Description:Cat® Differential Shafts are metal bars that join parts of a machine together, enabling power and movement to be passed from one part to another and designed to drive a pair of wheels while allowing them to rotate at different speeds. Cat designs and manufactures its differential components with these demands in mind. The result is a differential that lasts longer and works harder over the life of the machine.Application:Consult your owner’s manual or contact your local Cat Dealer for more information.
