Can anyone confirm specifically what type of "anti-spin" limited slip differential is used in the Cummins 2500s? I know AAM produces both a clutch type and a Torsen gear type TracRite differential, but I wasn't able to find anything specific on this forum, and other places claim RAM uses the gear type for all equipped HD's, except the Power Wagon which has the electronic locking, gear driven LSD in the rear. My owners manual says to add friction modifiers when changing the diff fluid (for clutch-type LSD's), but it's also been said that is incorrect and wouldn't apply to the gear-type.
