I have been trying to figure this out as well. I have a 87 3/4 ton 2wd Suburban that seems the rear sags a little too.
I always figured the previous owner used it for a lot of towing and over time the rear springs have sagged a little.
I was always wondering, if I replaced the springs with one ton springs or a spring with a higher weight limit would is raise the rear a little to get rid of the sag? Or if I went with stock springs would it lift the rear a little?
