Product review (5 stars): Fit perfectly; not OEM.
It fixed the issue with my agitator - the old dogs were completely worn out. The other parts may have been unnecessary, but the existing ones were fairly worn, so replaced them as well. The style wasn't exactly identical to the existing (mix and match part of this kit with some old parts wouldn't work), but the important dimensions were correct and everything fit into place without issue.

It isn't an OEM part, but not sure what the benefits of that would be, given the fit is the same... Easy fix to an old unit for a good price.
