Yukon high performance replacement ring & pinion gear set, Dana 80, 5.38 ratio

This is the Yukon 5.38 ring and pinion set, YG D80-538, a high performance replacement gear set for the Dana Spicer 80.

Fitment

• Axle: Dana Spicer 80
• Ratio: 5.38
• Pinion: 37 spline
• Ring gear: 11.25 inch, 12 bolts

5.38 is the numerically highest ratio in this group of Dana 80 sets, so it gives the most gear reduction.

Carrier and fitment notes

Yukon's page for this ratio does not name a carrier range. Retailers put the Dana 80 carrier break at 4.10, so verify what is in your axle before ordering.

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: no carrier range is stated for this ratio on Yukon's page, so confirm your carrier and its ratio range first.
• 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.
