[Edit. oops wrong section.] Mods feel free to move to OEM tech.

Was just wondering if anyone know the rpo code for an lsd 8.25

I don't think mine has the option. If not i know how to check it.
figured i'd save myself the time of jacking her up.

When i changed the rear diff oil i never added the modifier. i don't what i was thinking i just forgot to even see if i needed it.

I'm not haveing any issues and its been almost a year since i did it.
thanks.
