Wasn't just the rock, though. It was, literally, the bounce--the effect of high-traction wheels trying to turn. Same problem that caused someone to compare 4WD systems to Mexican jumping beans. Only, it was on a 6WD drop center. Lower traction at one end resulted in just the rock, and that's an issue that's easy to design around. The next two years, it was McMasters in the center and AndyMarks on the corners.
