spur gear

I have an ECX circuit 2wd and I'm looking to upgrade by pinion and spur. Currently I'm running the stock 87t spur and a 21t pinion I bought from Hot Racing. I would like to swap my pinion to a 26t but I don't know what size spur to upgrade to. What size spur is safe and how should i go about...

I replaced my spur and pinion gear is there a special adjustment

So I recently bought a 21t pinion cuz my esc was getting to hot with the stock 18t pinion the amp comes with. And for some reason the pinion screw keeps coming loose and striped the stock spur. I had the hot racing metal spur 87t and put that on and is now shaving the pinion!? I cannot win. I'm...

should I grease my metal piñon and spur gears. If so what type of grease

Well, I just ordered: -Hot Racing's Star Drive Steel Cv 2wd ECX drive shafts -32 pitch spur and pinion gears That will do it. Nothing left to upgrade, the only thing stock is the chassis and front shock tower. This truck has turned into something awesome!

Is it possible to run a 2wd spur gear on a 4wd truck or visa versa? Cant mesh my rc truck its a 4wd

Hey all! I just installed a 17.5t brushless motor (for stock racing) and I need to change the spur gear on my ECX Boost to something smaller (69-72 teeth). Does anyone know what other brands would work as a direct replacement (or with a minimum of drilling) for the stock ECX 87t spur? Thanks...
