It is designed to protect and support the gears while also providing a sealed environment for lubrication. The Gear Housing is typically made from cast iron or aluminum alloy, which provides durability and heat dissipation properties. It is responsible for transmitting power from the engine to the wheels through a series of gears that are engaged by shifting mechanisms. The Part Number 3963834 refers to a specific model or version of Gear Housing that may be used in various types of trucks.
