I've decided on a six inch lift and 33" or possibaly even 35"
for the ZR2 and I was wondering about gears to run, if i can stay with stock or if i should change, I still want good highwayabilty but at the same time i don't want to put the truck into a bind when i do decide to off road it, i'm also look at a locking rear end in the near future as well and am open for sugstions in that respect also
 
I would say go with 4.56 gears. Do you know what ratio is in it? I had a 97 nonzr2 s10 with 32's and it needed lower gears bad. If your zr2 has 4.10's you might be alright with the 33's. I found these codes might want to check inside your glove box if it tells.GU6 = 3.42
GT5 = 4.11
GT4 = 3.73
 
33's maybe but 35's will eat your front suspension and steering for breakfast unless you do a SAS. I had a non Z with 32's and 4.10's and it was pretty good. I think i would go 4.56 if you don't drive a lot of high speed (75+).
