Features to know about

Tighter Handling Under Load: Adjustable 1" Chromoly Rear Sway Bar

Nothing settles a top-heavy or loaded rig like a solid rear sway bar. This one uses a 1"-diameter 4140 chromoly steel bar that ties the rear axle to the chassis for a big cut in side-to-side movement. Three adjustment holes let you fine-tune stiffness for the balance you want between comfort and control. It keeps the ride level through turns and quick maneuvers, even when the road gets uneven or the load shifts.

Confident Highway Driving: Reduced Sway in Crosswinds and Traffic

Long highway stretches or windy days don’t have to mean constant steering corrections. By minimizing sway and body roll, this adjustable bar steadies the vehicle against gusts, passing trucks, and uneven pavement. The result is a more predictable feel and less fatigue on long drives because you’re not fighting the wheel to stay on line.

Built for Strength and Longevity: 4140 Chromoly and Polyurethane Bushings

This setup isn’t built with soft rubber or mild steel. The bar itself is thick 4140 chromoly for exceptional strength and consistent performance, while polyurethane bushings resist oil, gas, and ozone so they don’t wear out or squish over time. Less give in the system means firmer, more reliable handling mile after mile.

Straightforward Installation: Bolt-On Hardware and No Drilling

You don’t have to tear into the frame to add stability. The included zinc-plated mounting hardware, brackets, and bushing lube make it a clean bolt-on job with no drilling required. The bar fits setups with 0" to 2" lifts, and the corrosion-resistant silver vein hammer tone finish on the bar with black powder-coated hardware keeps everything looking sharp and protected.

Video Transcript for How to Set Up Your Hellwig Adjustable Rear Anti-Sway Bar on a 2020 Ford F-150

Ian with etrailer here. Today we're gonna be looking at the Hellwig rear sway bar on our 2020 Ford F-150. Let's get into a couple features and then that install. So this rear sway bar is not a replacement like we've done for the front, but this is a add-on for the rear of this vehicle, giving it more stability going down the road. That way if you are towing, or you happen to have a heavy load in the bed, it's really gonna just brace that rear end of the vehicle like it should. I wanted to mention as far as the look on this, it's got a great finish visually, but these pits on the finish actually serve a purpose as well.

You'll see there's grease inside the bushings, and that those pits are gonna allow a spot for that grease to live, opposed to your factory bars, which are not gonna have any pitting. And then the grease wears out causing squeaks and noise, and other issues like premature wear. Another great feature of the Hellwig sway bar is the adjustability. So you'll see that it does have a threaded rod to be able to adjust our height up and down to get our most level position for the bar, which we're gonna be looking for. And then we do have these three positions here, which are gonna be our tension positions, depending on what type of ride we'd like.

If we've got a heavier load, of course we'll have it in the heaviest position. And then if we're just driving around the city for a long period of time, we're just gonna have it in the lightest position, like we do for this neighbor. So I will say with the installation, it's not all that bad. We do have to run a couple plates that are gonna go inside of the frame, so that's about as hard as it gets. But all that being said, if you don't wanna try to tackle this on your own after watching the video, please do check out our dealer locator.

We'd be happy to get you a trained professional that can install this for you. But for all those DIYers, let's go ahead and hop into that install. So we're gonna start by taking our plate that's attached to the wire here. This is gonna act as our backing plate for the front clevis we're gonna be putting on. So we'll come up to this hole.

There's one above the bump stops, but you're gonna find one just in front of that, and that's where we're gonna insert into, and we're trying to line those holes, one of the two up with this hole here that's in line with our shock bracket. So that may take just a little adjustment. You'll have to fiddle with it until you've got at least one of the two holes on that plate lined up. I got it somewhat lined up. Just to kind of help bring that into place, I've grabbed the bolt that's gonna be going into it anyways, put a couple threads on there, and just pulled that into a better position. We're gonna raise up this clevis, and then we do want that facing with our bolt holes towards the side of the vehicle as much as possible. And we will just feed that through to the plate. And again, you may just have to keep adjusting as you go along, 'cause that little plate will wanna dance inside of the frame. And then once we've got that into place again, we're just gonna wanna try to have that as lined up with the rear of the vehicle as possible. And then we're gonna torque to the specs shown in the instruction manual. We need to build the end links. Both of 'em are gonna be built the exact same way. We're gonna start with our threaded end, and we'll be adding on the larger nut that comes with the kit that's gonna work as our retainer on that link. And we'll just get that down as close to the bottom about an inch away. And that should be more than enough. And we're gonna thread on the other end of our link here, and we'll just go all the way down to where we've got the retaining nut. Then we'll need to push in these rubber bushings first. So easiest thing to do is just kind of get those set in place, and then you can use either a vise or good pair of channel locks to do the exact same thing. And we'll wanna evenly press that in, nice and slow. Then if you need to, once you've got that started, you can either push it in by hand, or you could tap it against something, and that'll finish it out and center it back up. We're gonna have two of these insert sleeves that will go in the center of the bushing. Those you can just get started by hand like that. And then same situation, either that pair of channel locks or vise grips to get that pressed in. And we'll repeat that on the other side as well. Now we'll take the threaded end of our link here. We're gonna run this silver bolt through that. It may be a little tricky to get that in there first. Just kind of give it a good wedge, and we're gonna come through the backside with the bolt, and then add the lock washer on the outside. We're gonna leave all that loose, just so we can get everything else up. There's gonna be three holes in the ends where the link can attach to. The outer ones are gonna be your most stiff position, the inner, your least. So what we're gonna do is just go with the least for now per the neighbor's request, and we'll slide the bolt with washer through the outside, and then going onto the bar with another washer on that inside edge. And last, the nut. I'm gonna leave all this loose while we get the rest of it hung. Going to be putting the D-rings onto the sway bar before hanging it all the way up. So we'll just need to lubricate the inside. There is a split that's gonna allow us to go over the bar, but we'll start with that lubricant, and we'll spread that out evenly. And we're gonna take that bushing, and just get it over our outside edge loop here. So you can see there's one bend, and then our second bend here. So it'll be on that second one, and we will add the D-ring bracket as well. Then we're gonna follow the instructions as far as getting the U-bolts up here. We're going to have this run up in between the bracket, 'cause I found to be able to get that to line up. We're pretty much at the very edge of that bend. And then we will be adding our bracket here with the V notch towards the axle. And then this is gonna sit right below that, and we'll add a washer, and then a nut to the end of each of the U-bolt studs. We're gonna come to the passenger side now, and do the exact same thing we did on the driver. And then we're gonna wanna torque these down to the specification shown in the instruction manual. What we'll wanna do is just kind of alternate these between the two until we've got nice, even pressure, and then that torque spec. And then we're gonna come through to the end links, and get those torqued to the specification shown in the instruction manual, both top and bottom. And we will be repeating on both sides. That's gonna do it for our look at and installation of the Hellwig rear sway bar on our 2020 Ford F-150. My name's Ian with etrailer. Appreciate you watching.

I haven't installed this kit yet, but the quality looks very decent and quality. The kit is complete. The only issue is that I have an 8.8 axle, but the brackets are for a 9.75, however, I think that if I tighten everything down correctly, it should install just fine. Thanks.

Bought to help with a pop-up slide-in camper. Install went pretty good after Hellwig overnighted D bushings to replace wrong size bushings sent with the sway bar. The next items missing were (2) 1/2" locknuts for the axel brackets. Ran down to Ace hardware for those, not wanting to wait another day. I wonder who checks the kits before shipping?
So install went OK. Drove yesterday and really can't say the drive was noticeably different. Will try adjusting the bar to see if it does stiffen things up. Also have ordered new shocks to see if that helps. Response from e-trailer and Hellwig was good. Thanks.

Sorry to hear about the missing and incorrect parts, Joseph. Surprised you couldn't tell the difference after the install. I think doing some adjustments will get it engaging more and you will notice. Especially in the corners. Did you have the camper in when you tested it out?

by:

Overall is a good product. The bar itself is good quality and the parts are good. So far so good on the sway bar. Makes my truck ride better and feel more controlled. If you’re installing this on a 2020+ silverado 2500, the way this is hung from the frame is difficult. Theres a part of assembly the requires a metal plate tack welded to a wire that has to go inside the frame of the truck. I spent about an hour and a half to install it but I ran through the install process about four times. When you push that plate into the frame you really have no control where it lands. I ended up using a small metal pick to pull the plate to the required location. Once there, I used a long screw driver to hold the plate down while I set the bolt in. I honestly think had I not used the screwdriver this plate would have never gone on. Theres a small hole right above the mounting hole to push the plate down. Theres also welded bolts that GM put under the rear shocks that have no threads and thats where the brackets go. It says to drill them out and use the provided bolts but I just went to my local auto shop and picked up bolts that fit the welded bolts. Seemed to work just fine. Once these were overcome, install was straight forward and went on pretty quick. Four stars just because the mounting is difficult compared to other products HellWig make.

I really like the fitment and performance of the product. I have installed a Hellwig anti-sway bar on my last 3 trucks and always feel an improvement the way the truck handles cornering and when pulling a load, especially when there is a cross wind.

Thanks for your review, Matt! It says a lot that this is the third truck you've equipped with a Hellwig anti-sway bar. We're glad to hear you've continued to see improvements in handling, especially when cornering, towing, and dealing with crosswinds. It really is amazing the difference an upgraded sway bar makes!

Application was a 2015 Tacoma.
Install was easy enough. For others that may read this, it would be wise your spare tire to make certain there is no interference with the sway bar.
I have a 33" spare tire, I had to make new adjustments after I tried to put spare tire back up. Infact, May be wise if you have room to leave the spare tire in and work accordingly.

The install is new, sediments are a bit subjective as to difference. But driving while unloaded I get a bit surprised that the Tacoma tracked really well around a curve. Folks at E- Trailer were great.
by:
When lifting a jeep, body roll, increases due to the mechanical advantage of the chassis over the factory sway bars. This larger and adjustable sway bar helps correct that issue and allows for fine-tuning to driver preference.

Fairly easy installation and I’m not a mechanic. For the price of a professional installation, I was able to purchase all necessary tools and still save money.

Easy installation

Haven’t towed with i
t yet so not sure how much it will help the sway with a 31ft travel trailer.
by:
Upon receiving the box which came on time, I took all the pieces out to make sure I got everything I needed. Two 7/16-20 21/4 inch bolts were missing. I called Hellwig customer support and they promptly sent the replacements. The bolts were not packed with the rest of the installation materials. I also want to say that the top of the box was torn open. Many of the heavy staples had come out. The box inside was torn open and a couple of pieces had slipped out. Also someone trampled over the box because there were boot marks all around the box. Very poor quality in delivery service even though it came on time. Important parts could have fallen out and delayed installation. Not very good delivery service.

For the second time in a row ordering from etrailer, either parts were missing from my order or shipping was a problem. The sway bar works fine, once I got the right parts to install it.
by:
This is a heavy duty sway bar. The installation was straight forward and simple.
I used the middle adjustment hole as I wanted to tow an RV. I took it on an initial test drive. This unit completely got rid of the body roll. Well please and know that a little hint, wear gloves when apply the lubricant as that is gooey!
by:
Great quality part at a decent price and a quick delivery on my order. Will definitely use etrailer again!!

2026 dodge Ram Pickup
I installed the 1 inch adjustable anti-sway bar on my 2026 ram rebel and it works great. Even though I only put it on the least aggressive setting, the truck handle so much better through the turns now that it did before. I will test it to a 7000 pound trailer in the next couple weeks. . Definitely recommend!. Also, E trailers Service was super friendly and super fast. I received the Hellwig antisway bar in two days after ordering
by:
It was just what I needed to fix the top heavy sway on my truck camper!
by:
2017 dodge Ram Pickup
I put a really heavy truck camper on my 2017 ram 2500 6.7 hemi and it took turns ok but it would rock side to side a couple times over bumps and uneven roads. I wasn't sure if this would make a difference because the factory one looked pretty big but it made a huge difference. This and airbags are a must for heavy loads.
I also go it a day sooner then I thought.
Very happy.

Solid, sturdy and well built anti-sway bar. I installed it on my 2024 Ford F150 without removing the spare tire and the install went fairly easy. It did take some time as I was.doing it myself. An extra set of hands would make it a bit easier. Love how solid my truck feels and drives now.
by:
I only recently learned my 2023 1500 ram, which includes the tow package, uses a hollow sway bar. Disappointed in Ram.
Using the outer most setting made a significant difference over the original equipment. In fact the difference is so noticeable I’m going to fireplace the front sway bar as well.
by:
Nice product However the instructions are terrible! The written instructions have been copied so many times they are basically unusable. The accompanying video left out many important details causing a much longer instal time than necessary. We had to uninstall more than once do to correct the incomplete installation video.
by:
Ashley was wonderful to work with on my order fast shipping tech was great help the rear sway bar was a up grade from stock unit by far great Quality easy to install Hellwig makes a awesome product l will buy more product’s from e trailer in the future
by:
Great upgrade for my truck and fifth wheel.
by:
2019 Ram 1500 Classic
Easy installation on Ram 1500 classic 2wd. Took about 1.5 hrs including the test drive. Didn't have to jack the truck up, just crawled under and bolted it in.

Thanks to eTrailer support for pointing me to the right one for my truck.
by:
2021 Ram 1500
Easy install and definitely stiffer cornering. Can't wait to try with trailer.
by:
It's an amazing improvement over the stock sway bar. I don't see any need to use the outer attachment point. It gives you plenty of bar at the lower setting. The mounting hardware and bushings are much better than the stock attachment bracket and bushings. The truck stays flat in a curve. Bottom line: Just buy it!
