At some point, we get to the weakest link. Since the tie rod's tapered stud still has to fit into the steering arms and centerlink, at what point does that become the failure point? Did the NASCAR boys run stock centerlinks and steering arms? Or where they upgraded to fit the possibly larger tapered stud on the HD parts?

I dunno

They say there are no such thing as a stupid question.
They say there is always the exception that proves the rule.
Don't be the exception.
