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

Hardened rear diff gear set engineered for Mini Kraton 3S

This aftermarket rear differential gear set fits ARRMA Mini Kraton 3S 1/16 scale brushless trucks. The kit provides a spiral-cut 30T bevel ring and a 12T rear pinion in 0.8 module to match stock geometry for straightforward fitment to the listed models.

Machined from 20CrMnTi steel and finished with a hardened black surface, the gears are intended to increase wear life under high-load RC operation while preserving smooth engagement via the spiral-cut teeth. The set replaces factory parts ARA-3294+ARA-2672 and is supplied as the matched ring and pinion pair.

Installation notes: the gears are supplied pre-assembled in the kit; using a medium-strength screw glue on fasteners is advised to limit loosening during use. Set and check backlash with the stock 0.8 module mesh, and confirm differential action before applying full power.

Choose this GPM replacement ring and pinion when a hardened steel option is needed to retain stock geometry and extend gear life under aggressive RC running.
