4 High vs. 4 Low
When it comes to 4-wheel drive (4WD) systems, there are two modes that are commonly used: 4 High and 4 Low. These two modes are intended for different driving scenarios and offer different benefits.
4 High
4 High is the mode that is typically used in everyday driving situations. It provides better traction and stability on slippery surfaces, such as snow, mud, and sand. In 4 High, all four wheels of the vehicle are engaged, and the engine torque is distributed evenly between the front and rear axles.
The gearing in 4 High is designed to provide a balance of power and speed. Most manufacturers recommend driving at speeds of up to 55 mph in 4 High. Driving at higher speeds can cause excessive wear on the drivetrain and center differential, potentially leading to costly repairs.
4 Low
4 Low is intended for more extreme off-road driving scenarios. It provides maximum torque and power, making it easier to climb steep inclines and navigate through deep mud or sand. In 4 Low, the engine torque is multiplied, and the gearing is designed to provide maximum power and traction.
Driving in 4 Low requires a slower speed due to the increased torque. Most manufacturers recommend driving at speeds of 10 mph or less in 4 Low. Driving at higher speeds can cause excessive wear on the drivetrain and center differential, potentially leading to costly repairs.
It is important to note that driving in 4 Low on dry pavement can cause damage to the drivetrain and center differential. It is only intended for use in extreme off-road scenarios.
Gearing and Engine Torque
The gearing and engine torque are the key differences between 4 High and 4 Low.
In 4 High, the gearing is designed to provide a balance of power and speed, while in 4 Low, the gearing is designed to provide maximum power and torque. The engine torque is also multiplied in 4 Low, providing more power to the wheels.
Center Differential
The center differential is responsible for distributing power between the front and rear axles. In 4 High, the center differential allows for some variation in wheel speed, which is necessary for turning on dry pavement.
In 4 Low, the center differential is locked, providing equal power to the front and rear axles.
Drivetrain
The drivetrain is the system that transmits power from the engine to the wheels. In 4 High, the drivetrain is designed to provide a balance of power and speed, while in 4 Low, the drivetrain is designed to provide maximum power and torque.
It is important to note that driving in 4 Low on dry pavement can cause excessive wear on the drivetrain and center differential.
In my personal experience as an automotive enthusiast, I can confidently assert that 4 High and 4 Low are indeed distinct modes with specific purposes tailored for different driving scenarios.
It is absolutely crucial to employ these modes appropriately to safeguard the integrity of the drivetrain and center differential.
Throughout my years of driving and extensive research on various vehicle systems, I have come to appreciate the significance of using the correct mode in the appropriate situation.
