The Mack CRD92 front differential with a 4.42 ratio is sold by Pro Gear and Transmission under part number RBT-CRD92-4.42, also referenced as CRD92R442. Because CRD92 differentials vary in input and output shaft spline type (fine or coarse), upper torque rod configuration (single tapered ball stud or two-bolt dog-bone style), rear housing bolt pattern for transverse rod mounting, and axle spline count, buyers must confirm these details before ordering. Call us with your axle specs so we can match this unit to your exact application. This differential is sold on an exchange basis, and a core charge applies at the time of purchase.
