Yukon high performance replacement ring & pinion gear set, Dana 80, 4.11 ratio

This is the Yukon 4.11 ring and pinion set, YG D80-411, a high performance replacement gear set for the Dana Spicer 80.

Fitment

• Axle: Dana Spicer 80
• Ratio: 4.11
• Pinion: 37 spline
• Ring gear: 11.25 inch, 12 bolts

4.11 is a mid-low ratio for the Dana 80 and comes right at the carrier break.

Carrier and fitment notes

Retailer listings give the Dana 80 carrier break as 4.10. A thick 4.11 gear is used on a 4.10 and down carrier, and Yukon lists that as a separate part (YG D80-411T), so this listing is the 4.11 without the T.

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 ratio range. If the carrier is a 4.10 and down type, look at the thick 4.11 set (YG D80-411T) instead.
• 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

This is the gear pair alone. Bearing kit, seals and install hardware are sold separately.

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 lists a standard one-year warranty on its ring and pinion sets and promotes a separate Y.E.S. protection plan. Check Yukon for the current terms.
