Before ordering, have the following information ready: fine or coarse spline count on input and output shafts; upper torque rod style (single tapered ball stud hole or two-bolt dog-bone); whether your differential housing has four 3/4" bolt holes at the rear for a transverse rod mounting plate around the through-shaft; and your axle spline count. These details determine exact compatibility. Part number RBT-CRD92-4.17 or CRD92R417. Call us to confirm the right configuration for your truck before placing your order.
