Product review (5 stars): For 3/8" heating element applications
This kit contains Heating Element WE00X422, which I understand is no longer sold separately.  So even if you don't think you will need the insulators that come with WE11X10007 because your original insulators are intact, you will still need to order this kit to get the 3/8" diameter heating element if that's what's needed in your dryer.  The 3/8" element is properly sized to fit through the ceramic insulators that are about 7/16" inside diameter.  Do not buy WE11X203 thinking that will do the job because all you need is the element and not the insulators - WE11X203 is the 1/2" diameter heating element which will not thread through the 7/16" ceramic insulators. I didn't need to use any of the included insulators in this kit but with the heating element I fixed my dryer and am happy with the purchase.
