Hi i am thinking about ordering a new Denali dually with either a bigfoot camper or northern -lite Question is it better to get a I think a 7.30 or a 4.10 gears for the truck rear end, what is t...
3.73 in my 6.2 Gas F350 with 5,000 lbs in the bed does just fine. I think I could hold 6th better with 4.30's, but that's the only advantage I could see. With 6 gears it's pretty irrelevant.
I do drive the truck a lot lightly loaded without the TC on, and for that I definitely appreciate the 3.73's.
Ford doesn't offer 4.10's, but that would probably be the ideal gear ratio in my situation.
