      Sprocket

      This is a very sturdy sprocket that worked well for my DIY project. It is the only place I could find my specific dimensions.

      Great Sprockets!

      These sprockets are very good and they last just like the name brands for a lot less money!!!

      Help

      Would this replace the stock sprocket on a 1 inch shaft clutch?
