1/12 and 1/10 Pan Car Geardiff 28T - Arrowmax AM-931004  [AM-931004]

Pancar geared differential for track tuning

The Arrowmax AM-931004 AM Pancar Geardiff 28T is designed for pan car layouts in 1/12 and 1/10 scales, suitable as a replacement or an upgrade where gear differentials are used. It installs inside diff housings made for geared internal assemblies.

Use this geardiff to obtain steady torque transfer through the driveline; the internal gearing influences throttle response and corner grip, which matters on carpet and smooth tarmac tracks. Altering internal gear count or mesh is a common method to refine handling for specific circuits.

Fitting advice: insert the geardiff into the vehicle diff case following the chassis manufacturer's orientation, set a correct mesh with the mating crown or bevel gear, and ensure bearing seats and housings are clean before completing assembly. Check drive shaft alignment and confirm there is no binding across the gearbox and suspension before putting the car on track.

Setup tips: small adjustments to mesh and preload affect balance; begin with the recommended mesh and make gradual changes while recording outcomes. Regular inspection of gear surfaces and mating components will reduce wear and preserve consistent behaviour.
