Poor Little Cone Style

It does not matter. It is a spring preloaded cone type limited slip unit. The only difference between it and a factory unit is pretty much the preload spring pack. Their design is the same. Where do the "side gear separational forces" come from? From torque being applied. It works just like I described. The preload spring pack holds it all together so that the torque from the drive shaft CAN ramp the cones up against the case. It does not matter whether it is aftermarket or factory. The design is identical.
