The JAZRIDER JR-LMX03-PU aluminium rear wheel hub hex is intended as a durable service part for Team Losi Promoto-MX owners. It provides a stronger interface than typical plastic hexes and fits standard wheel assemblies to deliver repeatable wheel positioning under load.
Produced for practical hobby use, the aluminium construction reduces deformation and extends the service interval versus stock plastic components. This makes it a straightforward upgrade for enthusiasts who want parts that require less frequent replacement during regular running.
Designed to match Team Losi Promoto-MX mounting points, the hub hex installs using common hand tools. Inspect contact surfaces and fasteners during routine maintenance and ensure components are clean before assembly to maintain a tight, reliable fit.
