New / NOS
Every Grade 5 part we stock in one place: new-old-stock and never-installed parts — original packaging, or unfitted take-offs with zero use. This is the largest slice of our inventory, and it's the reason our published 1–5 grading scale starts the way it does: Grade 5 means new, not "nice for a used part."
NOS Cup parts are the best value in this market — factory-new supply for older platforms is slow or discontinued, and a sealed 991-era assembly is the same part it was in 2016. Each listing carries the factory part number and platform fitment, so you can verify against your parts book before ordering.
