Ok...I understand the need and the geometry of a 4 link rear suspension. But ...after viewing many threads on this style of suspension connections, some fabricators use a very custom design in their "bars" in the shape of the overall system, some with parallel bars, others with links going in many directions. Believe me, I have looked at hundreds of posts. I just can't get my head around the reason for the different designs, if for no other reason than to be different. Do some designs handle loads better, some handle lowered rides better, etc??? I admit I am ignorant! Don't slam me to hard!
