Air helper springs, how to properly adjust?

[sledwrecker]

Hey folks,

I have an 02 F350. It was setup for a camper when I bought it with torquelift mounts and air helper springs (bags)

I'm about to drive from Idaho to Minnesota towing a 2,000ilb trailer with another 1,000 ilbs in the bed. I have absolutely no idea how to properly adjust the air springs. They do not have an onboard compressor (that I know of) but I followed the lines and there are standard air valves like on your rim that are mounted in the rear bumper. I assume I just add air but I don't know how much. Tomorrow I'll crawl under the truck and try to find a make / model number for the bags.

If its too stiff, let air out. If your truck is sagging too low, add air.

I've found that if you put enough air in bags to bring it just to top of springs that way the springs will still do some work. Like my truck I haul a 4100lb slide in camper. With my bags ill air them up till I'm just sitting on my overloads. That's just my way. If you wanted you could put all the weight on the bags but then it kind of defeats the purpose of a helper bag.

Both these^^^ responses sound good to me.

ive got the same setup as you have. ive got my firestones set at 60 psi. the truck sits level and just off the overloads. i recently got a tank and a compressor on here. just waiting for nice weather for driveway work.

I've never used my bags that were on my '01 when I bought it and with my car in my enclosed trailer it sits/rides/drives fine - even @ 80mph. Weight of the trailer and the car is approx 5500lbs, and sometimes we throw 2 quads in the front of the trailer in addition to a loaded roller tool box and gear for a weekend.

with only 1k in the bed and 2k behind the truck i wouldn't even consider air bags.
i've had about 2 tons in the back before and thought maybe some helpers would be nice.
