Product review (2 stars): Lasted about 18 monsth
UPDATE: 6/60/2015  The part did work well for about 18 months but failed in the same manner as the original. It broke along the median line.
Although the modifications I mentioned below did make it last longer, it did fail in the same way. I have come to the conclusion the part is poorly designed and at freezing temps it becomes brittle and subject to premature failure. I have noticed one issue with the formation of the ice cubes. If the box is not leveled correctly the small notch that allows water to spill from one slot to the next allowing the filling of the gang of ice cubes get rather thick. As such, the cubes are hard to break apart and puts even more stress on this bearing. I am not sure how to fix this problem. Maybe there is a timing control which regulates the fill time? I think more research is in order.

Received on time and in good condition. It was easy to install and works better than the original part. Easy to install.
The GE Arctica has a problem with the ice maker bucket. The screw which moves the ice forward will catch on a block of cubes and lift it out of it's track breakings this part. I found that if I placed a small binder clip on each side and flipped the small wire ends up, it would keep the ice bucket from being lifted out of it's track and less stress is placed on this part. Works well for me. I did have concerns about the clip ends being forced through the plastic shell but so for so good. I am sure it would void your warranty to use the clips in this manner.  I would purchase again.
