I just need to know if I run 6" lift will 37x12.50's fit w/o rubbing? I would rather not cut my truck. Would it be better to got 4" and 35's? I will not be doing much wheeling, just some mud every now and then. I have a d60 and 14bsf, 4.10's and no lockers. What other mods will I have to do for 6" lift, is making the driveshafts longer neccesary?
