I planning on building a tj on tons. I am looking at using super-duty axles. Meaning a Dana 60 and Sterling 10.25. I want to be able to run 40s or 42s but don't know how much lift I will need to acomadate the size and still flex. I am planning on building it on coils till I can afford a set of ORIs or Coilovers What lift kit or size would yall suggest for it?
