I have a 99 suburban 2500 7.4
I currently use air shocks to help level out my suburban..when loaded with my trailer.
works ok...but,
I was wondering has anyone installed air life bags in the rear?
how difficult was it to install? and is it really worth the money?

What kind of trailer are you pulling? :eek7:
Max tongue weight really shouldn't exceed 1000lbs depending on your hitch. If you find your rig is sagging when towing you probably have some weak springs. You'd be better off just checking/replacing your leaf springs they might be bent from the previous owner overloading.

Sorry, I don't know anyone who's used the air bags.
