And when one of the wheels rotates forward, the wheels on the other side will not rotate in the opposite direction like the bead differential or tooth differential, because there is no connection effect of the umbrella teeth or steel balls in the middle. Later, when you turn one of the front wheels backwards, you will find that this will push the rear wheels to rotate, but the front wheels on the other side may still not rotate, which is the feature of installing the front one-way. In addition, the front one-way is not like a differential. When one wheel is decelerated, the reverse force is transmitted to the other wheel. The two only move forward independently of each other, like 2WD without wheel axles. This is the one-way differential method. In addition: To everyone, don’t install the differential like the gear. Before installing, check the front wheel and open the throttle. This will immediately damage the front direction or gears. Remember!                 What is the role of the header? Head (front one-way) effect      These characteristics of the front one-way are also due to the characteristics of allowing the front wheels to rotate freely forward, which makes the front wheels decelerating or braking. It can achieve the effect of braking only the rear wheels when braking, which is equivalent to the hand brake.Specifically, the drift performance on the mini q is that the front is more flexible, especially when doing a rollover, and the pendulum drift is very advantageous. When you move forward and brake suddenly, the rear wheels brake, and the front wheels still have a certain inertia to make the front wheels continue to roll, thus improving the flexibility of the front and more accurate drift angle. [Because it is a one-way bearing, the front wheels have no power when retreating, which is normal.]  Installation method: Remove the front wheel differential of the original car, and install the header on the position of the front wheel differential, instead of the position of the differential. (Note: Bearings are not included in the header, please replace the bearings on the original differential with the header.
