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

7075 alloy rear hub for YIKONG TB8

This RC rear hub is built for the YIKONG YK7081 TB8 platform and carries the designation TB8/022. Constructed from 7075-T6 aluminum, it replaces the stock 80006 hub and comes fitted with larger inner and outer bearings to improve longevity in 1/8 4WD applications.

The upgraded bearings are stated as inner 20x30x7mm (original: 20x27x4mm) and outer 15x24x5mm (original: 15x21x4mm). Increasing bearing size raises the contact surface and can reduce wheel-end play under load.

Hardware and bearings are delivered pre-assembled for convenience. The manufacturer recommends medium-strength screw threadlocker on threaded fasteners to preserve tightness during use. Installation involves removing the original hub, fitting the replacement, checking bearing seating, and securing the fasteners.

As an aftermarket hop-up, the hub increases durability and helps maintain consistent rear-end geometry, giving a firmer hub interface than many stock stamped or softer alloy parts and assisting traction and suspension adjustments.

Install this hub when replacing worn rear hubs on YIKONG YK7081 TB8 cars or when upgrading to larger bearings for better durability; follow routine installation checks and apply medium-strength threadlocker to fasteners.
