you can get articulation out of a 2 link just use your head and some of these sweet joints that people make these days, i just experimented on a truck that was already 2 linked. i put the spherical bearings on each end of the link bar, solid mount at the axle and a diagonal track bar with heim joints and high offset washers and i dont know how but it pivots like a mofo doesnt make sense to me but it worked.
thats not possible. the pivot of a two link is locked by the bars solid connection to the axle, not by the bushings used at the front. if you drew a line through the center of the bushing and tried to twist the bar, the angle of the line normal to the frame, even with a half inch of twist, would mean that the the bushing on the opposite side would need to move down a FOOT to articulate that half inch on the first side. Super pivots on a two link are useless, because both forward bushings behave exactly the same.
Most likely you are flexing the frame, or the saddles or both.
People get confused when they compare a two link to the trailing arm system used on semi trucks, or the system used by nascar. Semi trucks use I beams, not rigid tube, that allow flex. Nascar autos have very limited travel and therefore almost no pinion change. Using box tube for a two link on a truck with air or hydro adjusted suspension isnt really directly comparable to anything currently used in rear suspension design. I dont think its unsafe, lots of guys rock monoleaf which is potentially more unsafe than a thick walled two link. I just think its kind of a cop out, you will spend thousands on your wheels and thousands on your paint and hours and hours in body mods but you use the cheapest, simplest, and worst rear suspension design. Its like a supermodel with bad teeth.
