Our innovative "Two-Cut" manufacturing process ensures the lowest tolerances possible for the quiet operation required by our OEM customers. This "Two-Cut" design also allows for easier set up in the aftermarket replacement business. The combination of materials, heat treating and cut geometry allows for a gear set that has ten-times the life of a non-OE gear set.
