Product review (5 stars): Took the "thump" out
This is the 4392065 kit with a "free" 3392519 fuse taped to the outside of the bag. Kit has the 2 rollers with 4 retaining clips & a push nut for the roller support bracket. A belt made by "FSP" which was the company that made my original belt. Also contains a complete idler pulley assy. I did notice that the outside surface of the new idler was "convex," and my old one was flat. They interchanged perfectly & the new design may have some sort of an advantage, but I'm not sure what it may be. My old fuse was not blown, so there wasn't any reason to install the new one at this time. I left it in the bag it came in & taped it to the back of the dryer for future use.
