You get what you pay for in auto parts as in most things in life.
NAPA had to compete with national discount auto parts stores by selling cheap import parts because the public wants cheap parts (the Wal-Mart affect).
I and most people on the board would prefer a quality part. Just being made in the US is no longer a guarantee that it is a quality part any more, but most of the older American brands that still have plants here do make quality parts (like Moog, and Timken) provided you ask for the American made part by name. Otherwise it will be a Timken bearing that is made in Malaysia that you get, or the suspension part from India, or the brake part from China that delaminates the first panic stop you try to make.
If you don't ask for the higher priced American part the counter man will not offer it. NAPA has two complete different lines of parts Inferior but cheap, and OEM quality parts that are much more expensive. Shelf space is devoted to the part that makes the store money (but thankfully most towns have a NAPA warehouse with the good part in stock and can have it at your neighborhood store the next morning (the national discount chain has a warehouse also but all it has in stock are discount aka cheaply made parts). I notice that Wal-Mart and discount auto parts stores are spreading like mushrooms, so train your kids and neighbors to ask for the good stuff.
