Product review (5 stars): Kitchenaid replacement top rack adjuster
It is not an OEM part but it fits and works fine. It does not come with any instructions and I wish it did. It took me some time to look online and finally found an youtube video to get an idea how to install it. It did not take long to take the old one out and put the new one on once I figured out the process. I have it for a month or so and hard to comment on quality at this time.
