Face it, you just can't leave it stock.  The speed pinion or those 3.8" Pro-lines are calling your name and now you're stuck with a dreaded overheating motor and that small stock fan isn't doing you ANY favors.  Upgrade today with our bolt-on adapter kit to mount (2) 40mm aluminum fans to cool it off and keep you bashing longer!  Choose from our Finned Rock Guard or the sleek Velocity Stack Rock Guard, with or without the fans for a complete plug and play setup.

Included in kit:

***Dual 40mm fans are optional, please select the correct kit - fans may be silver/black or red/black depending on availability***

- Adapter plate with brass threaded inserts (mounts to stock Arrma 4074 heat sink) used in most 6s trucks

My Fans Never Looked so Good

This item came with the double fan base plate and the velocity stack cover piece. Everything fit perfectly and looks amazing. Shipping was super fast as well. A+

Keep your motor cool!

Love this dual fan setup by Campsite Carbon! I liked it so much, I bought another setup for my 6s Notorious! These fans scream! Fast shipping and a US Based company! Can't go wrong with an order from Campsite Carbon!
