The Meritor MS1914X3DFRNN517-513 (also referenced as MS1914X3DFRNN517513) is a genuine OEM drive axle assembly. Meritor engineering backs this as an original drivetrain component, carrying the same part designation used in Meritor's own product catalog. The "MS" prefix identifies this as a Meritor single-reduction drive axle; the full part number string encodes axle configuration, ratio, and option codes specific to this build. Because drive axle assemblies are highly application-specific, Pro Gear and Transmission recommends verifying the complete part number against your vehicle's axle tag before ordering.
