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

12mm brass hex hub insert for TRX-4 HD

This adapter is an RC-scale brass hub insert made to match the TRAXXAS TRX-4 HD wheel interface. It features a 12mm hex coupling and an 8mm thick body to create a firm metal seating surface between the axle hardware and the wheel.

Use it where stock plastic hubs are prone to wear — the brass contact surface increases durability but will alter wheel offset and possibly clearance. Always check chassis and body clearances when fitting aftermarket components.

To fit: remove the wheel and existing hub parts, align and seat the brass adapter into the wheel hex, then secure with your existing wheel hardware. Verify there is no axial movement and confirm wheel alignment before driving the vehicle.

Routine care includes removing grit from the hex recess, checking the brass faces for wear, and ensuring the adapter remains tightly seated after runs. Swap it out if you observe deformation or persistent wheel wobble.
