Precision aluminum wheel hex for Promoto-MX

This aluminum rear wheel hub hex is an RC-scale replacement crafted for the Team Losi Promoto-MX motorcycle platform and sold as the Jazrider JR-LMX03-DB. It replaces the factory plastic hex to deliver a firmer interface between axle and wheel, helping keep wheel positioning more consistent across running sessions.

Use this part when you require a direct aluminum swap for Promoto-MX compatible rear wheels, focusing on fit and long-term repeatability rather than boosting performance numbers. Fitting involves removing the original plastic hex, inserting the aluminum hex into the wheel hub recess, and refitting the standard wheel fasteners. Check bearing surfaces and final wheel runout before full use.

Will the aluminum hex last longer than plastic?

Aluminum typically resists deformation better than stock plastic, so expect improved dimensional stability under repeated assembly and setup changes.

Is JR-LMX03-DB corrosion resistant?

The part material is aluminum; keep fluids and grit away and consider light corrosion-prevention if you run in wet or salty conditions.

Should bearings be replaced when fitting?

Inspect the bearing face and hub recess for wear; replace bearings if there is play or visible damage to ensure proper seating.
