This kind of UCA is utilizing a heim joint in the lateral position set up in a double shear configuration. Super strong and the heim joint being in that orientation removes the heim as a limiter of travel. However, with the joint in that rotation your steering angle suffers, so does the steering performance. So it’s not really good for anything but a fast desert prerunner. Also it requires a completely custom spindle (the heim joint actually sits in the spindle) so basically you only see this configuration in one-off front ends.
That makes sense. Thank you for the complete response!
