Product review (5 stars): Works great!  Love the upgrade piece.
I've had to fix my dryer a few times and this kit so far has been the best one.  The plastic tension roller was an upgrade to the metal tension piece that was originally on my dryer.  If this says it is the right kit for you but you have a metal tensioner that the belt slides along get this kit!  The wheel works much better and makes assembly a lot easier.  I did not use all the pieces either since I believe this kit is probably for more than one type of dryer.
