Just throwing this out there because a lot of people fail to mention that clutch types do require some more upkeep than a torsen diff

Dug through the threads a bit, prices at least:

OEM Torsen - $3500 or so, online pricing
Toms LSD - $2000
OS Giken - $2500

OEM price is the entire diff unit i believe, i could be wrong. where as the other two you would need to open up the stock casing and put in the LSD

The LSD is not available separately, is it?

Here's a detailed thread I made a while back on the OS Giken Super Lock Traction Control Differential (TCD):
https://www.clublexus.com/forums/per...l-tcd-lsd.html

OS Giken LSDs require no more maintenance than a Torsen diff. Unlike other clutch-type diffs, there is no need for the OS Giken LSD to be rebuilt.

OS Giken recommends that you change the differential fluid every 30,000-50,000 miles (depending on use).

There's no incentive to buy the OEM spool by itself. The whole diff is only $300 more, and you will spend that just getting the spool into the housing if you get the OS Giken or Toms.

Gotcha, thanks.
