ARRMA MINI KRATON 3S Rear Hub Upgrade 7075-T6 (larger bearings) MAKM022 by GPM  [MAKM022]

7075-T6 aluminum rear hub for MINI KRATON 3S

This aftermarket rear hub is machined from 7075-T6 aluminum and is made for 1/16 scale ARRMA MINI KRATON 3S models. The design improves durability compared with the stock plastic hub by using higher grade aluminum and larger rolling elements as specified. It directly replaces the factory item ARA-2677 and is supplied with upgraded inner and outer bearings to match the revised bore and load requirements.

Key mechanical changes carried over from the manufacturer notes are the inner bearing size of 7x17x5mm and an enlarged outer bearing of 7x14x5mm, compared with the original inner and outer sizes of 7x14x4mm. These bearing dimensions affect fitment at the axle and hub interface and can reduce play while improving longevity under frequent off-road use.

All included parts arrive pre-assembled for convenience, and the package contents are supplied to allow a straight swap of the rear hub assembly. For secure installation we recommend using medium-strength screw glue on fasteners where threadlocking is normally applied to prevent loosening during high-vibration running.

This hub is an RC-scale replacement part focused on durability and bearing upgrades for MINI KRATON 3S owners seeking a direct bolt-on aluminum alternative to the stock rear hub.
