Well the 3inch body lift is out and new daystar 1inch installed. Think 31" tires will be fine. The bolts were a b**** to get out of the six center mounts. They were frozen to the steel sleeve inserts. I had to cut bolt under body puck then cut the head off with torch to get them out. Had one that nutsert was messed up so removed it replaced with body washer, lock washer and nut. 18hrs later glad that job is done.
