I looked at my 85 Crew Cab dually tag the other day trying to order ball joints....and mine says its a 3850 front end rating. I've been trying to research as much as possible on this truck as I'm about to replace the control arms(one is broken and too rusty to fix). I have control arms off a 92 D350 dually diesel truck, so I hope they interchange and I ordered ball joints for a 4000# front end. I hope the right parts are coming.

You should be fine. I believe its 3800-4000. All diesels are 1 tons. Control arms should swap without any trouble.
