Agreed. This is a common break point on many gearboxes.
However, I think that if a 4140 steel gear from vex pro is used it should hold up well. (Guessing it's a 14 tooth)

To OP: Why did you put the CIM motor mounts so high relative to the rest of the gearbox? It seems like you could have lowered the COG and made the gearbox smaller by lowering the CIMs to just above the pneumatic cylinder.
