Product review (5 stars): Factory original parts that installed easily...
Dryer was very noisy and I ordered this kit. Only one idler was principally at fault (was lopsided, lol). Anyway I went ahead and installed the whole kit. There are online videos which are very helpful with the install. The kit contains factory original parts which fit properly without needing modification. I didn't work very quickly, but I believe I finished in less than an hour. All in all, this is one of the more satisfying repair jobs I have done as of late.
