Rear End ratio help

[CarlC]

With the kind of daily mileage you are doing, I'd consider something numerically lower than a 3.73:1.

You can easily support a 3:30-3:40:1 gear if you have 400 lb-ft at 1750. You will likely have to downshift for any spirited passing.



At least with the 9" you have a lot of options. 12-bolts are more limiting. I'd throw a 3:42 in mine in a heartbeat if they were readily available.
