FElony, your not thinking this through. The parent no longer makes/is interested in camshafts. They sell the rights for a defunct product line to another firm, likely with a non-compete clause on all the other 'stuff' they make an sell. No competition, no muss, no fuss and both parties get something...money in one case, trademark/advertising right in the other. Easy-peasy!
Who actually manufactures the cores, does the grinding, heat-treating, finishing, etc...who knows!
I think
Offshore crap, one companies name, another's companies grinds.
But then, why use a name still owned by a big company that can sue you, when the name is mostly forgotten and doesn't really offer a marketing advantage? Why does the GK website have an empty category for Automotive Aftermarket?
