Arb air lockers and 4.88 gears

2020 trd sport arb lockers and 4.88 gears what gear oil can I use I have some valvoline 75w90 ls gear oil is it safe for arb lockers

 

Here's an ARB spec sheet I pulled off of google...take it with a grain of salt since we don't know what application it's based on. I think any gear oil without the LS additive will be fine.

I've got e-lockers and have used the fluid you posted above as well as the 85w-140 that ECGS recommends. I haven't noticed any performance or sound difference with either one. If you want better advice you could call up a gear shop like ECGS or ARB directly.

 

Thanks for reply
