Overview
The G2 Axle and Gear Dana 44 5.38 ring and pinion set, part number G/22-2045-538 (model 2-2045-538), is a gear set with a 5.38 ratio for Dana 44 axles. G2 says its Performance Series ring and pinions are made for the increased loads of today’s performance vehicles.
The gears are forged from 8620 steel and precision machined to OE specifications. G2 says they are heat treated for durability and lapped for a smooth mating surface that helps reduce friction, noise and wear.
Key features
- 5.38 ratio ring and pinion set for a Dana 44 axle
- Forged from 8620 steel
- Precision machined to OE specifications, which G2 says makes setup easier and keeps noise at OE levels
- Heat treated for added durability
- Lapped to give the mating surfaces a smooth finish and reduce friction
- Performance Series design for increased loads
Before you set up the gears
A ring and pinion sets the final drive ratio, so a change in gear ratio alters how the axle turns at road speed and how hard it works under load. Lower ratios typically suit larger tires and towing, while higher ratios favor quicker response on the trail. Choose a ratio after you have settled on tire size and how the vehicle will be used most of the time.
Gear sets are normally replaced as a pair along with new pinion bearings, a crush sleeve and fresh gear oil. Old bearings run with worn gears can fail soon after the swap. Keep the work area clean, since small metal shavings in the carrier cause early wear.
- Confirm the ring gear tooth count against the carrier before buying
- Plan to replace the pinion and carrier bearings at the same time
- Use fresh gear oil suited to the axle

Vehicle fitment
It is a universal-fit ring and pinion set for the Dana 44 axle with a 5.38 ratio. Confirm fit for your vehicle’s year, model and trim before ordering.
Confirm the Dana 44 axle type, the carrier and the ring gear and pinion specifications for your vehicle before ordering.
Installation notes
Setting up a ring and pinion requires precise pinion depth and backlash measurements, so professional installation is recommended. Replace both gears as a set and follow the setup steps for this gear set. Use fluids and bearings matched to the axle. After installation, complete any break-in steps, check the fluid level and for leaks, and re-check fasteners after the first miles of driving. If you change gear ratio, check speedometer calibration and traction control settings.
