It is not nearly that much.
Assuming this F350 is a SRW model, you have a Ford Sterling 10.5" rear diff. Fluid capacity is 3.3L. You will need to buy 4 quarts and will have a bit left over.
As Brian said, it is limited slip. So make sure the oil has friction modifier built in. I'm pretty sure RP does, but check the bottle. Mobil 1 is also a good choice. Synthetic is required.
