Ok so unfortunately the Dana 60 rear end is no longer available. But he does still have the other axle with the 4.57 gear in it. He says it is a full time axle... should I be concerned about excessive wear?

I'm currently running BFG 35s on my truck and I would like to stay with a 35in tire. What do you guys think about 4.10s with 35s? I don't really do any highway driving, mostly just around town and a little off road as well. I also haul a 6x10 cargo trailer occasionally. The more I think about it maybe I should just keep my 4.57 gear. I'm happy to cruise at 55 and my truck turns about 2700rpm (although I think my tach reads about 200 rpm high). The truck has a 307 and the sm465 trans

Thanks again for all the info guys I'm learning a lot here
