makes up for some of the inconvenience once you get everything dialed in. Don't hesitate to reach out if you have any questions and we appreciate you choosing etrailer!

by:
Fitment is a little tricky but with a little care not bad at all.

The additional effective spring rate when off camber is incredibly obvious and even with a loaded 250 lb RTT at roof height the truck feels very stable over uneven surfaces.

On normal bumps there is no additional harshness.

Highly recommended for 1st gen Tacomas with any amount of weight in the bed.

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

Can't wait to hear how your first trip goes, Deborah!

by:
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.

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.
by:
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.

Really improved the handling. Passing trucks on the interstate isn't as uncomfortable anymore. Generally I can now drive one handed. One person can change them but two would be easier.

The installation went well. Lots of rolling on the ground! Allowed two hours was closer to four hours when completed. Will need to get some mileage on the motor home to determine if it was worth it.

Glad this is making a difference Shawn and thanks for including the photo! What are you usually hauling with your RAM?

by:
sway bar adds strength to handle heavy tow and stability during normal driving. The big beast is actually much smoother with this and the Sumo spring helpers. It takes the annoying bounce out of the empty low weight drive also. Highly recommend!

Sumo and Hellwig working excellent together. Tow regularly near max weight and am very satisfied with the improvement in handling, leveling, and ride. I was afraid the unloaded ride would be stiff but it hasnt been affected. In fact, handling has improved over all.

Nearly 100% effective in preventing the dreaded semi-truck passing swing and sway on a 28’ Class C. Installation was easy even for a very amateur guy who hates working on machines. My compliments to e-trailer for the great videos.
First trip in this unit (IN to ND and back)was all white knuckles. The last trip (about 250 mi) was relaxing and I just grinned and waved as the trucks sped by. Well worth the $.
by:
2019 Ford F-350 Super Duty
Great delivery and super easy to install. Noticed a much bigger difference after replacing the rear sway bar with the hellwig bar than the front one. The factory front sway bar is already like 1 1/8 thick but the factory rear bar is only like 7/8 thick. I would start by replacing the rear first and then replace the front if you still want more. Overall very happy with the combination of the new front and back bars from hellwig.
by:
I'm using both front and rear swaybars by Hellwig, along with a Safe T Plus steering stabilizer, and it's been like night and day when compared to what was OEM in my '25 Ford E450. I no longer experience the super flighty feeling when driving in high winds, and, while I won't say it drives just like my car, it is a much more solid and stable, and relaxed, driving experience.

Sounds like you are getting things dialed in just right Scott! What has been your favorite trip of all time in your camper?

by:
Purchased this rear sway bar for a 2026 Ford Bronco. Greatly improved the on-road handling and stability.
by:
This with sumo front and rear and Bilstein shocks bought locally improved the stability of our sprinter class C by multiple factors.
The handling went from sucking to this is pretty good. Why did we wait 2 years?

That's awesome Jeff! Glad to hear your setup is working well for you!

by:
My rig was equipped with one inch sway bars, front and back. Today was my first trip since I installed the inch and a half bar on the rear. Wind gust were up to 25mph. It made a world of difference in the effort it took to maintain my lane. Still took a little effort. I may go with the one and three eights bar on the front, along with sumo assist springs. That should eliminate all sway.
by:

Very easy to install and the improvement with sway hauling a 4000 pound truck camper is amazing. I already installed the rear awhile back as well. I also installed new end links as well. 2000 Ford f350 4x4
by:
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.
by:
2023 Ford E-Series Cutaway
material quality appears to be excellent. My issue is with the fit. The clamps are significantly bigger than the original OEM clamps so the sway bar did not bolt right in to the original mounts. I had to modify the clamps to get the bolt holes to line up. Then when installing the end links, I found that the bolts were 2" short! I called the manufacturer and was very pleasently surprised when a human being answered the phone and directed my call to a specialist who promised to send the correct bolts and spacers for my rig. My RV is now stuck in my driveway, unable to move, until the parts get here.
by:
Our Jayco Ford E450 chassis is so much easier to drive down the highway now with the Hellwig anti-sway bar! Great price good videos and easy installation! Photo is old vs. new. What a difference.

Big and Beefy! For years, Hellwig has been my go to vendor when it comes to suspension augmentation for my towing needs. I am not surprised at the quality of this front sway bar. I am paired it with a new Hellwig rear sway at as well. It will make a huge difference when towing my heavy fifth wheel.

This is the second hellwig I have installed and still the same high quality I remember.
Unit was installed on a ram 2500 with a welding bed welder and all the tools
Definitely stabilized the truck and stopped the body roll
Install time approximately 1 hour kit had every thing I needed

Craig thanks for the kind words and we appreciate you choosing etrailer!

Hellwig makes a decent product and fills the gap of many aftermarket stuff. My order could have been packaged better and it was also missing the bolts for the control arm links. Other than that installation was straightforward and would consider purchasing from either company.
