1/10 F1 Gear Differential Upgrade - Arrowmax AM-931002  [AM-931002]

Technical notes for 1/10 F1 geardiff use

The Arrowmax AM-931002 1/10 F1 Geardiff Set is a gear-driven differential designed as a substitute for ball differentials in 1/10 F1 pan car configurations. It locates into differential housings that accept a 6.35mm hollow shaft and is intended to reduce the service cycle associated with ball-diff tuning.

The kit incorporates a hollow steel shaft with a 6.35mm diameter for the driveline connection, aligning with the common shaft layout used on many 1/10 F1 chassis. Where the shaft size and housing are compatible, the AM-931002 replaces the ball-differential assembly without needing adaptors.

From a setup and handling perspective the geardiff alters how torque is distributed during cornering compared with a ball unit, typically resulting in predictable mechanical engagement and fewer rebuilds. That stability is advantageous during practice and final setup adjustments before racing.

Use this geardiff where reduced maintenance and consistent mechanical performance are required; always confirm 6.35mm shaft compatibility, check housing clearance and ensure driveline alignment to avoid binding.
