    Since you are bragging about much smarter you are than everyone else, why don't you tell us how it works.

    Yeah, but it is hard to find on a < 802a truck that isn’t customer ordered.

    Heresy! Blasphemy! You want us to roll into Starbucks in a Lariat or worse, an XLT?

    I wish they made a 2WD Raptor........

    I don't understand the science behind it, but I guess I would rather have it and potentially not need it rather than need it and not have it. So, I am glad my 802A came with it.

    You know if you don't get it, there will inevitably be that one time you need it...

    :ROFLJest::ROFLJest::ROFLJest:

    The Torsen differential works just like a conventional differential, but can lock up if a torque imbalance occurs, the maximum ratio of torque imbalance being defined by the Torque Bias Ratio (TBR). When a Torsen has a 3:1 TBR, that means that one side of the differential can handle up to 75% while the other side would have to only handle 25% of applied torque. During acceleration under asymmetric traction conditions, so long as the higher traction side can handle the higher percentage of applied torque, no relative wheelspin will occur. When the traction difference exceeds the TBR, the slower output side of the differential receives the tractive torque of the faster wheel multiplied by the TBR; any extra torque remaining from applied torque contributes to the angular acceleration of the faster output side of the differential.

    For those that need the instructor led class. See below.:mwah1:

    And at least according to some people in this forum the Torsen is the source of the crazy levels of torque steer the Raptor has in 4wd. It would be interesting to hear if the non-Torsen models have as much of steering feedback in 4wd.

    As a factory option the Torsen is $500. To add it after the fact will easily cost 3-4 times that amount. Better to have it and not need it than need it and not have it.
