Are there no 'upper control arms' with a truck arm suspension?

no sir, they are radius arms. but because of the triangulation and reduced deflection thru articulation the axle is bolted directly to them vs with bushings. also creates a little bit of a sway bar effect.

Interesting. I had never really looked into it much.
