my front axle is 3.07s I can only assume the rear is the same or 3.08s. The truck has 31s on it now I am wondering what kind of pulling power and bottom end the PO had with this setup, I will be putting 35s on. its not an issue to do the gears for me, Im thinking 3.73s or 4.10s with the TH400. What do you guys think?
