Engine & Internal - twin trac lsd?

http://www.azracemachine.com/products/TwinTracs/TwinTracMenu.htmhow does this work? does it just lock both wheels at all times or would it actually work like a helical lsd where it sends the drive to the tire with the most friction..

this looks a ton easier to install than the helical obx one, and if it locks both wheels that would be good nuff for me ;)


and OOPS wrong forum section sorry guys

regardless of easyness, you still need to split the trans case to install it. its a cheap alternative to a real lsd, and therefore it will never be as good as a real lsd like a quaife one or a factory honda one etc.
