Outstanding limited slip differential from an  E36 with 3.91 ratio.  This is 188mm sized differential. Very clean condition.   Turns smoothly and quietly. No debris in oil. This is the best there is! If  you are upgrading from an 'open' diff, this is an easy swap.  Comes with new cover gasket and output oil seals.  If you don't have one--this is a great upgrade for your car.  Every sports sedan should have a limited slip differential, and luckily, BMW makes them!

Overseas buyers are welcome! Please provide your city, state and postal code for a great shipping estimate, much lower than the eBay calculator.
