By using our differential, your vehicle can rotate the left and right drive wheels at different speeds when turning, avoiding tire slippage or wear. When driving in a normal straight line, our differential can evenly distribute power to the left and right drive wheels, ensuring that the wheel speeds on both sides are basically the same. All vehicles using two wheel drive or four-wheel drive must be equipped with a differential (except for some special models such as tracked vehicles), which is the core device for power distribution of the driving wheels. High strength alloy steel is used and subjected to carburizing and quenching treatment to ensure wear resistance and impact resistance. High precision gear process design, reducing noise and vibration, and improving transmission efficiency.
