Believe it or not this is a tough country 2" lift.
I don't remember the tire size right off hand (and the Sub is sitting in the shop at work) but the tires are not less then 31".
To me, it looks like a 4" lift but I checked the part numbers on the springs and checked correct for a 2" lift.
edit to add, I have experience no sagging with my springs. I purchased their premium shocks but still consider the ride harsh over sharp bumps. I wonder if Bilsteins would have been a better choice.
