ARRMA Mini Kraton 3S 20CrMnTi steel front and rear differential gear 30/12T set by GPM MAKM1230FR  [MAKM1230FR]

Front and rear diff gear set for 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.

Use this steel 30/12T differential gear set when replacing worn bevels or when you need a direct-fit, hardened replacement for ARRMA Mini Kraton 3S drivelines; confirm correct pinion orientation and secure fasteners with thread locker before running.
