4X4 To quote from the ID plate, "Truck, 1/4 ton 4X4, M38". This was the Jeep supplied by Willys that had a 3 speed manual transmission plus a 2 speed transfer case, giving it a total of 6 forward gears. Also, there was the one that was officially labeled, "Truck, 2 1/2 ton 6X6, M34". This one had a 5 speed transmission and a 2 speed transfer. These were mostly supplied by IHC and Reo. There was also the M134 with an identical specification that had a 2 speed transfer and a 4 speed automatic.
The nXy designations translated to N wheels on the ground, Y wheels driven. Dual wheels counted as 1 so that the 3 axle 10 wheel truck and 3 axle 6 wheel truck were both counted as being a 6X6. The tonnage rating on the ID plate was the offroad rating, so the 2 1/2 ton had a secondary rating of 5 tons when driven on a paced road.
Something I've wondered about (for at least 8 seconds), if you bought one of the HD clone "factory choppers" and chopped it, would you have a chop-chop?
