The Y62 2017-2021 Nissan Armada and Z62 2011-2023 Infiniti QX56 / QX80 equipped with the 7 speed transmission are geared at 2.93 ratio from the factory. The front and rear differentials from a tow package 1st gen Armada (2003-2015) are geared at 3.36 ratio. If you're lifting your Y62 and running larger tires or doing a lot of towing / hauling and notice your transmission gear-hunting, changing ratios to 3.36 is an excellent upgrade. With this adapter the front and rear diffs from a 1st gen Armada are a direct bolt-in and result in replacing the weaker R180A front differential with the stronger M205 front differential. They're commonly available in junk yards and pick-and-pulls.
Components required for this upgrade on your vehicle -
- M205 Front Differential from 1st Gen Armada or 1st Gen Titan in 3.36 Ratio (3-Rib M205 recommended)
- R230 Rear Differential from 1st Gen Armada in 3.36 Ratio
- Front Driveshaft from 1st Gen Armada or 1st Gen Titan

Notes:
- This adapter will not work with vehicles equipped with the 9 speed transmission (2022+ Nissan Armada)
