For ARRMA Mini Kraton 3S 1/16 20CrMnTi 30T/12T Rear Gear Set MAKM1230R by GPM  [MAKM1230R]

Aftermarket rear differential gears for Mini Kraton 3S

This replacement rear differential gear set is made for ARRMA Mini Kraton 3S 1/16 scale brushless trucks. The package includes a spiral-cut 30T bevel ring and a 12T pinion in 0.8 module so the gears align with the original geometry for direct replacement on the listed models.

Built from 20CrMnTi steel with a hardened black coating, these gears are intended to offer greater wear resistance in demanding RC use while preserving smooth engagement thanks to the spiral-cut profile. The set replaces factory parts ARA-3294+ARA-2672 and is sold as the matched ring and pinion.

Installation advice: the gears arrive pre-assembled; apply medium-strength thread adhesive to fasteners to reduce loosening risk during aggressive running. Verify backlash and mesh with the stock 0.8 module and test differential action at low speed first.

Select this GPM ring and pinion when a hardened steel upgrade is required to maintain stock fit and increase longevity under heavy RC use.
