I have a traxxas rustler 4x4 just put the traxxas rustler 4x4 vxl motor in it was wondering if i could also upgrade the pinion and spur gear without Wrecking anything and what would be a good one to change too

I just looked at the manual for the Traxxas Rustler 4x4 VXL, and it looks like that version of the vehicle came standard with a 54 tooth spur/11 tooth pinion. I would assume that would be a safe option. There are additional gearing options that can be found on page 27 of that manual. Here is a link on Traxxas' website for the Traxxass Rustler 4x4 VXL truck.

Here is a link to the Traxxas' contact information website, which includes information on how to call, email, or research information on the Traxxas web forums.

I hope this information helps

What are you trying to achieve? More acceleration? Top speed?
