Description

Vehicle Fitment

• Dana 44 differential (front or rear), standard rotation, 26-spline pinion
• The Dana 44 has been used across a very wide range of vehicles since the mid-20th century, including Jeep, Ford, GM, and Dodge trucks and SUVs, as well as common off-road axle swaps

Fitment Notes

• I was not able to confirm a specific, reliable vehicle-by-year application list for this exact ratio/spline combination from independent sources - every listing I found describes this part by axle spec only, not by vehicle. If you need confirmation for a specific vehicle, verify directly with Yukon/USA Standard Gear or by measuring your differential
• Standard rotation only - not for reverse-rotation Dana 44 applications, which require a different gear set
• 26-spline pinion; confirm your pinion spline count matches before ordering
• This is a ring & pinion gear set only - it does not include bearings, races, shims, or seals; pair it with a separate install or master overhaul kit for a complete gear swap

Product Description

The Yukon ZG D44-538 is a high-performance ring & pinion gear set for the standard-rotation Dana 44 differential, one of the most widely used front and rear axle designs in American truck and off-road history. At a 5.38 ratio, this is an aggressive, off-road-oriented gear set typically chosen by builders running larger tires who need to restore proper torque and drivability after a lift or tire upgrade.

Built with a 26-spline pinion, 10 ring gear bolts, and an 8.500" ring gear diameter to match factory Dana 44 specifications, this set is engineered for quiet operation and straightforward setup. Because the Dana 44 has been produced in numerous spline counts and both standard and reverse-rotation configurations across its long history, confirming your exact axle specification - not just the model name - is the essential step before ordering.

This is a gear set only, not a full install kit - it doesn't include the carrier bearings, pinion bearings, shims, or seals needed to complete a gear swap. Pair it with an appropriate master overhaul or bearing install kit for your specific application. Installation requires differential disassembly and proper backlash and pinion depth setup, so it's best handled by an experienced DIY installer or a differential shop.
