I just got home from the moab easter safari, and i met this guy running a rear A frame suspension on upper helldorado. I had never seen it before, He had an A frame welded solid the the axle, a cross member with a huge "ball joint" that he took off a road grader mounted in the center of the cross member. Then a panhard bar and some limiting straps with coils. It was very simple more so than a four link and I later heard that some use it on drag racers. I wanted to know if anyone is running this on their cruiser, because I want to on the rear of mine. I would like to see some photos.
