What pinion gear should I use on the Traxxas Stampede 2WD?

It depends on your motor and the track. In the 1/10 2WD truck class, racers gear by final drive ratio: 7.5–8.5T near 10.14, 13.5T near 8.27. On the Stampede 2WD's stock 90T spur that is about 24T for 7.5–8.5T, 30T for 13.5T. Tight tracks gear down, open tracks gear up. For a starting pinion matched to your motor, use the So Dialed Pinion Recommender with the Stampede 2WD selected.

What is the internal ratio (transmission ratio) of the Traxxas Stampede 2WD?

The Stampede 2WD has an internal ratio of 2.72:1. Final drive ratio = spur ÷ pinion × 2.72. With the stock 90T spur, a 16T pinion gives an FDR of 15.30 and a 30T gives 8.16.
