    Biggest Pinion Gear

    Would anyone tell me the biggest pinion gear can be used for the stock TRX4 Bronco?

    Check the manual. It says a 12T is the max recommended for the stock motor. That's up 1 tooth from the stock 11T. I just installed it on mine and I'm happy with a little more top end and low gear is still nice and strong.

    Thx. It is odd that I cannot find the gear chart in the manual, and only know the stock one is 11T.

    Just downloaded the manual from traxxas website and have found the different. The hard copy manual I got is up to Page 24. Not sure what is wrong.
