Hey My70Chally, what are you running now? I've been this route here a few times asking questions about possibly changing mine to a 60 and come to the conclusion that the biggest bang for the buck is the 8.75 by far. The diff is very easy to swap out if needed, they are plentiful, they are tough, they are well, you get the point. :thumbs: I have a friend (really) and he has been racing for over 30 years and running the 8.75 the whole time. He actually laughed when I asked him if they are pretty tough. He claims that where the meat really counts the 8.75 is tougher than the fard 9" and it has the drop out diff as well. Just some stinky opinion is all. :thumbs:
