SuperLube is 100% synthetic and friendly on rubber o-rings and ideal for metal on metal contact. We do maintenance on our gear boxes once a year and nice thing about it, it doesn't leak like oil and its cheap when you buy a large tube of it.

The other thing you need to know is, grease is more effective on open gears like the ones in the diffs which is made from cast aluminum and needs good lube to keep them from wearing out. Well, we just eliminated our aftermarket diff cases with this info for you guys.
