I didn't measure it, but I'd call it 2-1/2 to 3 inches. Keep in mind that the old axles were flat dead, so part of that is due to new axles and part is due to the 32 degree lift.
I'm on the road right now, and we have noticed that things inside the coach don't bounce around nearly as much now.
I posted before and after pix on the Airstream addicts Facebook group.
