What do h4l and h4f mean?

h4l and h4f refer to High-speed 4WD (4-wheel drive) and Full-time 4WD respectively. In Full-time 4WD mode, all four wheels of the vehicle are powered, and the wheels can have speed differences. In High-speed 4WD mode, all four wheels are also powered, but the front and rear differentials are locked. Many high-performance off-road vehicles offer different 4WD modes. The basic 4WD modes include Full-time 4WD, High-speed 4WD, and Low-speed 4WD. When the vehicle switches to Low-speed 4WD mode, the wheel torque is amplified, which helps the vehicle escape difficult terrain more effectively. All vehicles are equipped with differentials. When turning, the left and right wheels rotate at different speeds. When the differential is engaged, power is evenly distributed to the left and right tires, enabling the vehicle to quickly free itself from challenging situations.
