ARRMA Mini Kraton 3S Front Diff 20CrMnTi+7075 12/30T MAKM1230FS by GPM  [MAKM1230FS]

Upgrade front differential for Mini Kraton 3S

This front differential fits ARRMA Mini Kraton 3S and is listed under model MAKM1230FS. It combines 20CrMnTi steel internal gears with 7075-T6 aluminium housings and uses a spiral-cut 30T large bevel paired with a 12T input bevel at 0.8 module. The unit arrives assembled and includes the necessary bearings for immediate installation.

The gear ratio of 12/30T and the 0.8 module are suitable for driveshafts that use 2 mm pins; the bevel gears have a hardened black finish to improve load endurance. It is intended to replace factory items ARA-3294 and ARA-2672 in supported ARRMA Mini Kraton 3S kits.

Diff oil is not supplied. Suggested baseline viscosities are front 50K CST, rear 30K CST, and centre 500K CST or 1000K CST depending on preferred handling. Small fasteners arrive pre-assembled where noted, and applying thread locker to exposed screws is recommended to avoid loosening under heavy use.

For Mini Kraton 3S owners wanting a tougher front end, this front differential supplies hardened gearing and alloy support parts matched to the ARRMA 1/16 platform; be ready to add diff oil and secure screws during fitting.
