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

Pinion and spur parts for the Team Associated CR12 Ford F-150 Pick-Up RTR: fitted, and optional gearing supplied in the box
Component	Teeth	Pitch	Bore	Part number
Fitted at the factory
Pinion	11T	Not published	Not published	41043 (opens in a new tab)
Spur	Not published	Not published	Not applicable	41041 (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 (2.5 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

Associated prints the CR12 3-gear transmission at 13.98:1 and the axles at 2.43:1, for a 33.97:1 final drive (CR12 Toyota FJ45, Tioga and OverTrail press releases); the F-150 page itself prints only the 13.98:1 transmission.

The May 2018 CR12 parts list for the F-150 (40001, 40002) marks the 11T pinion (41043) as the part fitted and the 12T (41044) as optional.
The pinion drives a step gear (41041) whose tooth count Associated does not publish, so the spur and the ratio after the spur are left blank.
The CR12 Multi-Terrain tires (41054) measure 79.3mm (3 1/8 in) outside, per Associated's part page.
The Reedy CR380 motor is a 50-turn brushed motor, so it has no kV rating; the Reedy SC400 ESC manual rates the ESC for 2S to 3S LiPo, and the truck ships with a 2-cell 7.4V Li-Ion pack.
Associated prints the same 13.98:1 transmission and 33.97:1 final drive for the CR12 Tioga Trail Truck (40005, 40006) and CR12 OverTrail (40014C); their tires differ and their size is not published.
