Over the years I have really come to despise stamped steel pulleys when trying to drive serious current. Whenever I can source a billet machined pulley I do. These pulleys seem to work best under high loads.


The belt pictured here is also one of my favorites, it is a Dayco Top Cog. When I can't source a Dayco Top Cog I usually use a Gates XL. These Gates belts are sold nation wide by NAPA as the NAPA Premium XL Belt.
