1/10 F1 Race Geardiff Assembly - Arrowmax AM-931002  [AM-931002]

1/10 F1 geardiff summary for racers

The Arrowmax AM-931002 1/10 F1 Geardiff Set is a gear-style differential intended to replace ball differentials in 1/10 F1 pan cars. It integrates into housings that accept a 6.35mm hollow shaft and is aimed at drivers seeking a robust, low-service differential for race-day practice.

The unit uses a hollow steel shaft sized at 6.35mm for the driveline interface, matching standard configurations on many 1/10 F1 layouts. For installs that already use that shaft diameter, the kit replaces the ball-differential directly without extra components.

In terms of handling the geardiff changes how drive torque is shared during cornering compared to ball units, offering more predictable mechanical engagement and fewer rebuilds. That predictability is useful for drivers fine tuning setups before competition.

Ideal where you want reliable, repeatable differential behaviour with reduced maintenance; confirm the 6.35mm shaft fit and check for adequate housing clearance and driveline alignment prior to running.
