KYB SSS Aftermarket Rebound Mid Valve assembly? Who made this?

Anybody know who made this setup? Came off a 2009 YZ450F, the compression shim stack is pretty stiff looking and then this thing shocked me. I've never seen it before.

I'm still curious as to the manufacture and what type of riding this valve was designed for. 

Below is the compression valving, note the LSV is bypassed and this is by far the thickest compression shim stack I've seen.
