Product review (5 stars): Wish I had done this a year ago.
Purchased this kit along with a Felt Seal that goes on the back of the dryer drum.

I've never worked on our dryer before, but it was not very difficult. There are plenty of videos on youtube that give you step by step instructions on the replacement. The belt was a little bit thinner that my existing belt, but my old belt was not bad, so I replaced it and kept the old one in my garage in case I need it down the road.  This kit comes with the triangular parts that keep the wheels from sliding off of the wheel shaft, with plenty to spare.  The repair was very straight forward, the product was just as you see pictured and it arrived promptly.

I would recommend going to YouTube and watching a video or two of the replacement before you get started. It will save you a ton of time if you have never done this type of repair before.

Our dryer started acting up a year ago and if I would have purchased this kit then, I could have saved myself some clothes that were damaged as a result of the drum having a large gap and the felt belt leaving brown marks on our light color clothes.

Very pleasant buyer experience.
