The Mack CRD93 rear-rear differential with a 4.42 ratio is sold under part number RBT-CRD93-4.42 or CRD93R442. Before placing your order, have the following information ready: whether your pinion has fine or coarse splines, whether your upper torque rod mount uses one tapered hole or two bolt holes, whether four 3/4 bolts protrude from the rear of the differential housing for a transverse rod mount, and the spline count on your axle shaft (count the teeth directly). These details determine exact fitment and affect which configuration ships. This unit is sold on a core exchange basis. Call Pro Gear and Transmission to confirm the correct configuration for your application.
A refundable core charge of $1,500.00 applies to this item and will be collected at checkout. The core charge is refunded upon receipt of your returned core, subject to its condition; customer is responsible for return shipping. Call us at (877) 776-4600 for details.
