Product review (5 stars): We knew the belt was bad on our dryer
We knew the belt was bad on our dryer, but ordered the entire kit "just in case" we needed something else in the future.  Turns out the idler assembly was needed at the same time.  Instructions were thorough.  Repair was straight forward. Our vacation home is located in a remote area.  Having the entire kit saved us time and frustration and kept our nearly 40 year old Kenmore dryer working like a charm.
