I've never even heard of one in a 1-ton. All the two-speed rears I've seen were in 1-1/2 ton and larger trucks.

I'd ask the guy how many lugs they have. If they have 8-lugs he may know what he is talking about, if they have 10-lugs they are for a larger truck.

It's true. I really don't do anything but browse the Internet looking for trouble...
