Hi I have a 2001 grand cherokee limited 4.7 love it to death but it has 207000 on it so don't want to put to much into it cash wise. I want to fit some 31s or 33s on it and was wondering what sized lift I would need I was thinking a 2in for the 31s and it I did that what all would I have to do on top of the lift kit? (I run with a 87 k5 blazer with 31s and a factory 2inch lift so I'm trying to compete alittle for cheap)
