The Mack CRD92 front drive differential with a 5.55 gear ratio is sold here as part number RBT-CRD92-5.55, also referenced as CRD92R555. Before ordering, have the following on hand: whether your input and output shafts are fine or coarse spline, whether your upper torque rod mount is a single tapered ball stud hole or two-bolt dog bone style, whether your differential housing has four 3/4" bolt holes in the rear face for a transverse rod mounting plate around the rear through-shaft, and your axle spline count. These details vary across CRD92 applications, and confirming them upfront prevents a wrong-part return. Call Pro Gear and Transmission to confirm proper fit for your truck before placing your order.
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.
