Ingals arm are made out of small diameter mild steel tubing. Ingal arm been known to snap, too small hardwares, not enough "meat" to take the load.
These tie rod are teflon lined, have 3/4 shank, same as the balljoint end too. Heavy duty thick as ASS steel tube end (high and above the wall thickness of those swaged end on AFCO tube - thanks Larry for pointing that out, I forget to talk about that on my initial post), chromoly tubing, lap and rosette double welded connection.
Al Pacino would look at this and say HOO HAAA!!
