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
| Component | Teeth | Pitch | Bore | Part number |
|---|---|---|---|---|
| Fitted at the factory | ||||
| Pinion | 10T | 32P | 3 mm | 6746 (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
Traxxas's product page prints 'Gear Ratio (Internal): 15.36:1', and the owner's manual gear chart (p. 24) marks the 10T pinion on the 54T spur as the out-of-box setup, worked as spur / pinion x 2.85 = 15.39.
- The parts list sets the 10-tooth pinion (6746) and the 54-tooth spur (3956) in regular type as stock, and both part pages list this truck as a stock fitment.
- It shares its gearing, BL-2s 3300Kv system and published dimensions with the Stampede 4X4 BL-2s, and differs in its BIGFOOT No. 8 body and its Terra Groove tires on white wheels (3663-WHT).
- Traxxas does not publish the Terra Groove tire's outer diameter, so the tire is left blank.
- The stock BL-2s ESC takes 6 or 7-cell NiMH or a 2-cell LiPo.
