Any particular reason for that, other than weight? Sure they will work?

They are skinny for weight reasons. We have done some stress tests and they have worked so far. If we need to we will change them out when we make this for the season. As long as they are alligned well, we shouldnt need them.

Take my advice, the last stage loks like it is about >125" which is much too thin. You may find that it works for a while but it will wear out prematurely due to very high gear tooth stress on that last stage.

Also, the smaller pinion gear should be wider than the larger mating gear to ensure the thinner teeth are always fully in contact.
