Rear gear change

[JOZW30]

Thanks guys,

I found a calculator for RPM with a specific gear ratio and tire size. With my BFG's at 65MPH with the 3.73's, I'll be running around 3100RPM. Again, it's usually less than a couple hours total between 3 or 4 trips.

I don't think I have the space for a second rear to hang around just for highway trips but the idea makes sense.

I sense from the responses so far that having this done proffesionally is the best route.

Thanks again for the input.

Joe
