A transfer case is an integral component of the drivetrain in four-wheel drive vehicles, responsible for distributing power from the engine to both axles. This distribution enhances the vehicle's off-road performance, particularly in challenging conditions such as snow and ice. Additionally, the transfer case equips the vehicle with an additional set of gears. These gears shift the transmission into a low-range gear ratio, increasing torque and enabling the vehicle to navigate steep inclines and traverse through snow-laden or muddy terrains effectively.
