Rebuilt International differentials
New, used and rebuilt International and I.H.C. truck differentials, front, rear and two-speed, with a full line of parts for International trucks.
We offer a full line of new, used and rebuilt International differentials. Our parts department carries parts for all differentials, and a full line of parts for International trucks.

International and I.H.C. models we rebuild
International Harvester (I.H.C.) built its own axles for many years, and those model numbers are still what you will find on older International trucks. The units we see most:
| Front differentials | S400S, RA351, RA355, RA472, RA474, N400, N400F |
|---|---|
| Rear differentials | RA351, RA355, RA472, RA474, N400, N400R |
| Two-speed differentials | G175T, M190T, M220T |
International is the truck brand of Navistar, so the same trucks and axles are often listed under either name. For Navistar units such as the RA-42 carrier, and for signs your differential needs attention, see rebuilt Navistar differentials.
