As a critical component of a vehicle's drivetrain, a differential kit enables the wheels on both sides to rotate at different speeds. This not only ensures smooth vehicle operation during turns but also intelligently distributes power, thereby enhancing both handling stability and off-road capability.

Characterized by a simple structure, reliable operation, and low cost, this type is well-suited for driving on paved urban roads. However, on slippery surfaces or in off-road conditions, this differential is prone to single-wheel slippage, resulting in significant power loss.

Capable of locking the wheels on both sides to ensure they rotate in unison, this mechanism significantly improves traction on low-grip surfaces. Conversely, when turning on dry paved roads, this device may accelerate tire wear and compromise the smoothness of handling.

Strikes an excellent balance between traction and handling performance. It permits slight rotational speed differences between the wheels while automatically distributing power to the wheel with superior traction, making it suitable for a wide range of driving scenarios; however, this device features a relatively complex structure and comes at a comparatively higher cost.
