Hey I just bought the kraton 8s exb and have put the hobby wing esc and 800kv motor combo with a 8mm shaft into my truck and ordered a 40t pinion for it and was wondering will it work so I know if I wasted money on it or am I good. Meaning will the teeth match up because I have a 17t and the teeth on the gear don’t match up on the original spur gear that came installed on the truck. So am I good or do I need to order a new one.
