CNC billet aluminum construction Teeth are gear-cut to RMA standards for a perfect belt fit Reducer is included for early model applications (1.9" center hole) Made in the U.S.A. .
The product its self was ok, but shipped in a thin cardboard box with thin foam around pulley and both sides of the grove guides were damaged from shipping. Pulley very heavy and should have been packaged way better for how heavy and how much the pulley cost.
