True Tracs use the same type of design as Torsen differentials, which were/are OEM on H1 and military Hummers. Helical limited slips are also prevalent in many Japanese high-performance and exotic sports cars. These types of units are "torque biasing", which means that ultimately if one wheel has absolutely no traction you still aren't going anywhere. For street use they are sweet and as you mentioned do not really wear out over time.
