Products Description
The AZ9231320261 is also called a through shaft, designed for HOWO's HC16/AC16 rear drive axles. Its role is simple yet critical:
Power Transmission: Transfers rotational torque from the differential side gear to the wheel hub, driving the rear wheels.
Load Bearing: Withstands heavy torque and impact loads during acceleration, climbing, and full-load transport.
Compatibility: Works seamlessly with HOWO's differential assembly, ensuring synchronized rotation and reducing power loss.
