Pancar Geardiff Internal Steel Insert Upgrade - Arrowmax AM-931011  [AM-931011]

Brief Overview of the Hub Insert

The Arrowmax AM-931011 hub insert is a replacement internal part for Pancar geardiff hubs. It provides a hardened contact surface at the hub to differential interface, intended to reduce local wear and stabilise contact points.

Fitment uses the stock hub retention and assembly procedure from your Pancar geardiff kit; the insert locates into the hub cavity and is fastened with the original retaining hardware. Confirm the insert matches your specific geardiff components and follow the kit assembly order.

In tuning and workshop use the insert supports repeatable contact geometry inside the geardiff, delivering more predictable differential response during setup and on-track adjustments. The part is suitable as a serviceable spare for 1/10 and 1/12 scale applications.
