Product review (4 stars): Works good.  These are a TWO stage shock, and there are TWO in the package.
As someone else posted, the first .5" of travel is not very dampened.  However, if you read about the new design, they say they are a 2 stage shock.  Yes, my washer shook a little more when coming up to speed, but once at speed, it was fine.  These fit perfect, and YES, there are TWO shocks and a spare push-pin.  To remove the pins, use a 1/2" deepwell socket to push the pin out to get it started.  On the other side, grab with pliers and pull.
