Reccomendations for aftermarket limited slip diff

I have a 2002 Tundra V6 2WD and I want to put in a LSD. Has anyone done this and can anyone recommend a model? I know that LSD is an option on the Tundras. Does anyone know what type of unit is used for this option? Gear ratio, etc... Any info is appreciated.

I know that the Kazuma/TRD LSD included as an option from the factory is manufactured by Eaton corp. The exact same diff can be purchased without the TRD logos and such from different retailers who sell the same diff made by Eaton. I'm pretty sure you can find an LSD carrier for around $300, not sure how much install would cost.

Edit: Oops sorry. the Eaton diff is the same as the aftermarket TRD/Kazuma LSD. the Factory one is made by a different company (Dana?).
