When you’re hauling weight or pulling a big trailer, handling can feel loose and unpredictable. The solid 1-1/4" 4140 chromoly steel bar ties everything together for a more balanced, controlled ride. With 3 adjustment holes, you can fine-tune stiffness to match your setup and driving style. The added stability makes turns and quick maneuvers more confident and predictable.
Crosswinds and passing trucks don’t have to push you around. This rear anti-sway bar minimizes side-to-side movement so you stay planted and in your lane. It keeps the ride level even on uneven pavement and when cargo shifts. The result is a smoother highway drive that takes less effort to keep straight.
Long days behind the wheel are easier when the vehicle isn’t fighting you. By cutting down on body roll and sway, this setup reduces the steering corrections you need to make on the road. That means you arrive feeling more relaxed, not worn out from constantly keeping things centered.
The polyurethane bushings resist oil, gasoline, and ozone, so they don’t wear out or squash down like rubber. That means less give in the system and consistent support over time. The bar’s silver vein hammer-tone powder coat and the black-coated brackets and end links add durable corrosion resistance that looks good and holds up for years.
No drilling needed—this setup bolts right on with the included zinc-plated hardware, clear instructions, and bushing lubricant. It’s a clean, simple install with everything in the box to get you back on the road with better stability.

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.

it took out some of the body roll in the wind
Must have for towing! Major difference over stock. Worth every dollar! Should have bought this for my ram 2500 a long time ago
478000 miles ago to be exact
Have a Lance 865 and went from timbrens to airbags. Ride got better but huge sway difference from the two. The sway bar is worth every penny. You get the initial sway and you feel the dampen right away. Excellent upgrade!
Haven't towed with it yet but install was easy
Deliver was quick, packed well, installed easily. I recommend Etrailer for your needs. Great company with great communication and follow up.
easy diy install. sway bar was heavy duty and worked like I hoped it would with my truck camper.
Fantastic upgrade to the inadequate stock sway bar. Eliminated the carnival ride's swaying motion immediately. I chose the stiffest setting right off the bat with no regrets.
Instructions were a little bit confusing at first. Read through 2 times after that it was a breeze. In all about a hour to remove and install. Works like a champ. Was put on a 2021 Ram 2500 with small pop up camper. All the side to side is gone
This swaybar was noticeably thicker than the stock bars. It was not hard to install. Had a issue with a bushing but customer service was spot on and immediately corrected the issue. The sway bar made all the difference on my Ram 2500 pulling a Momentum 31G toy hauler. This trailer is a bumper pull BEAST! Instant reduction in sway and also installed the Timbren bump stops to complete the rear end transformation. Would definitely recommend this product!

Sounds like any sort of white knuckling has been eliminated with all the upgrading you did. Happy towing!
The TC swayed to a point where I wouldn’t use it long distances. Bought the Hellwig Swaybar and the Truck was 100% better. etrailer only took a few days to send it to me. Install was super easy.
Heavy duty. Instructions were not great at explaining how to put together bushings. Once that was figured out, the install went pretty quick and straight forward. I do notice a more firm planted feeling when cornering.
This product is no gimmick, it really works and the factory support team is knowledgeable and succinct. Recommend
Thanks for the speedy shipment, now I can cure the tail sway in my ram 2500, already have front installed.
Missing part upon delivery. No answer from customer service.
Made a big difference in stabilizing side to side rocking.
Made a huge difference on my powerwagon with a fourwheel camper. The factory offroad suspension made it sway badly but this hellwig cured the issue. Must have, well made, etrailer rocks! I tried airbags first and they didn’t take the unsafe sway out, buy a hellwig!
Do you have a question about this Anti-Sway Bar?

That's awesome, Darrin! I bet the Carnival takes turns a lot better than it did before.
