Differential Gear Oil weight

[TuckerTravis]

I'm sure the answer to this is on here somewhere but I havent found it. What is the front and rear differential gear oil weight recommendations. I was wanting to put royal purple max gear in it but dont know the weight to use.

Front 80-90w rear 75-140 synthetic. Both diff covers must be removed to drain and the fronts not fun.

Best Differential Oil

What are the best front and rear differential oils?

I use Amsoil and added the bigger rear diff cover. It has a drain plug, dipstick, finned and holds 2 more quarts.

Is the amsoil pretty good?

Interesting. Could you tell us a little more about the rear cover mods
you have done.

Basted on the brief discription you gave, it's like waving a bone in front
of my dog. He want more and so do I.

Thank for any information provided. Look forward to your reply

Amsoil is one of if not the best, but then again, I am biased. You can check them out for yourself below. If you would like more information about them, feel free to let me know.
