So Eddie, what would you recommend in a PR 44 and PR 60 with 5.13 and ARB locker?
How many quarts for PR60?
First off, I would stick with standard dino fluid and being that you're in SoCal, you could go up to a 75W140 or there about especially in the rear. Not as needed up front but I don't think it'll do any harm. As far as how much goes, you want enough in to reach the base of the axle tubes. I would use a bent zip tie as a dip stick to help figure this out.
