Traxxas LaTrax Rally

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 applicable means the vehicle does not come with it, like the motor on a roller or the tires on a race kit, or does not have one, like a KV rating on a brushed motor. Not published means it exists but no source we could find prints it.

Gearing parts

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. Linked part numbers go to the maker's or official distributor's page for that part.

How these numbers were settled

The parts list sets the 14T pinion (7592) and the 54T spur (7591) in regular type as supplied, and both part pages list the Rally as a stock fitment, with the 9T and 10T pinions and the 60T and 61T spurs as accessories.

• The spec table prints 'Gear Ratio (Internal): 2.5:1', the ratio after the spur, so the overall ratio is 54 / 14 x 2.5 = 9.64.
• The motor is a brushed 370, so no KV applies.
• The cell rating is left blank because two Traxxas sources disagree: the owner's manual (2019) rates the LaTrax ESC for 5 to 6 NiMH cells only, while the current ESC part page (3045R) lists 5 to 6 NiMH cells or a 2S LiPo.
• The box includes a 6.0 V 5-cell NiMH pack.
• The manual lists the motor as 28-turn while the motor part page (7575R) calls it 23-turn.
• Traxxas does not publish a tire diameter for the stock slick tires on 12-spoke wheels (7572), so it is left blank.
• The differentials are packed with grease and the stock shocks are oil-less friction units, so no fluids are listed.
• Traxxas gives no numeric top speed, only an 'Under 30 mph' class.
