I have a newer Kraton EXB and these are the diffs that come on the front and rear. On my Kraton these diffs have proven to be dependable. My Notorious, standing backflips, curb backflips, speed bump backflips, chain link fence double back flips, and never ending using the throttle to flip it back on to its wheels. On my Notorious the EXB diffs have proven themselves tough and have shone no sign of gear slippage under high loads. The EXB diffs out of the bag are set up for the front. To run them in the rear you have to change the order of the slipper plates to make the diff more open. Instructions for this can be found in the Kraton 6s EXB or Outcast 6s EXB manuals online.
I consider Arrma EXB LSD diffs the gold standard for 6s trucks.
Notorious dead sailor list; BLX front and rear ( lots of gear slippage but no broken teeth), Hotracing gears and cases front and rear (they disintegrated fast).
