The JAZRIDER JR-TRX417-5MM brass adapters are a simple upgrade for Traxxas TRX-4 rigs that benefit from extra wheel-end mass. The HD brass construction and 12mm hex sizing help keep tyres planted during low speed manoeuvres.
By increasing unsprung weight, brass hubs reduce sudden lifts and help maintain traction on uneven surfaces. The 5mm thickness provides a sturdy seating area so the hub resists movement under load.
These hex hubs suit serious crawler use as well as scale presentation, combining a functional handling improvement with a metal finish that complements detailed TRX-4 models.
