ARRMA Mini Kraton 3S Front Differential Upgrade 12/30T MAKM1230FS by GPM  [MAKM1230FS]

Front differential for ARRMA Mini Kraton 3S

This replacement front differential assembly fits ARRMA Mini Kraton 3S and carries the model number MAKM1230FS. The unit uses 20CrMnTi steel for the internal gears and 7075-T6 aluminum for the housing parts, with spiral-cut ring gearing made up of a 30T large bevel and a 12T input bevel at 0.8 module. The differential is delivered fully assembled and includes bearings so it is ready to install.

The 12/30T gearset and 0.8 module are matched to driveshafts that accept 2 mm pins; the large and small bevel gears have a hardened black surface finish to increase wear resistance under heavy loads. This part is intended as a direct replacement for factory items ARA-3294 and ARA-2672 in compatible ARRMA Mini Kraton 3S kits.

Diff oil is not included. Recommended starting points are front 50K CST, rear 30K CST, and center at 500K CST or 1000K CST depending on handling preference. Fasteners noted as pre-assembled arrive in place, and using thread locker on screws is advised to prevent loosening during high-load running.

If you need to restore or strengthen the front end of a Mini Kraton 3S, this front differential supplies hardened gears and alloy support components sized for the ARRMA 1/16 platform; plan to add your chosen diff oil and secure screws with thread locker during installation.
