What pinion gear should I use on the Team Losi XXX-T Family?

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 XXX-T Family's stock 88T spur that is about 21T for 7.5–8.5T, 26T 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 XXX-T Family selected.

What is the internal ratio (transmission ratio) of the Team Losi XXX-T Family?

The XXX-T Family has an internal ratio of 2.43:1. Final drive ratio = spur ÷ pinion × 2.43. With the stock 88T spur, a 16T pinion gives an FDR of 13.37 and a 30T gives 7.13.

How many teeth is the stock spur gear on the Team Losi XXX-T Family?

88 teeth. Changing the spur moves every pinion's ratio at once; most racers leave the spur and tune with the pinion.
