Check before you order
- Ring gear size and pinion: this set is 11.25 inch with a 37-spline pinion, so match it to your Dana 80.
- Carrier: confirm your carrier is the 4.10 and up type before ordering.
- Yukon's page does not list a rotation or a specific list of vehicles for this ratio, so confirm fitment against your axle rather than the truck model.
What's included
You get the ring and pinion. Everything else for the rebuild, including bearings and seals, is separate.
Installation
A proper setup means checking pinion depth, backlash and contact pattern. This is heavy-duty axle work, so use a shop with gear setup tools if you do not have them.
Warranty
Yukon puts a one-year warranty on its ring and pinion sets and also describes a Y.E.S. plan that covers the gear set. Confirm the details with Yukon.
