- Fits front or rear Dana 60 axle positions
- 8620 steel gears
- CNC machining throughout
- Computer controlled heat treatment
Front and rear Dana 60 use
Dana 60 axles are heavy duty housings, and the same ring and pinion design can be found in front and rear positions. Because front and rear gears run at different driveline angles, the pinion depth and carrier shims differ between them, so the position must be confirmed before setup. A 3.73 ratio gives strong low speed pulling, though tire size still changes the final result.
Gears that see frequent low speed work benefit from careful break-in, while highway use puts less stress on the teeth. Regular axle fluid changes help keep the mesh surfaces protected, and a fluid check after a water crossing or a hard off road outing is a sensible habit.
- Confirm front or rear position before ordering the set
- Replace bearings and seals when the housing is open
- Use the correct gear oil for the axle
- Check pinion depth and backlash after installation
