These Upper motor mounts are for Hybrid/IDEX on VCore4 only and are not needed for CoreXY implementations. This is why we are selling them separately instead of with the motor mount upgrade.
Made from 6061, these upper mounts improve the rigidity and stability of the Hybrid/IDEX implementation over the stock setup.
HYBRID/IDEX NOTE: For Hybrid/CoreXY, @Ross13 (discord) has graciously documented the install process and what additional items you will need to upgrade to Hybrid/CoreXY. Please see the instructions linked here for a full list of hardware needed.
