Heavy-duty 30/12T diff gear kit 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.

This hardened 30/12T differential gear set is recommended when replacing worn bevels or upgrading ARRMA Mini Kraton 3S drivelines; always confirm gear mesh and secure fasteners with thread locker before operation.

Does this kit match the stock gear geometry?

Yes. Tooth counts and module are selected to preserve the stock mesh geometry for ARRMA Mini Kraton 3S 1/16 setups.

What manufacturing material is used?

The gears are turned from 20CrMnTi steel and given a hardened black finish to resist wear under torque loads typical of brushless speed trucks.

Are parts pre-assembled to help installation?

Yes. The package accessories include pre-assembled gear sets; installers should still verify bearing seating and mesh alignment during reassembly.

Any advice for first-time installers?

Use a correct feeler for mesh checks, apply medium-strength thread locker to mounting screws, and run the car at low speed initially to confirm smooth operation before full use.
