I counted the ring gear and pinion and it is a 4.11 what makes me think its a JDM mechanical lsd is one of the sides where the axle goes in is deeper and has two wider sets of splines

Where did it come from? A lot cars came with LSD

 

[presterone]

An unknown source. What's the deal with one side of the input longer with two sets of splines?

My friend got it for cheapo from a guy who wasn't sure if it was a forester or something else.

svx rear diff was that way. one axle stub longer and different shaped. 

but that's 3.54 ratio

prob a rear diff from a forester with a lsd

Forester have non vlsd?

 

[SUBARUDE]

Nope I was wrong lol

Sucks I just can't pin point exactly what its from. I have had vlsd diff's apart but not a clutch type of torsen. I just dont get how this works and having no spare axle I can't really check the breakaway torque if it is an LSD.

Early Legacy turbos had 2 different length axles, but they also were VLSD.

I figured it out. The vlsd unit is on between the ring gear and the pumpkin which is different than the types ive seen so my axles should work. Another way to tell is if the shaft that connects the spider gears is flat its an LSD if its round its not.
