REAR AIR BAGS FOR RAM 3500 DUALLY

I have the Firestone airbags with the on board air compressor. Works like a champ. The pin weight of my fiver is 4000 lbs...

Yes, they will help the ride immensely by getting the truck off the overload springs. We have a 2001 Dodge dually pulling our toyhauler very similar to your weight. Without any air in the Firestone air bags the ride is awfully harsh. I've found that about 50 psi will lift the truck and the ride smooths out and makes for a much better ride.

I also installed the Dexter EZ Flex suspension on the toyhauler and that helped the toyhauler ride smoother. Both are worth the money. IMO of course.

I have a Chevy C4500 with a Link Air Ride suspension in the rear. The Link system uses large air bags with an automated load leveling system. My pin weight is about 3500lbs.

When I hit rough roads the ride does seem smoother than my old 3500 dually with overload springs. Not as pounding but more floating. However on big bumps I'm not sure if the air bags are any better. I seem to notice the big bumps now more than I did in my 3500.

Your best bet would be to try www.dieselplace.com forum for the dodge users group to see if anyone has added air bags.
