This rear axle hex is intended for use with LOSI PROMOTO-MX rear wheels and is identified as MX007. Crafted from 7075-T6 aluminium, the component delivers a stiffer mounting surface compared with stock plastic parts, helping maintain geometry under load.
The hub accepts larger inner bearings and contains a bearing positioning column to support correct seating during assembly. Bearings included match standard RC sizes listed below and allow the hub to be used with the Promoto-MX rear wheel and mainshaft given compatible drivetrain parts.
For tuning and servicing the rigid aluminium hub reduces lateral play at the wheel interface and simplifies bearing swaps or tolerance testing. Always check bearing fit and axle hex dimension and use controlled force when pressing bearings to preserve the hub finish.
