Product review (5 stars): Definitely notice a difference after install (no squeak with new units like there used to be)
just as advertised. I bought to replace one side that busted.  I received two as advertised and replaced both sides.  It took about 30min to slide out the dishwasher, pop off the old pieces and install the new.  cords were exactly the same as original.  This was the new model that has pulleys on both ends (my old that i replaced had a stationary end and a pulley end).  Definitely notice a difference after install (no squeak with new units like there used to be).  I have a Kitchen Aid model KUDI02IRBL3
