With an 8.5T motor, I would start out with 84/20 gearing and go from there. Kyosho does not make an 84T spur so you will have to go to another brand for this configuration. If you have the Kyosho 82T spur, try 82/19 to start. Gearing is typically determined while at the track taking acceleration, top speed, and temperatures into consideration.

In MM configuration, RF2 is the correct hanger for the Front Rear. His configuration is not correct in this case. For the Rear Rear hanger, your truck has the Revolution Design aftermarket part for MM configuration. Hopefully the previous owner gave you all of the delrin inserts so that you can tune the rear suspension geometry.

In my experience with Kyosho, utilizing OEM parts is the best.
