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 | 21T | 48P | 3 mm | 2421 (opens in a new tab) |
| Spur | 90T | 48P | Not applicable | 4690 (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 owner's manual gear chart (p. 25) marks the 21T pinion on the 90T spur, 11.66, as stock, worked as spur / pinion x 2.72 for the Magnum 272 transmission.
- The parts list sets the 21-tooth pinion (2421) and the 90-tooth spur (4690) in regular type as stock, and both part pages list this truck as a stock fitment.
- Traxxas's product page instead prints 'Gear Ratio (Internal): 2.72 (final drive: 12.34)'; 12.34 is not a cell in the manual's chart and does not match the stock gears, so the 11.66 that the manual, parts list and part pages agree on is shown here.
- The stock tires are Terra Groove on 2.2 in chrome wheels (3663X, 3665X); Traxxas does not publish their outer diameter, so the tire is left blank.
- The top speed shown is Traxxas's 30+ mph with a 7-cell battery; the battery and charger are sold separately.
