Video Transcript for Review of Hellwig Anti-Sway Bars - Rear Anti Sway Bar 1-1/2 Inch - HE43BR

Hi, everybody, Andy here with etrailer. Let's tale a quick look at this Hellwig Rear Anti-Sway Bar. Now this anti-way bar has been designed to fit your 2019 Forest River Forrester Motorhome Sprinter 3500 Class C and then your 2014 to 2018 Mercedes-Benz Sprinter 3500, the Cargo Van or the Class C. Non custom fit parts such as this bar I do recommend taking advantage of our vehicle fit guide here at etrailer. Just enter the year, make and model of your vehicle and answer any other questions that it might have for you and our pick guide will do the work confirming that this will work for you or maybe we've got something else that will work for you if this particular one will not work for you. Now this is all about making your vehicle feel more stable and easier to control, especially when you're driving something heavy or dealing with uneven conditions this is going to significantly reduce that side to side sway so you're vehicle's gonna feel more planted when you're turning, changing lanes or making quick maneuvers.

Even on rough or uneven roads this is gonna help keep everything level which is gonna make the drive smoother and more predictable. And one of the big benefits people notice is how much less effort it takes to keep your vehicle tracking straight. This is gonna cut down on the effects of crosswinds, passing trucks and shifting cargo which means you're not gonna be constantly correcting your steering. That's gonna lead to less driver fatigue and especially on those longer trips. Now from a durability standpoint, this is built to last, this uses polyurethane bushing, instead of rubber, so there's gonna be less wear over time and less give in the suspension.

That means better support and longer service life. Even when exposed to oil, gasoline or ozone. And the sway bar itself is made from thick 4140 Chromoly steel for strength and it has a corrosion resistant powder coat finish that's gonna protect it from the elements. And so installation is gonna be pretty straight forward it doesn't require any major modifications. It does have the little bit of hardware that you have here, but this is going to use your existing vehicle hardware and end link so that's really gonna make this a simple upgrade for you.

Instructions are included to walk you through that installation process. And the sway bar at the diameter of the sway bar is one and a half inches which is going to give you the stiffness needed to noticeably improve stability without making your ride overly harsh. So overall, this is gonna be a solid upgrade if you want better control, more confidence behind the wheel and overall a more comfortable driving experience. If you happen to have any other questions, whether it's about this or anything else that we have here at etrailer, don't hesitate to reach out to us we wanna make sure you're getting exactly what you need. Well, again my name is Andy, thank you for joining me.

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.

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!

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.

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! : )

It wasn't too hard to install yourself and it does make a difference with the sway

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).
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 $.

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.
