Improved epoxy: Uses high temperature epoxy that is stronger than OEM, eliminating the possibility of magnet detachment.

High grade steel capping: Prevents heat and friction from degrading the epoxy attaching the magnets. Though extremely unlikely, if a magnet did ever come loose, it would remain in the sleeve preventing contact with the stator.
