I used this to replace the front and rear difs on my Ranger Raptor. The best gear oil for my application

I had a skip in the transmission in my 2022 Explorer King Ranch with 60k miles. I changed trans, both differentials, and transfer case fluids with amsoil products and it runs better than when I bought it and the trans issues are completely gone!

Honestly, never knew something could take such a beating. Between towing, and off roading, has never left me wondering.

It is a great product. And the easy squeeze packet is fantastic to use

It's always a great feeling knowing I have Amsoil in my differentials. Whether I'm towing my 40ft fifth wheel or 6 wheeling my F-350 Dually 4x4. Amsoil has got my back!

Bought enough to do both front and rear diffs in my Ram 2500 4wd. Squeeze packaging made it easy to fill.

Amsoil is the best straight out

makes shifting much better

It only makes sense and just a few dollars more to get the best performance and protection for your vehicle.

Put this in my 2015 camaro ss dif. It seems to work so far

I had some significant noise coming from my driveline, I have a 2016 Ram 1500 4x4 and figured it had to be the differentials, it was, used the severe gear and noise gone. Very quite ride now. I pull a compact tractor frequently to severe gear was the way to go.

Quality product, stellar reputation, easy to use!

Love the squeeze containers, convenient, fast, and clean fluid change. Peace of mind knowing I won’t have to do it again for a while with the Amsoil fluid.

Running this on all my trucks for over 200000 miles on heavy duty towing,, very minimal wear on my differentials. Extremely recommended!!

Great product easy to use.

Used for Transfer case and Rear Differential on a 2019 Rav4 adventure model. It's been installed 2 weeks now and driven 1,000 miles. There is no loud noises and it's still running, so that's a good thing. Any difference?, none I can see. It will be when I change it out again to see if any changes in the color or smell. As for the soft packs, I should have got the quart bottle. I use a pump to fill the cases back up and this was not working, guess it could be my pump, but I filled a container and was able to pump out of that. Anyways, this is supposed to be great stuff, we will see.

The bags made the job super easy!

Severe gear in diff on Challenger R/T, definitely smoother and quieter. OE gear oil looked like metallic paint at only 4,000 miles

I like the review on the oil
