Aluminum rear hub hex suitable for Promoto-MX

This aluminum rear wheel hub hex is an RC-scale replacement designed for the Team Losi Promoto-MX motorcycle chassis and marketed as the Jazrider JR-LMX03-DB. It replaces the stock plastic hex to form a firmer connection between the rear wheel and axle, aiding in consistent wheel placement during setup and use.

Intended for direct swaps on Promoto-MX compatible rear wheels, this hub emphasizes correct fitment and repeatable alignment rather than claiming performance enhancements. Installation requires removing the original hub, seating the aluminum hex in the wheel hub recess, and securing with the existing wheel hardware. Inspect contact surfaces and bearings for correct fit and verify wheel runout after fitting.

Is JR-LMX03-DB a direct swap for the stock part?

Yes, it is designed for direct replacement on compatible Promoto-MX rear wheels, though a physical fit check is recommended before final assembly.

Will this part affect wheel balance?

If installed correctly and seated fully, the aluminum hub should not negatively affect wheel balance; verify wheel spin and runout after installation.

What should I inspect during fitment?

Confirm the hub seats flush in the wheel, bearings are undamaged, and there is no interference with swingarm or brake components before operating the motorcycle.
