ARRMA Mini Kraton 3S Spiral-Cut Differential Gears 30/12T MAKM1230FR by GPM  [MAKM1230FR]

Upgraded spiral-cut diff gears compatible with Mini Kraton 3S

This RC-scale gear set replaces the factory differential gears ARA-3294+ARA-2672 and is intended for ARRMA Mini Kraton 3S 1/16 models. Components are machined from 20CrMnTi steel and receive a hardened black surface treatment to raise wear resistance under heavy drivetrain loads. The kit uses a spiral cut ring gear paired with larger bevel gears (30T) and 12T pinions, 0.8 module, preserving mesh geometry and gear ratio matching for the stock drivetrain layout.

All supplied gears and pinions are delivered pre-assembled inside the package accessories, simplifying swap-in work during maintenance or upgrade. For longer-term stability it is recommended to apply thread locker on mounting screws and verify gear mesh and bearing seating during reassembly. This part is an RC accessory and is not intended for real vehicle use.

Fit this hardened 30/12T gear set to restore worn internal bevels or to upgrade drivetrain durability for ARRMA Mini Kraton 3S units; always check mesh clearance and secure screws with thread locker before use.
