1/10 F1 Track Geardiff Kit - Arrowmax AM-931002  [AM-931002]

Overview of the 1/10 F1 gear differential

Arrowmax AM-931002 1/10 F1 Geardiff Set is a scale gear differential made to replace ball-type units in 1/10 F1 pan car setups. It locates into differential housings designed for a 6.35mm hollow shaft and aims to give steady mechanical behaviour without the frequent tuning that ball differentials demand.

The assembly uses a hollow steel shaft of 6.35mm diameter for the driveline interface, reflecting the common layout on many 1/10 F1 chassis. Where the existing shaft size matches, no adaptor is necessary and the kit replaces the ball-differential assembly directly.

From a setup viewpoint, the geardiff delivers a different torque split during cornering compared with ball units, producing repeatable engagement and reducing rebuild needs. That steadiness makes it handy for drivers focusing on consistent laps during practice or qualifying runs.

Install this geardiff where you want reduced service intervals and predictable mechanical behaviour; always check shaft size and differential housing fit before running and adjust driveline alignment as needed.
