Gear Set Identification
- The trademark shows the company logo and identifies the location of the manufacturing facility.
- A corresponding number marked on the differential ring gear and pinion identifies them as a matched set.
- The number of teeth on the pinion and the number of teeth on the differential ring gear result in gear ratio. A tooth combination of 41-11, for example, would indicate that the pinion has 11 teeth and the ring gear has 41 teeth that results in a 3.73:1 ratio.

- a hypoid design differential ring gear and pinion
- a 2-bearing overhung pinion mounting
- full-floating axle shafts
- a steel differential housing
- a front mounted removable 1-piece carrier housing

CAUTION:
Never mate a differential ring gear and pinion together that do not have the same matched set numbers. Always install a new matched set if discarding either the differential ring gear or the pinion.
