Rebuilt Eaton differentials
Exchange and rebuilt Eaton differentials for heavy duty trucks, and every part your shop needs to rebuild one.
We keep a large inventory of ready to ship exchange Eaton differentials, and we also rebuild your own unit. For shops, we stock the gearing, cases, seals, gaskets, axle and bearing kits to rebuild new or used Eaton rear ends for on highway, off highway, industrial, agricultural, construction, mining and logging work. If you need ten items for one rebuild, make one call.
Eaton ring gear and pinion identification
The ring gear and drive pinion are matched parts and must be replaced as a set. Both are stamped to help you identify them: the number of pinion teeth and ring gear teeth (for example 6-39), each part's own part number, and the matched gear set number, which is the same on the ring gear and the pinion. The word EATON on the pinion face marks a genuine Eaton part. Give us those numbers and we can match the set.
