Features to know about

More Control on the Highway: Solid 1-5/16" Chromoly Bar Keeps You Level

Big loads or tall rigs can make every gust of wind feel like a fight to stay straight. The 1-5/16" solid 4140 chromoly steel bar ties the rear axle to the frame to resist side-to-side movement. That takes out the “tail wag” and keeps the ride level through crosswinds, passing traffic, and uneven pavement. With less sway, you hold your line with confidence and the truck feels planted at speed.

Better Handling Through Turns: Rear Bar Tightens Up Response

Long wheelbases or heavy campers can make corners feel loose. This rear anti-sway bar balances weight transfer so the body stays flatter when you turn. The result is more predictable handling in sharp curves and quick lane changes. You can steer smoothly instead of constantly correcting, for a drive that feels composed instead of top-heavy.

Less Fatigue on Long Drives: Stable, Predictable Ride

When your setup stays steady, you don’t have to fight the wheel all day. By minimizing lean and side-to-side motion, the bar reduces the small corrections that wear you out over hours on the road. The steering stays calm even when the wind kicks up or the road surface changes, so you stay relaxed and in control from start to finish.

Long-Term Strength: Poly Bushings and Powder-Coated Steel

This setup is built for the long haul. Polyurethane bushings stand up to oil, gasoline, and ozone without softening or cracking, so they keep their shape and support. The sway bar itself has a corrosion-resistant silver vein hammer tone powder coat, and the brackets and end links get a black powder coat to match. Everything stays solid and good-looking mile after mile.

Straightforward Install: Mounting Hardware and Lube Included

There’s no drilling needed to bolt it up. The kit comes with heavy-gauge, zinc-plated hardware, detailed instructions, and bushing lubricant. With basic tools, you can get it mounted and ready without special equipment, then hit the road to feel how much steadier it drives.

A few modifications. Had to cut/grind off break line brackets that were in the way of the brackets that attach to the axle and over the lip of the “pumpkin”. I have a Torklift Superhitch Magnum 30k mounted on the truck. The bracket that came with the kit were not used. I had to line the rod ends to the Torklift bracket and drill a hole to bolt them together. Even on the dually, it removed quite a bit of the side to side sway that you get from the tall slide in bed campers. I have an Arctic Fox which weighs around 4,000# when fully loaded.
by:
I just installed this on a Ram 3500 drw. First, go through all of the piece to both familiarize and see if all are there. A couple of important bushings were missing in mine, but Hellwig sent them to me very quickly. A parts list would have been nice. The fit on some of the pieces can be challenging, and my U-bolts were shorter than they should have been. It is what it is, designed for a truck that wasn't necessarily designed to have one, and the installation is consistent with that.
by:
My truck was a little different from the instructions so I called customer support and they knew exactly what I needed to do. The fit was perfect
Thanks etrailer!

Packageing really sucks.
by:
Now that I have two of these installed, I love them. What I did not love was on one unit, Hellwig had welded a bolt tab on one of the mounting brackets on the wrong side/wrong location and in both kits, the holes in the mounting plate did not align with the U-bolt that goes around the axle.

Good product. Etrailer support is outstanding.

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!

Installation was simple and easy, parts for exactly as they should except I had to cut some bolts on my air bags that were extending too long. That was not a problem of the anti-sway bar, just a modification I needed to make on my air bag bolt lengths. Otherwise it was a pretty easy install. I preassembled everything in about 15 minutes, laid the parts on either side of the rear end and it took about an hour to complete the install. Ride is fine on the stiffest level and it made a big difference in stability around corners and over rough terrain.

This is one of the best modifications I have made to my F350 carrying an Arctic Fox 990. Totally improved the ride on corners and rough roads.

@Wayne That's awesome to hear! Where are you usually towing your Arctic Fox to?

I placed my order and it shipped and arrived quickly. This item fit well. I was pleased that I could install it without having to remove the fuel tank. I have a 1999 Ford F350 4WD diesel SRW truck. I installed airbags but was still disappointed in the sway with my Lance 1062 camper. This sway bar made a noticeable difference. My truck did not have a factory installed sway bar.
I highly recommend this product.

This Hellwig Big Wig #7320 Anti sway Bar for our 2022 Ford F-250 CrewCab 4x4 fit perfectly! It is SIGNIFICANTLY more robust than the stock OEM Anti sway bar installed as part of a Camper/Towing package that Ford installs. We are using it this weekend to see how much less sway/tip, or rate of settling occurs compared to the original.
by:
So happy to receive this item after the first box showed up empty with UPS! This box can in open but all utensils I believe were still in box thank goodness. UPS is not five star but this company is especially Paula who handled our order. Made her aware of the UPS alert that box was empty and she had a new shipment to us within hours and it still arrived the day before the installation appointment! This is the best company and will order from then again and again when we need items. Why??? Because the customer service is OUTSTANDING! Thank you!!!!!

Thanks for the great review Joseph, even though your order was not the greatest experience, and realizing that we are not UPS. Paula is great! I sent your review over to her and she appreciates your kind words. On a different note, I have the Hellwig on our 2024 Silverado 1500, made a huge difference with that body roll! You will definitely notice a great difference when you get it installed.

I purchased the Big Wig sway bar set, front and rear (1-5/16" diameter) for my 2020 F350 after considering alternatives (Timbren, RAS). I am very happy with this new setup. Together the two anti-sway bars eliminated several handling issues I worked to resolve over two years of replacing worn components. My truck has over 205,000 miles and now handles better than new. The larger front sway bar from Hellwig and new bushings eliminated bump-steer and most of the slack in my steering. I previously replaced the end-links, all of the ball joints and tie-rod ends, shocks and steering stabilizer. Each made improvement tightening the steering but did not meet my expectations for improving control. The rear sway bar keeps the truck level with a load and has helps control the vehicle and trailer in cross winds. I have two large box trailers I tow, one is a 38' travel trailer, the other a 26' car hauler. I now have much more control and confidence when towing. Ford should ship any tucks that aren't a tremor or a raptor with a rear sway bar.

One word of caution: double, and triple check your Hellwig kit for fitment. I originally ordered the wrong kit based on a lack of detail between 4x4 and 2WD models. Kudos to etrailer, as they made it right after realizing the distinction wasn't easily found. If you have the correct kit, the rear sway bar sits level.

Wow, 205,000 miles and handling better than new. That is the kind of glow-up we love to hear about Greg! It sounds like you really dialed in your setup piece by piece, and it paid off in a big way. Pairing the Timbren and RAS with upgraded sway bars is a serious combination, especially for hauling trailers like yours. That added stability and confidence in crosswinds makes a big difference on long trips. We also appreciate you calling out the fitment note on the Hellwig kit. That is very helpful for others getting set up. Glad our team could help get you squared away there. So where are you off to for the next adventure?

by:
Removal of the old sway bar was more difficult than installing this Hellwig Big Wig Assy. Thank you Ford for no access to the nut between the frame and fuel tank. Everything went together smoothly. Delivery from etrailer was on time as promised.
My only criticism of the product was that the instructions were excellent (not so with the pictures provided) right up to the attachment of the adjustable arms to the Big Wig bar. What are the effects to the ride of the truck if you go with which hole. How long or short should the adjustable arms be?

The ride of my 3/4 ton truck has changed drastically.. Rock solid ride, semi trucks no longer toss me around when they go by, no longer do I feel like the truck will roll over when I corner. I carry a 2000 pound camper in the bed of this truck.

No problem. Completely satisfied

Works fine. Broke off a bolt during installation of one of the lower brackets. The Ford factory lock nuts grip extremely tightly making installing the Hellwig bolts difficult.
The geometry could be better. Not in love with how low the bar hangs in the rear when the truck is not loaded. Maybe if I ever need to land the truck on an aircraft carrier it will come in handy.

I had a great experience with etrailer. Got my sway bar delivered proply but when it was delivered to my house the box was wide open. Luckily all parts were there. It was no fault with etrailer, just with all the ups handling.

Glad to hear it all arrived safe and sound! We'd love to know what you think once you get some time to use the new Hellwig. [I love your porch, by the way! The brick and potted flowers are charming :)]

Installed on my 2022 F250 Tremor. Removed almost all of the excessive sway while hauling my cab over. Installation instructions are very clear and easy to follow. Installed in my driveway with basic hand tools in about 1.5 hours. By myself.

@BrookeM yes I grew up working on and helping build cars. My dad used to road race Datsun 1200’s and 510’s in the 70’s and had a circle track car when I was growing up. I’ve owned and modified a bunch of different cars (mostly Datsun 510’s and 240z’s) and motorcycles over the years. This was relatively easy due to all the extra room to work/ install the parts. I’m absolutely amazed at how well all 3 of the mods I did worked. I was thinking that I might also need airbags, but now that I’ve installed everything and driven around with the cab over on my truck, I don’t think it needs them at all. Thanks for the great service. I’ll definitely be shopping with y’all again. Cheers

@Chris Wow, what a childhood - that is super cool. Those Datsuns are awesome little cars! Living like Dom Toretto before it was cool. Keep living life a quarter-mile at a time!
by:
It took me maybe an hour and a half to install and adjust. No more side-to-side sway when passing big rigs or encountering them from the other direction. Really makes for a comfortable, more relaxed driving experience. I would definitely add this to any truck hauling a slide in camper or hauling a heavy load.

Went on smooth on my 2024 F250 6.7HO. Now the ride is more stable. I installed Sumo springs in the front also. A big difference in stability now. Rides a little firmer but no sway.
