YIKONG YK7081 TB8 Rear Hub, 7075 Alloy, Oversized Bearings TB8/022 by GPM  [TB8/022]

Rear hub upgrade for YK7081 TB8

This replacement rear hub fits the YIKONG YK7081 TB8 platform and is catalogued as TB8/022. Made from 7075-T6 aluminium, the hub replaces the OEM 80006 unit and includes oversized inner and outer bearings to address wear points common on 1/8 4WD machines.

Key bearing sizes are an inner 20x30x7mm (original 20x27x4mm) and an outer 15x24x5mm (original 15x21x4mm). These larger bearings increase load area and can reduce lateral play at the wheel hub.

All necessary hardware is supplied pre-assembled. The manufacturer suggests applying a medium-strength screw threadlocker to metal fasteners to prevent loosening in service. Installation is straightforward: remove the stock hub, fit the replacement, confirm bearing seating, and tighten supplied fasteners.

Functioning as an aftermarket upgrade, the hub aims to raise component durability and keep rear-end geometry more repeatable than softer stock parts, helping with consistent traction and suspension setup across different surfaces.

Use this hub to refresh worn rear hubs on YIKONG YK7081 TB8 cars or to fit larger bearings for improved durability; always follow installation checks and use a medium-strength threadlocker on fasteners.
