Pan Car 28T Geardiff Upgrade - Arrowmax AM-931004  [AM-931004]

Compact geardiff for pan car racing

The Arrowmax AM-931004 AM Pancar Geardiff 28T is a compact geared differential set built for 1/12 and 1/10 pan car layouts. It is intended as a replacement or tuning option where a geared diff is specified in the pan car differential assembly.

Fit this geardiff when you want predictable torque distribution through the drivetrain; in pan car setups the internal gearing influences throttle feel and corner traction on carpet or smooth asphalt club circuits. Changing internal gear count or mesh is a common tuning step for lap time optimisation.

Installation tips: place the geardiff into the chassis diff housing following the vehicle maker's orientation, set correct mesh with the mating crown or bevel gears, and ensure housings and bearings are free of grit before final assembly. Confirm drive shaft alignment and that there is no binding across the gearbox and suspension before the first run.

Tuning notes: small changes to gear mesh and diff preload will shift handling balance; begin with the chassis-recommended settings and log each tweak. Regularly inspect teeth and mating parts to avoid premature wear and maintain consistent performance.
