I don't believe they make 3.90's for the 7.5. Just got with 4.10's, if you want more, or 3.73's if you don't.

My 3.73's work great man, I bet you won't be disappointed, I know i was actually more impressed than I thought I would be.

You can use different diameter rear tires to adjust your final effective gear ratio. Here's a post I made about it:

In my case, I have 4.10's and 28" diameter tires, which gives me a final ratio of 3.95:1
