I'd say good price because it's a rare bolt-in upgrade. If you have some fab skills and a welder, you can do an 8.8 with disc brakes cheaper.

Did you read the instructions? My aussie which is essentially the same as yours doesnt require special fluid, just the normal 75-90 gear oil. For heavy duty use and for towing they recommend 75-140 gear oil.
