1/12 Pan Car Gear Diff Replacement for 6.35mm Axles - Arrowmax AM-931001  [AM-931001]

Precision Gear Diff for 1/12 Scale Pan Cars

The Arrowmax AM-931001 1/12 Pancar Geardiff Set is an aftermarket gear differential intended to take the place of ball-style diffs in 1/12 pan cars. It fits without conversion hardware and is optimised to provide predictable handling across different circuit surfaces.

Core construction uses a 6.35mm steel hollow shaft matching the common pan car axle standard, while the internal gear mechanism is tuned to reduce internal drag and limit the need for frequent service. The result is a diff that keeps its feel lap after lap.

Which Cars It Suits

The AM-931001 is made for 1/12 pan car chassis that use a 6.35mm hollow shaft layout; it conforms to common dimensions so most installs do not require chassis changes or adapter kits.

As a dedicated scale upgrade, the Arrowmax AM-931001 offers a simpler setup path than ball diffs while delivering stable, repeatable handling for club and competitive use.
