1/10 F1 Geardiff Replacement Set for Pan Cars - Arrowmax AM-931002  [AM-931002]

1/10 F1 geardiff technical brief

The Arrowmax AM-931002 1/10 F1 Geardiff Set is a compact gear-type differential built to replace ball differentials on 1/10 F1 pan cars. It fits into differential housings that accept a 6.35mm hollow shaft and is aimed at drivers who want steady mechanical differential behaviour without the regular tuning cycle of ball units.

The kit features a hollow steel shaft with a 6.35mm diameter for the driveline connection, matching the common arrangements used across many 1/10 F1 chassis. If your car already uses that shaft size, the AM-931002 installs as a direct replacement without additional adaptors.

On the track the geardiff alters torque distribution compared with ball differentials, giving more predictable engagement and cutting down on rebuilds and shimming. That makes it useful for practice sessions and race prep when consistent lap-to-lap performance is the priority.

Choose this geardiff when you need a lower-maintenance, mechanically consistent differential; always confirm 6.35mm shaft compatibility and check differential housing clearance and driveline alignment during fitment.
