I have 3:55 now and I want to get a performance diff like an eaton. What do you suggest for a diff and gears. I have an aode with a shift kit, soon a 3000 stall. In summer it my daily driver thats why I went with 3:55, but I read that a lot of people do 3:73 or 4:10 on their daily drivers with no probs. What do you think?
