ARRMA MINI KRATON 3S Aluminum Rear Hub 7075-T6 Upgrade MAKM022 by GPM  [MAKM022]

7075-T6 machined hub for ARRMA MINI KRATON 3S

This aftermarket rear hub is produced from 7075-T6 aluminum and targets 1/16 scale ARRMA MINI KRATON 3S platforms. The component replaces the stock plastic hub to give greater stiffness and improved wear characteristics by using higher-grade alloy and larger rolling elements. It replaces factory item ARA-2677 and includes upgraded inner and outer bearings to suit the revised bore and load profile.

The primary mechanical revision is an inner bearing size of 7x17x5mm and an enlarged outer bearing of 7x14x5mm, compared with the original 7x14x4mm inner and outer bearings. These changes influence fitment at the axle/hub interface and can reduce lateral play while extending service intervals under frequent off-road operation.

Components are delivered pre-assembled for faster installation, and the package contains the parts needed for a direct swap of the rear hub assembly. For reliable fastening we recommend using medium-strength screw glue on bolts where threadlocker would normally be applied to avoid loosening from vibration.

A bolt-on aluminium replacement aimed at MINI KRATON 3S pilots who prioritise durability and upgraded bearing sizing over the original plastic hub.
