This aftermarket rear differential gear set is crafted for ARRMA Mini Kraton 3S 1/16 scale brushless trucks. The kit features a spiral-cut 30T bevel ring and a 12T rear pinion in 0.8 module to maintain stock geometry for direct fitment with the listed models.
Forged from 20CrMnTi steel with a hardened black finish, the gears are intended to offer enhanced wear resistance in high-load RC situations while the spiral-cut form supports smooth meshing. The pair replaces factory parts ARA-3294+ARA-2672 and is supplied as the ring and pinion set.
Fit notes: gears arrive pre-assembled; using a medium-strength screw glue on fasteners is suggested to reduce loosening risk during running. Always confirm backlash and mesh at the stock 0.8 module and verify differential action before high-power testing.
This GPM ring and pinion pair is recommended when a hardened steel upgrade is required to preserve stock fitment and improve longevity under demanding RC driving.
