What about when you have an Ultimate60 cover?Does it hold more oil? The level plug sits pretty far above the axle centerline.

Yes it does hold more, almost three quarts. I use Royal Purple 85W-140 no leaks and my rear end seems happy and cool.



GARY,thats some heavy oil. i think that might have some extra drag on your rear.
i think the royal purple 75w -90 might have been a better choice.
