Stock is as the vehicle ships. Calculated is worked from the stock figures on this page rather than stored beside them, so the two cannot drift apart. Not published means it exists but no source we could find prints it.
Gearing parts

|---|---|---|---|---|
| Fitted at the factory | ||||
| Pinion | 12T | 32P | 3 mm | 3942X (opens in a new tab) |
| Spur | 54T | Not published | Not applicable | 3956 (opens in a new tab) |
Tooth counts are the ones in the specifications above. Pitch is given as metric module (Mod 1, Mod 0.8) or diametral pitch (32P, 48P). They are different standards and are not interchangeable, even where the numbers look close. Bore is the pinion’s hole, listed separately from the motor shaft (3 mm on the stock motor). Linked part numbers go to the maker's or official distributor's page for that part.
How these numbers were settled
The product page prints 'Gear Ratio (Internal): 12.81:1', which is the overall ratio, not the transmission alone.
- The owner's manual gear chart (p. 23-24) marks a 12T pinion on the 54T spur as the out-of-box gearing at 12.83:1 and gives the formula spur / pinion x 2.84.
- The parts list sets the 12T hardened steel pinion (3942X) and the 54T spur (3956) in regular type as supplied, and both part pages list this truck as a stock fitment.
- The spur is described as '0.8 metric pitch, compatible with 32-pitch', so its pitch is left blank.
- Traxxas does not publish a tire diameter for the stock Talon EXT 2.8 inch tires (6769), so it is left blank.
- The BL-2s ESC takes a 6 or 7 cell NiMH pack or a 2S LiPo.
- Traxxas gives no numeric top speed, only an 'Under 30 mph' class.
