89K5
1/2 ton status
35's fit w/4 inch lift. But if you want to do any four wheelin' (you have a K5, I hope you do)you HAVE to cut the fenders. I can't got over anything bigger than a curb without fear of crushing the fender. See the Tech article. Its a future plan for me, unless a two inch body lift doesn't strain the driveline too much.
