Savage Diffs

wouldn't running the motor in reverse also help eliminate the slipper nut from coming loose?

That and flipping the diffs to ensure the truck goes the correct direction when the motor rotation is changed.

I'm calling this mod a success.

I've got 2 dozen runs or more on these diff cups and there are no visible signs of internal gear or cup wear. For me, the Vorza cups are a very good upgrade that is actually less than half the price of the stock cups (win win).

Results will probably vary depending on your driving style. I am heavy on the throttle, do some mild jumping, but generally don't do hard starts and avoid back flips all together.

One other thing I did to my diffs that may seem weird and perhaps even a little crazy . . .
After several months of use, the bearing holder on the BP ring gear wore down to the point that it was slipping inside the bearing. Fix: after shimming the diffs, I put a very thin coating of red loctite on the bearing holder before putting the bearing on for good (I was careful not to get any loctite inside the bearing). The red loctite prevents the bearing from slipping on the ring gear and all it takes is a slight amount of pressure with a couple of flat head screwdrivers to pry the bearing back off when it comes time to change it out. I did this to the cup side bearing as well to prevent it from ever getting worn down.

If the bearing ever seized up, this could be a problem, but most likely the inner sleeve would just detach from the raceway and free spin, as I have seen happen a dozen times before with the 10x16 bearings. No telling which part would give out in the highly unlikely scenario of the bearing locking up and not falling apart (probably the sacrificial lock pins inside the cup but your guess is as good as mine). Try this one at your own risk.
