Rear axle ratios
I've had a hard time finding a truck with everything I want on it, so I'm debating the need for higher rear axle ratios. Here are the net 1st gear ratios for various half-ton trucks: Make Rear ...

What are the tire diameters. As that can make a difference too. A 2" diam change is like going from a 3.73 to a 4.10 if you go smaller, or a 4.10 to a 3.73 if you go to a larger tire.
I'm just considering stock tire diameters. If I were to change up to large off road tires then I think a gear change would be important.

Also torque plays a part in the take off part too.
Exactly. So as a rule I'd expect turbo-charged engines not to need to much gearing because of their low-end torque. For some reason though the 5.7 Hemi felt faster off the line than the Ecodiesel even with the same transmission/rear end ratio and with less torque down low.
