I just installed a set of 385/70R16 (38x15) on to my truck ('02 F250 v10) and I have a little rubbing issue on the rear of the front inner fender. I have a 6" Skyjacker lift in it and an extra leaf in the rear. When I go more then a full rotation and a quarter on the steering wheel it rubs against it. Its rubbing just at the bottom part. My leaf springs and front bumper are clear as I shimmed the front bumper out about 1 1/4" already.

I was wondering what are my options for getting that little bit of extra clearance. I dont go off-roading at all so Im not going to be using the full range of the suspension.
I know I could go another 2" up but I'd rather keep it the same height as I still want to be able to use my trucks box. But if thats the only solution, I guess another 2" is it.

Any help is greatly appreciated.
