      Original Mopar fluid and don’t forget the additive that goes in there too.

      I did some research on this as well. Just use the Dodge factory stuff. Oh and, like Speedtactics said, do not forget the limited slip additive for the rear!

      I have a Gen III Viper upgraded to a Gen IV hydrolock differrential. Do I use the same oil in the Gen IV differential as I would in the Gen III? Also, what is the best fluid to use on it and the transmission. Thanks!

      Just for clarification purposes, the Hydrolock was an 03-06 item. Gen 4 Cars 08-10 used Viscolok.
