TRAXXAS TRX-4 HD 12mm Hex Wheel Hub Adapter (8mm thick) - JR-TRX417-8MM by Jazrider  [JR-TRX417-8MM]

Replacement brass hex hub for TRX-4 HD

This RC wheel hex hub adapter is manufactured as a brass replacement insert to suit the TRAXXAS TRX-4 HD wheel interface. It uses a 12mm hex coupling and an 8mm thick body to produce a reliable metal contact area between axle hardware and wheel.

The component is aimed at preventing wear where stock plastic hubs typically degrade; note that adding the brass adapter will change offset and could require clearance checks. Always confirm fit on your chassis and body panels before extended running.

Installation follows standard hub replacement steps: take off the wheel, remove existing hub parts, press the brass adapter into the wheel hex, and secure with the original wheel fasteners. Check for axial play and correct wheel alignment, then test at low speed to ensure no interference with suspension travel or bodywork.

For upkeep, keep the hex recess free of grit, inspect seating surfaces for signs of wear, and confirm the adapter remains firmly seated after each session. Replace the adapter if wear leads to wheel movement or misalignment.
