ARRMA MINI KRATON 3S Front Hub & Steering Blocks 7075-T6 MAKM021 by GPM  [MAKM021]

Aluminum front hub and steering block upgrade

This replacement front hub and steering block set is an RC-scale accessory designed for ARRMA 1/16 MINI KRATON 3S models. Machined from 7075-T6 aluminum, the parts use enlarged inner and outer bearings sized 7x14x5mm compared with the original 7x14x4mm bearings to provide a tighter press fit and reduce play at the wheel interface.

The set is intended to replace the factory item ARA-2676 and installs as a direct swap into stock suspension knuckles on compatible MINI KRATON 3S chassis. Because these components affect front steering geometry and load transfer through the suspension, they are useful when setting up a scale 1/16 off-road truck for more consistent steering feedback or when repairing worn stock hubs.

All included components are pre-assembled in the package, and it is recommended to apply a medium-strength screw glue on fasteners during installation to maintain assembly stability and limit loosening under vibration.

This upgrade supplies a stronger alloy hub and larger bearing seats intended for direct replacement of worn or stock hubs on 1/16 MINI KRATON 3S trucks; follow standard RC maintenance practices and use medium-strength threadlocker where recommended.
