ARRMA Mini Kraton 3S 1/16 Rear Differential Ring & Pinion 30T/12T MAKM1230R by GPM  [MAKM1230R]

Replacement ring and pinion for Mini Kraton 3S rear diff

This aftermarket rear differential gear set is intended for ARRMA Mini Kraton 3S 1/16 scale brushless trucks. The kit contains a spiral-cut 30T bevel ring and a 12T rear pinion in 0.8 module to match the stock geometry and allow direct replacement on the listed models.

Manufactured from 20CrMnTi steel and given a hardened black surface treatment, the gears are designed to improve resistance to wear during heavy RC use while maintaining smooth meshing thanks to the spiral-cut design. The set directly replaces factory items ARA-3294+ARA-2672 and is supplied as the ring and pinion pair.

Fitment notes: the gears come pre-assembled in the kit; fit with care and consider a medium-strength screw adhesive on fasteners to avoid loosening. Verify gear mesh and backlash at the stock 0.8 module, and confirm differential function before full-power running.

Opt for this GPM hardened ring and pinion when you require a steel upgrade that preserves original geometry while aiming to lengthen service intervals under hard driving.
