Rebuilt & Remanufactured Truck Differentials

Rebuilt and Remanufactured Differentials for Heavy Duty Trucks

We stock rebuilt and remanufactured front and rear differentials for Class 6, 7 and 8 trucks, plus new units for the most common Meritor models. Every carrier is listed by model and gear ratio, so you can match the tag on your housing and order the exact unit: Eaton DS404 and RS404, Meritor Rockwell RR20145 and RS23160, Mack CRD92 and CRD93, Dana Spicer, International RA472 and Fabco.

How to find your differential

Read the model and ratio from the metal tag on the carrier or axle housing (for example DS404, ratio 3.70). No tag? Count the ring and pinion teeth, or call 877-776-4600 with your VIN and we will identify it.

Rebuilt vs. remanufactured

Both are complete carriers torn down, inspected and reassembled with new bearings and seals and set to factory specifications. Every rebuilt and remanufactured differential comes with a 1 year, unlimited mileage warranty.

Core charge

Rebuilt units are sold exchange. A core charge applies and is refunded in whole or in part when your old carrier is returned and inspected, subject to the manufacturer's core policy unless stated otherwise in writing.
