here's a couple more.
This is not right...The upper bars and lower bars should be the same length, always at the same angle, and pivot from the same point.
for adjustable suspension, yes.
But a lot of 4 links are bought from other kits, like TCI's 34 Ford rear setup for coil overs. When you talk about less than 5 inches of travel (thats 2.5 inches either direction) the arc of operation wont change the pinion angle. The shorter upper bars are to keep the passenger compartment from being infiltrated with bars.
But yes, for our trucks the closer to equal length the better. My uppers are actually 3 inches longer than my lowers because I aam ising a mechanical advantage setup for about 12-13 inches of rear lift and my pinion does not change.
