I would say 4.56's are going to be a happy medium for 33's or possibly 35's.

I've been running 35's on a 30 and 35 for years.
You dont have to get axles, but with the tires a set of Chromoly front shaft's would be a good upgrade.

Your going to need a 373 and up carrier for the front unless your putting in a locker at the same time.

If you put an ARB or a Detroit locker in the rear you can get a 30 spline axle kit, which is a huge upgrade in strength.
