In the front I went from roughly 36 5/8 and 36 7/8 to 38 1/2 and 38 5/8, so less than 2 inches. The rear went from 38 9/16 and 38 15/16 to 39 1/2 on both sides, so just under an inch.
I have the Outdoorsman so mine may have been a little higher than yours to start with and I also have the factory fender flares which may account for the 1/2 inch difference in our measurements (38.5 vs 39), it looks like we haver the same size tires as well. I think I read a time or two in the past that the Outdoorsman is 0.7 inches higher than other models and that a level kit would net a little less height but I guess I always wanted that to be false. If you got 2.75 and I got right around 2 then that sounds about right. Eventually when I switch to 285/75s I'll see if I want to move to the 2nd ring in the front. I only put 3 to 5k miles a year on my truck lately with most of that hauling camping, kayaking, and biking gear on trips so it may be a little while before I wear these tires out, I have maybe 12k miles on them right now and they were put on in March of 2019.
