A little truckin' history for you people, here from the left coast. At one time, the general school of thought was that Budd hubs were for highway trucks, but if you wanted to work your riggin' in rough country or on heavy hauls, the Dayton was the way to go. So, if I had a 3408-powered tractor and I wanted to pull it off the road and put it to hauling logs or wotever in the bush, I'd have thought hard about those adapters, for the drive axles at least. I know this: Once you've retorqued a Dayton 'till it won't retorque no more, you can put whatever power you like to it, and it won't spin.
