Alright, what bags for our truck will provide a lift?

Boss air suspension, Load assist for our trucks will.
Another forum user said at 10psi they lifted the back of his truck 1.5" And that's with no weight in the bed of his truck.

So just keeping them with a few psi will give you a small amount of lift. And I think that's way better to use rather than a spacer. Cause you can decide if you need a 1/4 - 3/4" of lift with having minimal effects on ride quality. Plus if you have to tow or haul anything in your bed, you're already set up for a better than stock ride.
If you are looking for a small amount of lift and do any towing or hauling, thats the way to go. But using a spacer in the rear, the front, or even using Bilstein shocks to lift the front of your truck is a inexpensive, cheap way of going higher. It provides nothing else other than a lift.

************* In my opinion of course!

Yes, that is correct. They're not designed to provide lift.

But they do recommend you always keep them inflated with at least some air in them. And I think if you were to ask the manufacturer if its ok to keep less than 10psi in the bags they would say its fine.

If its harmless to use a 1" coil spacer, what would be the harm of keeping air in the airbags to provide less than a inch of lift??

The air in the bags prevents them from collapsing - not to lift the rear of your truck.

We all know they are not designed to lift the back. But guess what they still do.

Always fun to read these posts..........

Both type air bags will lift the rear to some extent but one will lift more based on concept and design.

Air bags INSIDE the coils primarily keep the coils from compressing by exerting force against the coils (outward, not up and down. Also why they "float" and are not attached to anything) , basically using force/friction to restrict movemement. This is why these type bags instruct you to inflate the bags BEFORE you place a heavy load on them. They aren't meant to "push the load up" so to speak.

Bags on the outside, the ones that replace or go where the bumpstops are located, only come into play when the spring compresses to a point that the inflated pressure of the bag is sufficient enough to "impact" the load. By design, these type bags will generally "lift" the rear higher without any load..........

I'm sure it can be explained better
