The Rear Axle Shaft is the core component of the transmission system in rear wheel drive or four-wheel drive vehicles, responsible for transmitting the power of the differential to the rear wheels and driving the vehicle.

Power transmission: Transmit the power output from the differential to the rear wheels, pushing the vehicle forward or backward.

Driving stability: Balanced counterweight and rigid design reduce vibration during high-speed driving and improve handling.

Buffer and shock absorption: By designing materials and structures to absorb road impacts, ride comfort is improved.
