Firestones for me. Manual fill separate lines. I ran mine to the storage space under the back seat. I lift the seat and platform, take the caps off and fill or remove air twice a year. 22 lbs for summer and hauling the 5th wheel. 5 lbs for winter.

last set of firestones I installed came with a "T" for plumbing both bags into one air up fitting which i installed adjacent to the rear license plate.

I see no need to have them filled separately and don't subscribe to that urban legend of the air transferring from one side to the other when cornering.

Two decades, two F250's, nary a problem.

I believe that the air transferring is real but whether that is good or bad depends on the application. If you have a high CG load like a fifth wheel camper or slide-in and need stability you don't want the air moving. Likewise if you need to level the truck side to side, like if you parked on of those rigs on a side slope and need to level the truck.

On the other hand, if you don't need lateral stability having them separate will make your ride rougher, increase lateral pitching on bumps and can cause traction issues on uneven ground.

Like said above, your application may not "need" bags plumbed separately, but there's nothing to subscribe to. It happens and it reduces stability if that is one's condition for adding airbags.

Since I always carry a bicycle pump and onboard air pumps are the weakest part of an air bag system...plus I saved some money.

I can see having onboard if you offroad and you air big balloon tires up and down multiple times in a day.

Airbags simply don't hold much air and are well within the pressure capability of a bike pump.

Ok, Val, I agree if you are altering tire pressure constantly. But my off-roading is very light duty.

I’d like to add airbags to my rear suspension on my Ram 2500 diesel to level my truck when I’m towing, but don’t really feel I need to be able to control them from the cab and don’t want to go through an expensive and involved installation of a full system with a permanent compressor. Any recommendations for airbags that can be inflated with an external compressor?


Got to ask what year is your Ram 2500 and what are you towing that you need bags?
My old 2001’Ram 2500 carried 2,700# of pin from a 5er and didn’t need bags.

I have the Firestone bags on my 2001 Cummins dually with a 3000 lb. pin weight and have the manual schraeder valves for each side. I put in about 50 psi for traveling and let it out when not towing. I carry a lightweight 5 gallon aluminum air bubble, and it works great for adding air to the bags. Fill it to 120 psi and it's good for 4-5 fills.

Never really felt the need for the cost and complexity of the onboard compressor.
