Getting ready for the big lift I just put a 9.75 rear in my 2004 Heritage XLT 4X4. Now I have been given a new set of ford racing 4.56's for an 8.8. I only plan on running 35's would the 8.8 handle these no problem? I do mostly highway with a small amount of off roading (only when the quads stuck). Should I just re-gear the 8.8 and just call it a day?
