Product review (5 stars): Dryer belt, idler, and roller kit was very convenient
These parts for my Kenmore clothes dryer fit perfectly, and buying the entire kit is an economical move long term.  I only needed a new drum belt, but I also used the idler pulley included with the kit.  I may eventually also use the rollers in the kit.  I suggest buyers carefully track down the individual part numbers needed for a dryer repair , before ordering any parts or kits.  For my 15 year old dryer, a Sears site showed the part numbers needed, and Amazon.com sold the kit at a good price.
