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.
Gearing parts

| Spur | 78T | 48P | Not applicable | 365878 |
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.
How these numbers were settled
Carpet version of the 2026 XB4, with a 78T/48P slipper clutch spur (#365878) in place of a centre diff; XRAY's features page states that the XB4C now includes the smaller 78T slipper spur.
- The front and rear diffs use the 40T bevel gear (#364940, marked included, with a 41T as an option) against a 16T drive gear (#365127), so the after-spur figure is worked out as 40/16 = 2.5.
- XRAY prints no ratio for the 2026 kit.
- Motor, pinion, speed controller and tires with inserts are not included.
