Face it, you just can't leave it stock.  The speed pinion or those larger tires are calling your name and now you're stuck with a dreaded overheating motor and that stock fan isn't doing you ANY favors.  Upgrade today with our bolt-on adapter kit to mount (2) 50mm aluminum fans to cool it off and keep you bashing longer!  Choose with or without the fans for a complete plug and play setup to the factory Arrma 4686 heatsink.


Included in kit:

***Dual 50mm Rocket Fans are optional, please select the correct kit - Fans may be silver/black or red/black depending on availability***
