1/12 1/10 F1 Pan-Car Geardiff Upgrade Supergear 64P 80T - Arrowmax AM-931018  [AM-931018]

Overview of the pancake geardiff

The Arrowmax AM-931018 geardiff kit is presented as a replacement or upgrade for pancake style drivetrains on 1/12, 1/10 and F1 scale pan cars. Supergear 64P 80T indicates the pitch and tooth count family you should match to your existing pinion and spur gears, not a statement about material.

Role on a pan chassis: this set supplies internal gears and associated hardware to assemble a gear-based differential compatible with flat pan layouts. Modifying diff mesh and backlash with these gears helps tune traction and steering balance on smooth track surfaces commonly used in pan-car racing.

Installation tips: check tooth count and pitch against your gearbox parts, clean components and apply light grease to the gear faces, use a thin shim to set mesh, and confirm there is no binding through full travel. Refer to your chassis manual for torque specs and bearing positioning as this note covers fit and tuning guidance only.
