The Stovebolt Site Forums The Shop Area The HiPo Shop Comments on powertrain for 38 chev truck

I am not sure what the differential ratio is right now. All I can say at this time is that it is still the original closed tube drive line for a 1938 Chev 1/2 ton truck, I have not removed the differential cover yet to check the gear ratio, but may need to confirm that at some point.

I just checked the "GM Heritage Center" web site and it lists the differential ratio as 4.11 to 1 for a stock chev 1/2 ton closed torque tube drive line.
