Differential Code

[DarKane]

Ok so i managed to find the metal plate that specifies the ratio on my differential and the code sounds like this : 1140A4060S ... no coma,no nothing...wtf is this?? i am 100% it's a LSD because i exploded 1 set of tires doing burnouts in the neighborhood.can anyone tell me the ratio on my differential please?
i attach a pic with the metal plate

Thanks :up:

it looks like 11:4 or 2.75?

3.63:1 , The big S at the end is the LSD id. The A signifies a replacement Diff.
