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

Upgraded rear axle hub — YK7081 TB8

This is an RC rear hub designed specifically for the YIKONG YK7081 TB8 platform, identified as TB8/022. The part is machined from 7075-T6 aluminum and replaces the factory 80006 hub, supplying larger bearings to address common wear areas on 1/8 4WD vehicles.

Specified bearing dimensions are inner 20x30x7mm (stock 20x27x4mm) and outer 15x24x5mm (stock 15x21x4mm). These larger bearings increase contact surface and can reduce lateral play at the wheel hub.

All hardware and bearings are supplied assembled. The manufacturer advises using a medium-strength threadlocker on metal fasteners to avoid loosening during use. Installation requires basic RC service steps: remove old hub, fit new hub, confirm bearings are seated, and tighten fasteners.

As an aftermarket upgrade, the hub focuses on extending part life and providing a more repeatable rear geometry compared with softer stock pieces, which helps when dialing in traction and suspension response.

Choose this hub when renewing rear hubs on YIKONG YK7081 TB8 cars or when you want larger bearings for improved longevity; follow standard installation checks and apply a medium-strength threadlocker to fasteners.
