Pro-Line PRO-Fusion SC 4x4 Kit

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

Pro-Line's instruction manual (p.21) states 'The Internal Gear Ratio of the PRO-Fusion SC 4x4 is 4:1', that the included Mod 1 spur is 44T and that a 16T Mod 1 pinion is included.

• The total is 44/16 x 4 = 11.0, inside the manual's chart range of 12.6 (14T) to 8.4 (21T).
• The kit ships without radio, ESC, motor or battery, so KV and cell rating do not apply.
• Tires are not included (the manual lists several 2.8 and SC options), so the tire size is left blank.
