TRAXXAS TRX-4 HD Brass 12mm Wheel Hex Hubs Adapter, 8mm Thick - JR-TRX417-8MM by Jazrider  [JR-TRX417-8MM]

Durable 12mm brass wheel hex for TRX-4 HD

This is a brass wheel hex hub adapter specifically made to suit the TRAXXAS TRX-4 HD wheel interface and act as a metal replacement hub insert. The adapter employs a 12mm hex engagement and an 8mm body thickness to provide a resilient seating surface between axle hardware and wheel.

It is intended to reduce wear at the wheel mounting point compared with thin plastic hubs; note that adding a metal insert will change offset and may influence how the vehicle tracks. Always trial-fit to confirm clearance around suspension and bodywork.

Fitting requires removing the wheel and existing hub components, pressing the brass adapter into the wheel hex until it seats flush, and refitting the wheel using original hardware. Verify alignment and axial play, then perform a short run to validate installation.

To maintain performance, periodically inspect the brass faces and the hex recess for debris, and ensure the adapter remains firmly seated. Replace when wear produces noticeable play or deformation.
