2022 3500 Drw rear spring question?

[Scvette]

So I ordered my truck with the rear air, then cancelled it a week later. Was confirmed it was cancelled by dealer! Ordered the Carli 2.5 leveling kit and have it in my garage. Got my build sheet yesterday and my truck has rear air… no biggie. So CJC off-road says I will probably have to get the 1” blocks for the airbags and leaf springs. There are 2 options for the leaf spring block. So my question is, the trucks with air, do they have the overload springs? Or is it the trucks without air have overload springs.
