Nothing kills confidence in a corner like feeling your rig lean or sway through a turn. The solid 1-3/8" 4140 chromoly steel bar mounts to the rear axle and chassis, tightening up the connection between them to balance weight transfer. That means more control through turns, far less side-to-side motion, and a ride that feels planted and predictable.
Getting pushed around by wind or passing traffic can make long drives stressful. This bar minimizes body roll and side sway so the vehicle tracks straight, even when wind or uneven surfaces try to move it around. You stay in control with less steering correction and a smoother, more stable feel on the highway.
By keeping the ride level and reducing the effort needed to stay in your lane, this setup helps fight driver fatigue. The bar uses the weight of the axle to brace the frame as it shifts through turns, which results in steady steering and a more comfortable drive mile after mile.
Instead of rubber, this system uses polyurethane bushings that resist oil, gasoline, and ozone for longer life and consistent support. The heavy-duty bar is finished in a corrosion-resistant silver vein hammer tone powder coat, with black powder-coated mounting brackets for extra protection. It’s a rugged build that holds up to real-world use.
No drilling or modifications needed. The kit comes with zinc-plated mounting hardware, detailed instructions, and bushing lubricant so you can bolt it on with common tools. Straightforward, durable, and ready to go, this rear anti-sway bar delivers instant improvement in handling and confidence.

Hello, everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at the Hellwig Rear Anti-Sway Bar for the Chevrolet and GMC vans. Now, this is a custom fit part, it is designed to fit the 2023 and newer Chevrolet Express and the GMC Savana 4500 vans. And on a custom fit part like this, I do like to recommend for you to go to our website, use the fit guide, put in your year and model vehicle, and it'll show you if this will work for your application. Now, this rear anti-sway bar will minimize side to side movement, improves overall stability of your vehicle. It'll let you execute turns and quick maneuvers with confidence.
Allows for a nice level ride even on irregular surfaces, and it even reduces driver fatigue, 'cause it'll minimize the effort that's required to keep your vehicle in line. Now, this part will include everything shown here on the table. It includes the anti-sway bar, all the black powder coated mounting brackets, right here we have the zinc-plated mounting hardware, even gives you some bushing lubricant, and a nice set of easy to follow instructions. Now, this kit is made with polyurethane bushings. And the polyurethane bushings are used instead of standard rubber variety, it gives you a lot longer-lasting system.
Basically, the polyurethane is durable and resistant to damage that can be caused by oil, gas, and ozone. And of course, less wear will mean less give in the system and better support. Also, normally, when polyurethane bushings are used on sway bars, the grease that's used on the installation will dry out over time, and the bushings might start to squeak. But what Hellwig decided to do is they did a different finish on their sway bar. If I lift this up, you look closely, it has a silver vein hammer tone finish on the sway bar.
What that does is it has small divots in the finish, and that'll help keep the grease in the bushings and keep the polyurethane bushings' grease to eliminate any chance of noise. Now, this bar is constructed of a thick 4140 chromoly steel for superior strength. The diameter on the sway bar is 1 3/8 inches. Now, this is designed to fit your vehicle and work in conjunction with its suspension system. Basically, it attaches to your rear axle and to the chassis, and it uses the weight of that axle to brace your frame as it shifts and turns.
Also is designed to avoid interference with most of your popular aftermarket add-ons and accessories. And this kit is made in the USA. But that should do it for the review on this Hellwig Rear Anti-Sway Bar for the Chevrolet and GMC vans.
Ratings & Reviews
Made the truck drive like a sports car! I can’t wait to put my slide in camper back on my truck and try it out . It’s bound to be an improvement.
Sway bar works as intended. But its showimg major surface rust. The paint did not hold up well. Other than that its fine
Easy to assemble,easy to adjust, made a difference when towing our 5th wheel. Better overall ride,
Our Ford E350 got blown all over the Interstate on trips. It was so dangerous at times. At first I installed Bilstein shocks and though they helped a little, installing the front and rear anti-sway bars and the steering stabilizer made all the difference in the world. I changed them all at the same time so I don't know which one helped the most. These are certainly quality products and are pretty easy to install.
These were very easy to install and have made a huge difference in the handling of the Motorhome. I highly recommend these to anyone wanting to increase the stability of their RV both on the road and also while parked. Added these first then later added the Roadmaster steering stabilizer and the difference is night and day! No more white knuckle driving!! Well worth the money.
Installation went very smooth. No issues, everything fit perfectly. Significant difference in the RV handling , stiffer ride and seems to handle the wind and tractor and trailers passing . Very satisfied and highly recommended.
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.
The install video and product description shows you can use it in place of your existing swaybar. I watched all of the videos read the directions and the brackets did not lineup. Made sure it was for my make and model, had to make it work by bending a few brackets to fit. If I didn’t already have my RV disassembled in my driveway and was a pinch I would have returned it.
Had my doubts about anti-sway making much of difference, but after I installed it and took it for a test drive, it was like day and night, along with a steering damper it almost drove like my pickup. I just don't understand why these motorhome manufactures don't install these things at the factory. This greatly improves handling as well as safety. So if you do the white knuckle death grip driving I would highly recommend you have this installed along with a steering damper. No regrets.
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.
It wasn't too hard to install yourself and it does make a difference with the sway
Hellwig makes a great sway bar, and etrailer has great service ! What more can you ask ?
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.
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.
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?
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.
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.
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!
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.
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.
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!!
