I have an 05 fx4 scab. I want to lift it (suspension) soon. So far it only has a leveling kit and I am running 33x18x13.5 MT Baja Claws and I want to keep that size tire. Here are the questions.

1) Should I go with 4" of 6" (keeping the 33s)?
2) What brand? Can you run it pretty hard? (just in case) (cost?)
3) Should I regear and to what? (cost?)
4) Anybody have have any pics that I can see?

Thanks
