Final height will vary depending on what size of tires you are running. I roll around with it set at about 5" and it fits in most garages with my 295 winter tires but won't with my 35's.
Sounds good, I wasn't crazy about buying a truck with a lift, because I wanted a 4" tough country, just enough so I could fit 305's with -12mm backspacing. Sounds like this should be about equivelent.
