The 2 ton and larger two speeds generally have a regular gear and a slower one, they were intended to get a load moving, not go fast.
I have heard of a few old two speed small rears, but not actually seen one in person. I think Truckstell is the brand, but check the spelling.

Sounds more like something IHC or Diamond T would have done. | | |

It was in a '41 3/4 ton. That was about 16 years ago last time I saw it. Unfortunatly, the owner had an auction and sold almost all of the collection (mostly parts cars) exept for 1 '41 1 1/2 ton stake and a '55-'57 school bus. I beleive that those have since been sold as well.

It is basically the same thing except it bolts on to the end of your stock tranny instead of in back near the pumkin. It's been a couple of years and I'm still working 2 jobs to pay for it  | | |
