80/90 if running conventional oils... I think the synthetic we use in place of it is like a 75/140... something like that.

Re: Specified weight of gear lube?
I think the 80/90.Also important is to use the additive if you have a no-slip.The name of it escapes me at this moment but someone should chime in.

Re: Specified weight of gear lube?
Original was 80w-90 and if you had posi you needed to add a friction modifier to eliminate chatter. I will be running 75w-90 Royal Purple in mine when I re-gear and it already has friction modifiers in it for posi...if I was really going to rage on it I would run 75w-140 synthetic
