Transfer case fluid and differential fluid viscosity and capacity notes:

• If you are choosing to replace only one of your differential gear oils or just change the transfer case fluid. Please adjust the cart quantity of the gear oils or transfer case fluid in accordance with your desired differential or transfer case fluid fill capacity and fluid quantity.
• Our kits are based on factory recommendations. We always suggest consulting your service manual or the vehicle owner’s manual to confirm the specific gear oil requirements for your exact vehicle application.
• Regarding using the recommended gear oil in Ram 1500 rear differential. From our understanding, there is some possible conflicting information with paper and digital documentation depending on the year of your truck and whose service manual recommendations you are using. Also, the country you are in may have different gear oil recommendations. The following information is for USA models only.
• The current recommendation for the rear differential gear oil in all 2012-2016 Ram 1500 models is going to be a 75w140 GL-5. We do offer a few 75W-140 GL-5 LS gear oils that include LS friction modifiers in the formulation. No extra additives need to be added.
• Regarding the 2017 and newer rear differential gear oil type. At the time of this comment, the current recommendation for all 2017-2020 Ram 1500 rear differentials is a 75w-90 GL-5 gear oil. This was the original recommendation regardless of the differential type. After late 2020/2021 the original recommendations go to identifying a specific differential type for the type of gear oil. 3.92 being 75W-140 GL-5, 3.92 tow being 80w90 GL-5, and 3.21/3.55 being 75W-90 GL-5. Note, that this is a 2019 Ram 1500 model year being used in the DIY, hence the 75W-90 GL-5 is used. See related items below for 75w140 and 80w90 gear oils if you require these.
• Unfortunately, this might add more confusion. We always suggest consulting your service manual or the vehicle owner’s manual to confirm the specific gear oil requirements for your exact vehicle application. For all practical purposes the viscosity profiles of both the 75w-90 and 75w-140 will work for all Ram 1500 rear differentials. If you want to minimize rolling resistance for improved fuel economy, use a 75w-90 GL-5, and if you tow heavy on a regular basis use a 75w-140 GL-5.
• To confirm your differential type. 3.21 or 3.55 rear differentials have the drain and fill plugs located on the right passenger side of the differential. If you have a 3.92, the rubber fill plug should be in the rear differential cover. You may also contact your dealer to confirm the rear differential type.
