The shockproof gives you NO problems what so ever, even in your axles with Trac Loc diffs (or any other clutch plate type diff)??
Dave at RL has told me this stuff has some moly in it, which IS a NO NO for these types of diffs to function properly.
The trac-lok needs the ford labelled friction modifier when you use any other type of gear oil,red line basically already has it in,so I don't add any friction modifier when changing fluids.
And to answer your question I put 100000kms on that 3.90 gear set so far and I'm still burning out with both tires,so if it was going to cause an issue it would have long before now.
I am using it in my chevs diff as well and no issues. Both mustangs have it.
So nope,not a single solitary issue thus far
