Product review (5 stars): Perfect fit for Kenmore Series 80 dryer.
Others have mentioned the angle of the pulley/tensioner and how it may interfere w/ the drum.  I have a Kenmore series 80 dryer, with the non-wheeled pulley/tensioner and was concerned when I installed it, but no worries, everything worked fine.  Along with the belt, pulley/tensioner and wheels, I got new nylon lock 'triangles'.  Everything worked great, and the job was done in under an hour.  I found over a dollar in change, and 4 guitar picks as well, and about 10 years worth of lint.  Dryer runs like new.
