It depends on your motor and the track. Racers in the 1/10 4WD truck class run a 16–25 tooth pinion in most setups, usually on a 81T spur for a final drive ratio near 10.93. Hotter motors (lower turns, higher Kv) take a smaller pinion; tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the Rustler 4X4/VXL selected.
What is the internal ratio (transmission ratio) of the Traxxas Rustler 4X4/VXL?

How many teeth is the stock spur gear on the Traxxas Rustler 4X4/VXL?
