Is the center drive shaft that comes with it long enough to fit in a long wheelbase chassis? Like for the Arrma Big Rock?

It will not. It will be too short. Go with metal as the torque in the Big Rock will be too much and it will break after a short while

Easy Peasy

A great kit, easy install and came complete. Even the stickers were great and not super cheap.

Perfect first upgrade

Excellent upgrade for the money. Brings the truck to life and handling is vastly improved. Easy enough to fit with my 8 year old son. Just remember that if you go further and fit the 3s brushless motor its worth investing in the centre driveshaft bearing support set as this is not included in either of the two boost boxes.
