Any automotive part that is produced using any amount of labor, raw materials, machining and engineering and/or intellectual property that is sourced from here in the US, we then would consider that item to be, at least in part made here in America, regardless where the final assembly or machining takes place.
Below is the 'grading system' used to rate the above brands.
Any brands marked with a gold star (100% value) shows that some (or maybe all) of their products are made in the USA using virtually all domestic sourced materials, labor & machine work.
A silver star (75% value) shows their products are assembled and/or machined in America using domestic labor and a mix (of any proportion) of both domestic and imported materials.
A bronze star (50% value) shows that their products are assembled in the U.S. using all imported parts.
An 'empty star' (25% value) indicates that the product is designed or engineered in the US, and/or some of the parts have been produced here, but are sent elsewhere to be assembled into a final product.
