I don't know how much of my 2017 Ram was made in Mexico but the springs were for sure. Rebuilt one Cummins and the connecting rods were made in Brazil and so marked.
Theoretically, if mexicans have good jobs and living conditions, they won't be tempted to move to north. Trouble is, they, like so many others, refuse to accept birth control as being of any value and their country is over populated too. GD
