1/12 Pan Car Geardiff Upgrade Compatible with 6.35mm Shafts - Arrowmax AM-931001  [AM-931001]

1/12 Scale Gear Differential Upgrade

The Arrowmax AM-931001 1/12 Pancar Geardiff Set is an aftermarket gear differential created to replace ball diffs in many 1/12 pan cars. It installs directly and aims to deliver steady, predictable traction on a wide range of track types.

The design centres on a 6.35mm steel hollow shaft that aligns with common pan car axle dimensions, and the internal gear diff is engineered for reduced internal friction and limited routine servicing. That makes setup more consistent for drivers chasing repeatable handling.

Fit Notes

This geardiff set is suited to 1/12 pan car chassis that accept a 6.35mm hollow shaft; it was dimensioned to match common pan car layouts so most fits will not require chassis modification.

As a purpose-built upgrade, the Arrowmax AM-931001 provides a maintenance-light option for racers who prefer a stable diff feel and straightforward setup tuning.
