Hammer, I just got back from test running the truck for a trail ride this weekend and see that you got the problem fixed. Yes I have seen your post on the rockwells.If you need anything , let me know. I'm running 48" Michelins with a spring over ( NO BLOCKS ) . The way I fabbed up my spring hangers I gained another 4" . This was the LOWEST that I could keep the truck and still have any kind of tire clearance. I would like to have put a little more backspacing in my wheels , but that was as much as I could put in them and NOT get any tire to spring rub ( on the rear steer I have the springs moved in under the frame). My point is that if you are going to run the 53" tires you are going to have to be several inchs taller and possibly have a wider stance then I'm running. Barry
