Product review (5 stars): Stronger - With Reinforced Metal.
It absolutely amazes me how much more inexpensive these are on amazon compared to other places, but that's a side note.  The real beauty is removing the old ones and putting these in and feeling the glory of a job well done.  It took a little time to remove the motor on the washing machine just because of the confined space it's in, but after a little elbow grease I was finally able to swap these out.  These are much stronger than the stock/OEM versions because of the metal reinforcement in the center.  I guess, they took notice and fixed the flaw.
