Product review (5 stars): We replaced them with this kit and it was easy to do
The top rack adjuster on our dishwasher was plastic and parts broke twice in a year of buying it. We replaced them with this kit and it was easy to do. No breakage so far. You can tell right away that the parts are superior to the factory installed ones as soon as you pull the top rack out and push it back in. This is what should be in there when you first buy the very expensive dishwasher we have.
