Suspension upgrade??

don't ! try torklift uppers first

Stableloads will help with sway more than bags or bumpstops. I'd start with those and see if you like the results. You can make your own out of wood to simulate them and if you like how it goes buy or make the real thing.

And I'm talking about lowers, make that lower overload work harder than the upper overload, you will see a larger effect setup that way.

I'm a big fan of the Torklift Stableloads. They won't ever spring a leak, you never have to keep 5lbs of air in them, they'll never pop.

They will help a little with sway, but that is not their intent. Their intent to to help level out your truck by engaging the overloads sooner. By doing so, it helps with sway a small amount.

But..

Nothing helps with sway more than a sway bar. I prefer Roadmaster, they're much bigger and beefier than Hellwig. I had them on the front and rear of my previous F350 DRW, and it was night and day for sway control.

get a Roadmaster anti-sway bar. Added one to my rig, worked wonders for sway. In addition to Rancho 9000 adjustable shocks.

On my 2006 Dodge RAM 2500 CTD I had too much sway loaded. First I tried Firestone Ride Rite airbags - big mistake (should have read the forum first). Then I installed a Big Wig Sway Bar (1-5/16" diameter) which helped but still was bad due to the "added" sway caused by the airbags (should have read the forum first). Then I installed lower Stableloads and fixed all of it. Wish I would have read the forums first. BTW they were the easiest (and cheapest) install out of all three.

Now all of that said -- if your 2016 RAM 3500 SRW is anything like my 2015 RAM 3500 SRW (I'm guessing it's identical), there's NO gap (or extremely small) between the overload spring and the regular spring pack. I don't know how I'd even get the lower Stableload to slide between the OL and the spring pack. Heck, there's not even enough room for the shaved down bolt head to fit in there. I'd call Torklift and ask them if they will fit or do any good on our late model RAM 3500 SRW trucks. I kept my SL's from my 2006 RAM but I can't see how they could fit (or do much good) on the 2015 RAM.

Yeah it's tight between the lower overload and the spring pack. Just eyeballing it 3/16" at most. The fronts have maybe 1/4".
The more I read, it will likely not be the bags. Either a sway bar, the StableLoads, or nothing.
When I was going to Broken Bow Oklahoma recently, I remembered the curves on HWY 259 near Idabell. About 1983 I thought I was going to flip my F250 with a cabover on it. Counter steering into the wind with a very acute lean. Oncoming traffic riding their shoulder, almost as scared as I was.
I'll call Torklift.

I have a 2015 Ram 3500 SRW like yours and have been really impressed with Timbren's as my only suspension mod. My Lance 1040 puts the rear axle at 7500lbs, and the Timbren's are rock solid. I tried the stock suspension before adding the Timbren's and the camper really squatted the rear springs. Timbren's fixed the squat and sway.

to install lowers I jacked the pressure off rear tires using the the hitch as the lifting point this opened a gap between the spring pack and the lower over load

I used to have the Air-Lift Super bags. Plumbed them with separate lines. If plumbed together they have a tendency to rock. I modified the fittings on an old Buick air compressor for ride leveling and it worked great, never a problem. I had it mounted in the rear fender well in front and above the tire, talk about a rough environment. I could adjust the pressure on the fly, only way to go. Used it for over 10 yrs, my son still uses it.

I'm already a bit nose high with the 5th. If the rear of the truck doesn't sag I will be even more nose high.

Am I missing something or does that make no sense?
Are those of you claiming to have sway issues caused by air bags plumbing your left and right bags separately? I did and mine drives great.

Those blocks that engage your overload springs sooner work fine but try not to spill your coffee over the next bump in the road when your truck isn't loaded!
