Product review (5 stars): Different color than OEM, but should work fine
This worked for our KitchenAid KEMC308KSS04. Not sure why it's more of a shiny stainless color than the tarnished shade of the OEM (and the other new spring from a different vendor), but I don't think it should make a difference.

If you Google "technician Brian microwave torsion spring" you can find some good instructions on how to install them.

Hope that helps!
