ARRMA Mini Kraton 3S 20CrMnTi Differential Upgrade 30/12T - MAKM1230FR by GPM  [MAKM1230FR]

High-load differential gear upgrade 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.

Choose this hardened 30/12T differential gear set to replace damaged bevels or to strengthen the driveline on ARRMA Mini Kraton 3S models; double-check pinion orientation and tighten fasteners with thread locker before driving.
