Going to change my front and rear diff fluid but wanted to check and make sure that this fluid will be ok for both front and rear

But it says it has friction modifiers in it

 

 

Truck has the G80 RPO code

If you buy, see if it is sold in 1 qt squeeze packs. Super easy to refill the diffs

All I use

I used the Mobil Delvac 75w90 for my 2016. It took 4qt 12oz total to fill both diffs. I wanted an oil that doesn’t have the limited slip additive in it to prevent any issues with the G80 locker.

Kyle77, This will work just fine.  No issues.  I used it in my 2002 Silverado for over 200k miles and now in my 2019 Silverado.     The easy packs makes installing it nice and easy with no mess.
