first you cant do a soa lift since you dont have leaf springs and also the GCs are unibodies so you cant do a body lift. i have the same setup as texaszj1 and i live the kit. i am running 33s but would not go 35s with the kit. yeah you could hack alot to fit them, but i had to hack my front bumper just for 33s. i have not heard anything about the rockcrawler lift, so i cant tell you about it. all i know is it is a 7" long arm kit for 2k.
