What is the difference between low-range 4WD and high-range 4WD?
1 Answers
4L stands for low-range four-wheel drive. The transfer case has a larger gear ratio, which amplifies torque while reducing speed, thereby increasing power. It is suitable for extremely harsh road conditions. 4H stands for high-range four-wheel drive, where the transfer case has a smaller gear ratio, allowing for relatively higher speeds but with less guaranteed power. It is suitable for general light off-road conditions. Below are relevant details: 1. Part-time four-wheel drive is a system where the driver can manually switch between two-wheel drive and four-wheel drive. By engaging or disengaging the transfer case, the driver can achieve either two-wheel or four-wheel drive based on driving needs. This is the most common four-wheel drive system found in off-road vehicles or SUVs with 4WD capability. 2. Part-time four-wheel drive systems typically have three modes: 2H, 4H, and 4L (switched via the transfer case), commonly referred to as two-wheel drive, high-range four-wheel drive, and low-range four-wheel drive. Two-wheel drive mode is more suitable for city roads or paved surfaces. High-range four-wheel drive is ideal for gravel roads, while low-range four-wheel drive is best used for off-road climbing or recovery situations. Switching can be done via a traditional gear lever, buttons, or a rotary knob.
