Since then, Positraction (often shortened to "positrac" or merely "posi") has become a genericized trademark for LSDs.
Other factory names for LSDs include:
Alfa Romeo: Q2
American Motors: Twin-Grip
Buick: Positive Traction
Chevrolet/GMC trucks (after 1973): Gov-Lock
Ferrari: E-Diff
Fiat: Viscodrive
Ford: Equa-Lock and Traction-Lok
International: Trak-Lok or Powr-Lok
Jeep: Trac-Lok (clutch-type mechanical), Tru-Lok (gear-type mechanical), and Vari-Lok (gerotor pump)
Mopar: Sure Grip
Oldsmobile: Anti-Spin
Pontiac: Safe-T-Track
Porsche: PSD (electro-hydraulic mechanical)
Saab: Saab XWD eLSD
Studebaker-Packard Corporation: Twin Traction
TVR: Hydratrak
