Product review (5 stars): Easy swap, improved design
This was a direct swap in for KitchenAid KUDI01FLSS2.  The cords were the same length as the originals and no noise from the pulleys at all.  I ordered from Amazon directly, not a 3rd party re-seller and the bag the parts came in indicated that these were genuine Whirlpool parts.

If your dish washer door is feeling heavy and/or falling down this is the solution.

The original design appeared to have created a lot of friction on the cords which likely caused the initial failure.  This new design has rolling pulleys on both the top and the bottom where the original was a pulley only on top and a plastic guide of sorts on the bottom.

Also, if there's too much or too little tension there are 3 positions for the lower screw that allow some adjustment.  Move the screw to the rearmost hole for the least tension and the front-most hole for the most tension.
