I had a 3 inch body lift on my k5 and 33s were no sweat..Im sure some all terrain 35s would work with some trimming. I do have to warn ya that the body lift does make the thing creak around a little and it wore out my body mounts....seems like I had to tighten the mounts up quite often....I will say that it does make dropping a transmission out very easy.....If I had it over to do I would have just done a suspension lift and not screwed my body mounts up. I did very heavy offroading with this truck though. I say if you plan on mostly street use, a body lift would be ok to get a quick lift and you could probably stuff some skinny(er) 35s under it. Just remember to tighten the mounts up once in a while because they can come loose.
