Product review (5 stars): Genuine Parts, fixed our problem
Genuine whirlpool replacement parts!  Our dryer stopped tumbling yesterday, did some research and opened her up.  The belt came right out, broken in half. I opted for this kit instead of just the belt. Took about an hour to install everything. Not only is our dryer working again, it's now sounds much more "smooth" when running. Saved myself about 100 bucks easy.  Our dryer is a whirlpool LGR7646JQ0.
