It depends on your motor and the track. Racers in the 1/10 2WD street stock (dirt oval) class run a 20–28 tooth pinion in most setups, usually on a 78T spur for a final drive ratio near 7.98. 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 Slash Street Stock selected.
What is the internal ratio (transmission ratio) of the Traxxas Slash Street Stock?
The Slash Street Stock has an internal ratio of 2.72:1. Final drive ratio = spur ÷ pinion × 2.72. With the stock 86T spur, a 18T pinion gives an FDR of 13.00 and a 30T gives 7.80.
How many teeth is the stock spur gear on the Traxxas Slash Street Stock?
86 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
