I have had airbags on my last two trucks, first was a 2002 duramax cc 2500 which I later switched the rear springs to 3500 springs which made a huge difference. I also have airlift 5000 airbags on my 2017 Silverado 3500 LB duramax and they serve a purpose. I leveled my front end by raising it about 2 inches, so when I hook up to the 310gk I add enough air to keep the truck level so my headlights aren't blinding oncoming traffic. Did they help the ride? I would say maybe, but my ride seems very firm with 50 psi on the airbags, and I actually think the truck rode better without them. Driving around empty I run the airbags at 5-10 psi and the rear of the truck is still overly stiff. I just replaced my factory Rancho 5000 shocks with some Fox shocks and unfortunately no improvement in ride. I usually have 60 gallons of fuel in my aux tank and that helps some, but empty the truck rides pretty harsh and is especially bad for whoever is riding in the back seats. I don't think it is a good idea to use the airbags to support a majority of the load since the airbags go inboard of the leaf springs at least on GM this gives more leverage outboard of the airbag to bend an axle tube. The leaf springs still need to support the majority of the weight. This could be a real issue with some of the 2020 up Fords that were found to have thin axle tubes that got recalled for more weld on the spring pads. Ideally if the truck needs a little bit of a lift, a 1 inch lift block would be better than using the airbags to keep the truck level by adding too much weight to the axle tube.

Well, FWIW, a HD one ton truck is going to ride harshly regardless of whether it has bags or not. It's just the nature of the beast. If it didn't ride harshly when empty, it wouldn't work to carry a heavy load.

I have a 2020 Denali 3500SRW Duramax, I don’t have a payload problem, but there is just more squat than I want. I went with the 7500lb airlift with the onboard wireless compressor. It’s simple to use and no more squat.

My guess is that airbags would definitely help with your 337RLS especially since you're towing with a 3/4 ton truck.
I have the Firestone Air Bags, no compressor, and only need to keep them set at about 30 PSI for an optimal ride on my 2006 Sierra 3500. I also have a rear stabilizer bar installed which is also a big help. I like having two separate fill valves to adjust as needed. I mounted my shrader valves where the license plate bolts were.Bill & Colleen ~ Schwenksville, Pa

There is generally no "best" (which is subjective... it varies for each person and vehicle); Whether or not it is worth the money is also subjective.
When I towed a TT, I did not have air bags, but before taking delivery of my 337RLS, I had a set of Air Lift 7500's installed (sans compressor) on my Ram (2017 Laramie 2500). They help to smooth the ride somewhat, even when unladen with ~10 psi in the bags. They also help to level the truck when towing. For what I paid for them, I found them worthwhile. When I upgrade/trade to a 3500, I am not sure if I will add air bags... will see what happens at that time. Another option on a new Ram would be the factory installed rear air suspension... more expensive, but probably more convenient. Of course, that cannot be added to an existing vehicle... the next best solution would be aftermarket (i.e., Air Lift or similar) air bags.

I have the basic Airlift 5000 and really like it. I originally had the 2 bags plumbed independently with 2 valves but found I was always pressurizing both the same. So I bought a T-fitting and now have only one valve. I use a bike pump to inflate to 35 psi after hitching. I feel it stabilizes the ride.
I would like to upgrade to an onboard compressor but when I looked at this a while back, those compressors couldn’t get to the 120 psi needed for my trailer tires. Seemed like an expensive upgrade for just the airbags when a bike pump works fine for me.2021 Solitude 310GK: Linen/DP windows/gen prep/slide toppers/king bed/EOH disc brakes/Cooper-H tires

I've used Firestone bags on my last truck ('09 f250) & the cages they were mounted on collapsed under the weight of a Lance slide in camper. Went to Airlift 5000 bags with no problem after that. No on board compressor, mounted the valves behind the fuel fill door.
I have Airlift with remote compressor on the dually in my signature now, the ride is not as harsh with the camper or the trailer. Manual inflators are still behind the fuel door in case of compressor failure.
They were easy installs even for a 65yo (at the time).Paul, Sue & Wonder Dog Zane
