You may wonder what is a transfer case and why it matters for your car. A transfer case is a part that helps send power from the engine to both the front and rear wheels, making it key for vehicles with all-wheel drive or four-wheel drive. Nearly half of vehicles in the United States, especially trucks and SUVs, use a transfer case for better traction and control. This boost in safety and performance is vital when you drive in rain, snow, or rough terrain. Products like bearing & gear and metal casting parts from JOC Machinery Co., Ltd. support reliable transfer case operation.
