Hi mates i recently purchase this LSD used for my S21 Tranny and the seller told me that it came from a ITR tranny but when i turn al low speed it locks very hard so i want to know what kind of LSD i get before installing it i disassembly it and it came with 2 disk inside and i think that OEM LSD dint came with disk help me please this

 

Could easily be a Kaaz LSD. Check serial numbers, etc. YOU CANNOT USE OEM MTL FLUID OR SYNCHROMESH. You must use KAAZ oil or Motul PA-90 Fluid with a Friction Additive.

 

Thank u man but i dont see any serial number on it could you tell me where i can find it

 

It's been a while since I've only gotten new ones which came with a s/n card. Check at the bottom of the bell housing.

 

Tomorrow im putting some new pics

 

 

Looks like an older Kaaz to me.. either way, its a mechanical differential.
