This is an RC-scale rear hub made for the YIKONG YK7081 TB8 platform, produced by GPM 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 points that commonly affect high-use 1/8 4WD setups.
Key mechanical details provided by the manufacturer include an oversized inner bearing sized 20x30x7mm (original: 20x27x4mm) and an oversized outer bearing sized 15x24x5mm (original: 15x21x4mm). These changes increase bearing contact area and can reduce play at the wheel hub under load.
All included hardware and accessories are delivered pre-assembled. The manufacturer recommends using a medium-strength screw threadlocker on fasteners to maintain stability and prevent loosening during running. Installation requires standard RC maintenance practices: remove the stock hub, fit the new hub onto the axle, verify bearing seating, and secure with the provided fasteners.
As an aftermarket hop-up, this hub primarily serves to increase 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 help when tuning traction and suspension response on both track and off-road surfaces.
Use this hub when replacing worn rear hubs on YIKONG YK7081 TB8 cars or when upgrading to larger bearings for improved durability; follow standard installation checks and apply medium-strength threadlocker to fasteners.
