The JAZRIDER JR-TRX417-8MM HD Brass 12mm Wheel Hex Hubs Adapter is designed for the Traxxas TRX-4 owner who wants a straightforward, durable weight upgrade. At 8mm thick these brass adapters add dependable mass at the wheels to help maintain traction on typical trail and rock lines.
These adapters align with the TRX-4 wheel hex interface and install with standard tools. Brass offers consistent weight and solid wear resistance so the hubs perform reliably under repeated crawling sessions and light maintenance cycles.
Wipe debris away after runs and check fastener torque periodically. The brass surface is robust but benefits from basic cleaning to prevent grime buildup and ensure a snug fit over time.
