8121770421DOD is a Meritor interaxle shaft. On a tandem drive set, power is shared between the two axles through an inter-axle differential, and a shaft carries drive onward from the forward axle to the rear one, so this shaft sits in the middle of the tandem driveline. A genuine Meritor part from Pro Gear and Transmission. Meritor tandem axles come in several builds, so call us to confirm proper fit for your application before you order.
