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. Derived is worked out from gear tooth counts the maker publishes rather than printed as a ratio; the notes below say how. 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

Pinion and spur parts for the Element RC Enduro SE Sendero: fitted, and optional gearing supplied in the box
Component	Teeth	Pitch	Bore	Part number

Pinion	18T	48P	3.175 mm	1336 (opens in a new tab)Team Associated
Spur	45T	Not published	Not applicable	42316 (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. Linked part numbers go to the maker's or official distributor's page for that part.

How these numbers were settled

Element's product page prints an internal gear ratio of 12:1, and the manual's Stealth XF transmission build gives the tooth counts behind it: an 18T pinion (part 1336) drives a 45T/27T running gear, its 27T side turns a 50T slipper spur, and a 20T top shaft drives the 52T front and rear outputs through a 28T idler, which works out to 12.04:1.

The 45T running gear is the gear the pinion meshes with, so it is shown here as the spur.
Both axles use a 30T ring gear on an 8T pinion (3.75:1), so the transmission and axle ratio after the 45T gear is 18.06 and the total from motor to wheel is 45.14:1.
The transmission ships set to 1:1 front to rear; optional Factory Team gears overdrive the front 5.7% or 11.83%.
The tire diameter is left blank because Associated prints two sizes: 4.75 in on the product page, the press release and the manual, and 4.70 in on the PinSeeker tire's own part (42329).
The motor is a Reedy 16-turn 5-slot brushed crawler motor, so KV does not apply, and the Reedy SC480X ESC is rated for 2S to 3S LiPo.
The LiPo Combo (40107C) is the same truck with a battery and charger.
