Made in USA

Features to know about

Tighter Handling Through Turns: 1-3/8" Solid Chromoly Bar

Body roll makes any big rig feel unsettled in a curve. This 1-3/8" diameter solid 4140 chromoly steel bar ties the front axle to the frame to balance weight transfer and cut lean through corners. The result is tighter, more confident handling when you turn or make quick maneuvers, keeping the ride level and predictable.

Steadier on the Highway: Minimizes Sway and Crosswind Push

When crosswinds or passing trucks shove you around, it takes constant correction to stay straight. This front sway bar limits side-to-side movement so the vehicle tracks steady, even in gusty conditions or around heavy traffic. You’ll feel more in control and less worn out after a long haul.

Built to Last: Polyurethane Bushings and Powder-Coated Steel

The system uses polyurethane bushings that resist oil, gasoline, and ozone, so they don’t squish out or deteriorate like rubber. That means less give and more consistent support over time. The bar carries a silver vein hammer-tone powder coat and the brackets use a black powder coat, both corrosion-resistant finishes that hold up for years.

Straightforward Install: Mounting Hardware and Lube Included

No drilling or frame mods required. The bar reuses factory end links and comes with zinc-plated hardware, easy-to-follow instructions, and bushing lubricant. With basic tools, you can bolt it on and be ready to roll with a more stable, better-handling setup.

Video Transcript for A Closer Look at the Hellwig Front Anti-Sway Bar

Hi everybody, Andy here with etrailer.com. Let's take a brief look together at this Hellwig front anti-sway bar. Now this anti-sway bar is designed to fit your 2021 to 2023 Ford F-150, and on custom fit parts such as this sway bar, I do recommend taking advantage of our vehicle fit guide. Simply input the year, make, and model of your vehicle and our fit guide will confirm that this will work for you, or if we have something comparable that will work for you. Now, this bar is designed to replace your factory installed front sway bar and this is going to reuse your factory supplied end links. And when you have this installed, this is going to help minimize side-to-side movement, improving the overall stability of your F-150.

This system is going to let you execute turns and quick maneuvers with confidence. It's going to provide a level ride for you even on irregular surfaces. This is also going to help reduce driver fatigue by minimizing the effort required to keep your F-150 in line. And this is also going to help diminish the effects of shifting cargo, passing motorists and crosswinds. Now, this anti-sway bar does for side-to-side movement what a good pair of shocks does for up and down motion, giving you a marked improvement in the stability of your F-150.

Now, the bushings are made of a polyurethane instead of the standard rubber variety, giving you a longer lasting system. They're durable, they're resistant to damage caused by oil and gasoline. So as you know, less wear means less give in the system and better overall support. Now, the diameter of this bar is 1 and 3/8 inches. It is made here in the USA of a solid heat treated chromoly steel giving you that superior strength.

And I would like to zoom in close up just a little bit just to show you this finish. This bar features a silver vein hammer tone finish, which not only gives you protection from corrosion, but the finish actually has little divots in it. So when you grease your polyurethane bushings and slide them on the bar, this finish is gonna do a great job of holding the grease in the bushing to prevent them from squeaking. This does include a set of instructions to guide you through the installation process, along with some additional hardware and bushing lubricant. The brackets that hold your polyurethane bushings are coated in a black powder coat finish to resist rust and corrosion, and this does have a limited lifetime warranty from Hellwig.

Well, I think that's gonna wrap up our brief look today. I do hope that our time together was helpful for you. Again, my name is Andy, thank you for joining me.

2026 Ford F-150
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:
It's been a year but I remember the bolts on the end links were different. Other than that it works great. If you do the back one you should do the front one too.

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?

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!

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.
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.

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:
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.
by:
We added the rear anti sway bars and steering stabilizer a few months after the front anti bars. All three make a world of difference driving our Class C motorhome. Wind and large trucks passing can still be felt but there's more control and quicker recovery.
by:
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 the tall wasn't too bad, Terry! Even if it took a bit to get done. Definitely let us know how it handles going down the road as well. I think you will be happy with 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.

@James I am glad we had the right parts to make your towing a little more enjoyable James =)

This product is a very beefy anti-sway bar that significantly reduced wind induced sway and vehicle lean when turning compared to the stock anti-sway bar.

In spite of my five-star rating, Hellwig should properly size the clevis on each end link. The u-plate separation differed by at least a quarter inch between the two. Both required some widening to accommodate washers and sway bar (which seems to be a common complaint).

Swaybay arrived on time and well packed. Installation fairly straightforward, but the bolts on my factory bar were very tight to loosen. I watched some videos on installation the Hellwig. One suggestion i recommend is to the coat the new bushings with soapy water to help when preceding on the castings. I was able to do the swap by myself. The factory bar was 1 1/8” so the Hellwig is much beefier. I haven’t driven this much, but in a test drive the side to side sway in noticeably reduced.
by:
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.
