This 4.78 ratio gear set is built for Navistar differential applications and is built as an aftermarket replacement. It meshes the ring and pinion teeth to convert speed and torque within the differential, matching the original ratio for proper power transfer to the axle. It is sold individually for heavy-duty trucks requiring this ratio.
