Expert Reply:
For your 2020 Ram 2500 with factory air ride, a great option to reduce rocking while towing a fifth wheel is the Hellwig Adjustable Big Wig Rear Anti-Sway Bar – 1-1/4" Diameter # HE87FR. This bar is a direct fit for your truck at factory ride height and installs with no drilling required.
The Big Wig is adjustable, so you can fine-tune how stiff the rear suspension feels depending on how much control you want while towing. It makes a noticeable improvement in side-to-side stability, especially with taller or heavier fifth wheels, and pairs well with the factory air suspension by limiting body roll without compromising ride quality when unloaded.
Just keep in mind this sway bar is designed for trucks that have not been lifted or lowered. If your suspension is stock, you’ll be good to go.

I installed the Hellwig Big Wig rear Anti-Sway Bar on our 2018 Ram 2500 (used the middle adjustment hole) in hopes of helping with severe sway when using our Palomino packpack 550 truck bed camper. Installation was easy and it totally eliminated the sway issue we were experiencing before installation! 100 % satisfied with this upgrade!

I added this swaybar to my 2018 2500. I have a truck camper that fits in the bed weighs about 2000 pounds between this swaybar and having to add airbag because I have a coil spring rear suspension. It made a night and day difference eliminated all sway back-and-forth, and all wanting to wander and drift.

Michael, I have a 2016 Ram 2500 with Auto Air Ride. I also have a Lance 820 Truck camper. I had a ton of sway with the weight of the camper, I removed the stock sway bar and went to the Hellwig Big wig. Install was super simple. The notice of the hellwig was immediate. I would recommend this sway bar to everyone. I do have the setting at its tightest because the Rams do not have any leaf springs or other options for the suspension. I am also thinking of adding larger bump stops to add extra support for sway. Let me know if you need anything else..

I have installed the 1-1/4” rear sway bar on a 2016 Ram It doesn’t have air ride, made a world of difference in towing the 5th wheel. Took me approximately 45 minutes to complete the job
