YIKONG YK7081 TB8 Rear Hub Upgrade 7075-T6 Alloy, Larger Bearings - TB8/022 by GPM  [TB8/022]

Durable rear hub for YIKONG TB8

This RC-scale rear hub is designed for the YIKONG YK7081 TB8 platform and is listed as TB8/022. Machined from 7075-T6 aluminum, the hub replaces factory part number 80006 and is supplied with larger inner and outer bearings to address wear on heavily used 1/8 4WD setups.

Manufacturer-specified bearing upgrades are an inner 20x30x7mm (original: 20x27x4mm) and an outer 15x24x5mm (original: 15x21x4mm). The increased contact area helps reduce play at the wheel hub under load.

All included hardware and accessories arrive pre-assembled. The manufacturer recommends using a medium-strength screw threadlocker on fasteners to maintain stability and prevent loosening during running. Installation follows standard RC maintenance: remove the stock hub, fit the new hub onto the axle, verify bearing seating, and secure with the supplied fasteners.

As an aftermarket hop-up, this hub is aimed at improving component durability and repeatability of rear-end geometry. Expect a stiffer, more consistent hub interface compared with the original stamped or softer alloy part, which can assist traction and suspension tuning on both track and off-road surfaces.

Use this hub to replace worn rear hubs on YIKONG YK7081 TB8 cars or when upgrading to larger bearings for improved durability; perform the usual installation checks and apply a medium-strength threadlocker to fasteners.
