Not seeing many options for the 9.75, with a 4.10 gear. I prefer G2, but they don't make one, according to their website.
Is there a difference between the 2010 and 2012 9.75 rear end? I just noticed the year on it. I am thinking 35's someday, but don't think 4.56 is necessary, with a 5.0.

I don't really think 4.56 is necessary. My old 4.6 trucks it definitely was. I ran 4.56 and 33's, in my '05. Going by online calculators, my highway RPM would not have dropped much, going to 35's. I always felt they were too high.
Raptor was 4.10 and 35's factory. The coyote 5.0 isn't that much weaker, than a 6.2.
