Pancar Geardiff Hub Upgrade for 1/12 - Arrowmax AM-931010  [AM-931010]

Overview of the 1/12 geardiff hub

The Arrowmax AM-931010 hub serves as an option replacement for 1/12 pancar geardiff systems, intended for tuners who swap and refine drivetrain components. It provides the mechanical link between the geardiff internals and drive outputs on 1/12 chassis.

Compatibility only covers 1/12 Pancar style geardiffs, so confirm the hub aligns with your diff casing and mounting interfaces before you proceed. Correct matching prevents misalignment and potential gear damage.

Fitting advice: follow your chassis service manual to remove the geardiff, check bearings and gear teeth for wear, then install the hub while setting the correct mesh and minimal axial play. Proper installation maintains consistent engagement and reduces noise.

Maintenance guidance: keep the diff area clean, check the hub interface for looseness, and ensure bearings and gears move freely after reassembly. Use this hub when experimenting with small preload and mesh changes to tune traction for different track surfaces.
