You can't fix this problem by replacing the gear. The pinion is overloaded and the best fix is a redesign that reduces load.

I agree they should fix the design to not load such a small gear/use on final reduction. But also I believe all the steel gears by VEX PRO are 4140 steel which should have a yield at 100ksi or more.
