Just for your info, yes the eaton truetrac heads are like a factory replacement. Just install and set up like usual. AFAIK they are like that in the hilux, ford 9" and mopar options.
WAY better than any of the factory lsd types. Just be careful to run the correct fluid, do not use any of the lsd oils, and think even the synthetic options are a no go, just run basic 80-90 or 90-140 mineral gear oils.
