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 | 25T | 32P | 3 mm | 10842 (opens in a new tab) |
| Spur | 47T | Not published | Not applicable | 10761 (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 an overall drive ratio of 7.36:1, and the owner's manual gear chart (p. 26) marks the 25T pinion on the 47T center-diff spur, 7.36, as the out-of-box setup.
- The manual works the ratio as spur / pinion x 3.92, the 47/12 ring and pinion in each differential.
- The parts list sets the 25-tooth pinion (10842) and the 47-tooth spur (10761) in regular type as stock, and both part pages list this truck as a stock fitment.
- Traxxas sizes this truck only as Mini and does not publish the Gravix tire's outer diameter, so the tire is left blank.
- The top speed shown is Traxxas's 40+ mph with the included 2-cell LiPo; it quotes 55+ mph with an optional 3-cell pack.
- No speed pinion comes in the box: the manual says the high-speed gearing is sold separately.
