These Chevy setups are not 2 links. The way they are built allow for flex, they are not dom tubing, not are they parallel to the frame. They also are on a truck that may see 7 inches of suspension travel through it's whole life. Maybe 4 if driven on the roads daily. Maybe.
Also, i've heard the whole nascar argument using 2 links and trac-bars. Those are the same deal, a nascar MIGHT travel a half inch at any time.
These two setups both don't have enough travel really mess with pinion angle, and if it does change, it's not in the same way our trucks hold position at bad angles.
