No springs in a Kaaz LSD, just ramps.
Without torque on the other axle it won't lock up, sorta like a Quaife.
My Kaaz lasted 50k miles on the street, autox, and drag racing when I finally broke both drive plates on one side.
I don't have any pics of when I tore it apart, but might be rebuilding it over the winter to sell to a ITB/ITC Honda Racer.
