Product review (4 stars): great genuine part replacement for me and it arrived on ...
Fits perfectly in my GE oven.  Do your research and make sure you're ordering the right part for your oven.  My only complaint is that I thought this was for 2 racks based on one of the questions/answers below, yet I only received 1 rack.  I feel that $31 is a bit steep for 1 rack so I deducted 1 star.  Otherwise, great genuine part replacement for me and it arrived on time.
